Re: Free trial period for apps in Mac App Store (?)

[Dave via Cocoa-dev]

Hi,

The “Light” version doesn’t take much more effort to support since its built 
from the same source code. I actually found this the easiest and most straight 
forward way of doing it.

Cheers
Dave

Re: Free trial period for apps in Mac App Store (?)

[Dave via Cocoa-dev]

Hi,

It depends on how you want to play it. In the past I’ve done the following:

Make a “Lite” version free (Price 0.00) which has either a limited life span or 
limited functionality or both.
Make a “Full” version pad for version (Price X.00) which has either a limited 
life span or limited functionality or both.
When the time expires or the user decides they want more functionality they 
click a link to the App in the AppStore.

The other option is to use “In App Purchases” to upgrade the functionality.

Hope this helps.

Cheers
Dave

Re: NSTimer +timerWithTimeInterval:

[Dave via Cocoa-dev]

Hi,

I’d try this:

Make a method called setupTimer with the code below.

Then in applicationDidFinishLaunching call performSelector: setupTimer with a 
delay of (say 5 seconds).

Just to see if it changes anything….

Re: [OT] NSTimer +timerWithTimeInterval:

[Dave via Cocoa-dev]

Yes, that’s correct, nothing wrong with a method beginning with new as long as 
it follows the rules, I use it all the time.

I’m not sure if it matters at all with ARC, but I stick by the rules anyway.

Re: applicationDidFinishLaunching not being called

[Dave via Cocoa-dev]

Look at the Application Object in the Workspace/NIB file, is the class 
AppDelegate? If not it should be! Do you have an AppDelegate in the 
project/target and is the correct target set for it?

BTW, these questions are better posted to the Xcode list.

Re: Sharing NIB/XIB between different apps?

[Dave via Cocoa-dev]

Hi,

If you decide to use multiple targets then it’s still better to have a folder 
for common files and one for each target, both targets include the Common 
folder but you only include the folders appropriate for each Target. By 
“include” I mean you check/uncheck the targets that the file builds against, so 
Common files are checked for to project and the specific files only for the 
target they belong to.

You can also use a “Workspace”, which is what I tend to do, you then add 
projects to the work-project (which can have sub-projects), it’s all a bit 
complicated to be honest, but the docs are pretty good. The best way to find 
out more, is to find a Sample project that  uses a Workspace and go from there. 

Hope this helps
Dave

Re: Sharing code between screensaver and regular app

[Dave via Cocoa-dev]

Hi,

All I can think of that this behaviour has changed on your version of 
MacOS/XCode.

You can do the same thing as the template by manually adding the files, e.g 
copy your “ViewController” file, rename it and then add it to the new project. 
You will need to make sure that the Storyboard/Nibs are the same too. Ether add 
the elements needed yourself or copy the existing storyboard/nib(s) rename and 
add to the new project. 

All the Best
Dave

Re: Sharing code between screensaver and regular app

[Dave via Cocoa-dev]

Hi,

You need to create a project with the right template to start with. In XCode:

File/New Project - Select MacOS and then “App” (from the New Project Dialog).

On XCode 11.0 and MacOS 10.14.6, this results in a new project Setup with a 
view controller.


There are a number of ways to share code between Apps.

I usually have a folder structure like this:

CommonSource
ScreenSaver
StandaloneApp

Put the code that is common between the two into “CommonSource” and the App 
Specific Stuff into either “ScreenSaver” or “StandaloneApp”. Then add the 
common files to both projects and compile as normal.

All the Best
Dave

Re: NSManagedObject.managedObjectContext is nil???

Just to clarify, the moc exists, but the reference to it is nil? Or has the

Set up an observer for that notification for your MOC and set a breakpoint in

Re: Need a direction. App crash in CoreData while loading a window's nib

[Dave Fernandes]

Does your code modify anything in the persistent store during loading 
(NSManagedObjectContextDidChangeNotification)? Maybe it is rounding some values 
for display? This might cause infinite recursion with bindings.

NSManagedObjectContext's undoManager is nil on macOS

[Dave Fernandes]

The docs say:
"In macOS, a context provides an undo manager by default; on iOS, the undo 
manager is nil by default.”

However, I am finding on macOS 10.13.6, the undoManager is always nil when 
creating a MOC. Is this new behavior expected for High Sierra, or is it a bug?

Well if you consider the use of “gasoline” as an “update” on steam power, I’d 
say the same is true. Gasoline which seemed like “progress” at the time has 
caused more damage to the environment then almost any other man made “device”. 
Which if you turn this back into operating system speak would also be true, I 
mean look how much damage the software version of “gasoline” has caused!

Why not? They used to do a *much* better job when they had much lesser

I agree with Alex, reporting bugs in a total waste of time these days.

How to Correctly Add subviews considering auto layout

[Dave]

iOS - Landscape Only.

Hi,

I have a View Controller in a Storyboard that contains a hierarchy of Stack 
Views, the leafs are a Custom Class that inherits from UIView. The Custom Class 

LTWGameCellView : LTWDrawFrameView

LTWDrawFrameView is Custom Class has methods in it that draw a frame around the 
View - this works fine.

LTWGameCellView inherits from LTWDrawFrameView and add up to 2 UIImageView 
subviews to itself. The Images are resources in the project that are loaded at 
runtime and added to the LTWGameCellView. The idea is to draw a Frame Around 
but the Image, but also to inset the image a small amount.



I’m using auto layout and it works ok, except that I’m not sure I’m what I’m 
doing is correct taking into account auto layout - please see code below. The 
“setCellAsPlayedWithPieceImage:" is called when the a player plays a piece into 
the Cell.

I want the (smaller) image to be centered in the (square) DrawFrame View.

Firstly I’m unsure if self.bounds is the correct starting place for placing the 
image view and if I should be setting the frame anyway? Maybe I should be 
adding a constraint to the Image View before I add it as a subview?

The problem I am seeing is that on the first run, the board is not setup 
correctly in that the frames are different, if I re-restart a new game after 
the first time, all is well. This is *was* being called from the 
“viewWillAppear:" of the owing view controller (see code below), so I changed 
things so that “newGame” is called from “viewDidAppear:”, this works well BUT 
you see an annoying flicker when the View Controller first opens.

Any advice or help on this would be greatly appreciated.

All the Best
Dave

-(void) viewWillAppear:(BOOL) theAnimateFlag
{
[super viewWillAppear:theAnimateFlag];

[self newChaosCellViewDictionary];
//[self newGame];
}


-(void) viewDidAppear:(BOOL) theAnimateFlag
{
[super viewDidAppear:theAnimateFlag];

[self newGame];
}

These are the methods I am using to create the ImageViews and add them as a 
subview.

The "setImageForCellWithImageFilePath:” setup up an Image View and stores it as 
a property. Then, later on  “setCellAsNormal” is called to Add the subview, 
then later still, “setCellAsNormal'





-(void) setImageForCellWithImageFilePath:(NSString*) theImageFilePath
{
UIImage*myImage;
UIImageView*myImageView;

//**
myLineWidth = kLTWChaosCellViewFrameLineSize;

//**
//**Inset the Image Rectangle
//**
myImageFrameRect = self.bounds;
myImageFrameRect = CGRectInset(myImageFrameRect,myLineWidth,myLineWidth);

myImage = [[UIImage alloc] initWithContentsOfFile:theImageFilePath];
if (myImage == nil)
{
LTWAssertAlways(@"Cell Image Could Not be Found");
return;
}

//**
//**Create the Image View
//**
myImageView = [[UIImageView alloc] initWithImage:myImage];

}

self.pCellKind = kLTWChaosBoardCellKindNormal;

[self setBackgroundColor:self.pCellUIColor];
[self removeAllSubviews];
[self addSubview:self.pCellImageView];
}

{
UIImageView*myImageView;
CGRect  myFrameRect;

myFrameRect = self.bounds;
myFrameRect = CGRectInset(myFrameRect,6,6);

[myImageView setFrame:myFrameRect];
[myImageView setBackgroundColor:[UIColor clearColor]];

//**

Re: file encription/decriptoin iOS

[Dave Fernandes]

Ah. Thinking about the new device use case helps. Everything must be accessible 
and decryptable using only the iCloud passphrase. But if the same passphrase is 
used both to authorize access to the data and to decrypt it, then Apple has the 
passphrase to decrypt each time the user logs in, do they not? So encryption 
prevents against third parties seeing the data, but not Apple itself. Or 
perhaps the passphrase is used to generate two independent secrets and the 
passphrase itself is never sent over the wire?

I didn’t realize this, and went to the iOS Security Guide to get more details, 
but I am left more confused than when I started. The Security Guide has this to 
say (CloudKit works the same way):

iCloud Drive

iCloud Drive adds account-based keys to protect documents stored in iCloud. As 
with existing iCloud services, it chunks and encrypts file contents and stores 
the encrypted chunks using third-party services. However, the file content keys 
are wrapped by record keys stored with the iCloud Drive metadata. These record 
keys are in turn protected by the user’s iCloud Drive service key, which is 
then stored with the user’s iCloud account. Users get access to their iCloud 
documents metadata by having authenticated with iCloud, but must also possess 
the iCloud Drive service key to expose protected parts of iCloud Drive storage. 


So everything is protected by the iCloud Drive service key, but what does 
“which is then stored with the user’s iCloud account” mean? Is it stored on the 
device or in iCloud? That makes all the difference.

I posted this a while back as a separate question but got no replies:

I have two iOS projects, in both projects (ProjectA and ProjectB), I have two 
view controllers in both Apps, one is the Initial View Controller and the other 
is presented via Button Click.

In ProjectA this works ok.

In ProjectB it crashes in main.m.

When I look in the Storyboard file in both projects, I see that in ProjectA 
there is a Segue from a Button to the Destination, when I inspect the Segue, to 
shows the Kind as being “Show (e.g. Push)".

However, in ProjectB is says “Push” and I can see no option for “Show” (as far 
as I remember when I created ProjectA, it said Push was deprecated).

I’m not sure if this is causing the crash, but why it is different in the two 
projects?

How can I fix this crash? I can’t see anything in the Storyboard or .m files 
that is different except the Segue “Kind” field.



I think I see what the problem is now and how it came about. I think it depends 
on what template you chose to create the initial project.

I think if I make (or embed?) my Setup (Root) View Controller in a Navigation 
Controller it will solve a lot of the issues I’m having. I’ll look into it 
further,

All the Best
Dave

That’s part of the problem with I’m having with Segue’s. It does not give me 
the option for show anymore, I get Push, Model, Custom but (since I updated 
XCode I think), it no longer gives “Show” as an option. In another iOS project 
I have, if I look at the Storyboard, it shows these Segue’s as “Show 
(Deprecated)” but I can find no more info about it.

Re: Help with Storyboard Problem

[Dave]

A bit more on this:

I tried it with a NIB as so:

-(IBAction) startGameAction:(id) theSender
{
LTWBoardViewController* myGameViewController;
UIView* myView;

myGameViewController = [[LTWBoardViewController alloc] 
initWithNibName:@"LTWBoardViewController" bundle:nil];

myView = myGameViewController.view;
}

And this doesn’t work either….. Even though it says in the docs that it should 

All I want to do is to call one view controller from another, this used to be 
soo simple!

If anyone could tell me how to present the view controller on the screen I’d be 
really grateful. 

All the Best
Dave

Converting a Storyboard into separate NIBs.

[Dave]

Hi All,

I have an iOS project that I have made the mistake of using storyboards on. At 
the moment, I only have one fairly complex view controller and I think it would 
be better to move to NIBs now before wasting anymore time trying to get 
Storyboards to work. 

Can anyone tell me if this is an easy process or not? I mean can I just 
copy+paste from the Storyboard into a NIB file or better still is there a way 
to export to a NIB?

All the Best
Dave

Help with Storyboard Problem

[Dave]

XCode 8.3.3.

Hi All,

I’m using storyboards on an iOS project and can’t seem to get it to work.

I have two view controllers in the “Main.storyboard” file. The fist view 
controller has one button on it, that when clicked, I want it to go to the 
other view controller.

I’ve tried using Segues but can’t get that to work so decided to to it manually.

I have a method in the first view controller that is hooked to the button as so:

-(IBAction) startGameAction:(id) theSender
{
LTWChaosBoardViewController*myGameViewController;
UIView* myView;

myGameViewController = [self.storyboard 
instantiateViewControllerWithIdentifier:@"LTWChaosBoardViewController1”];
myView = myGameViewController.view;
}

This returns the correct View Controller but does not actually present it. How 
do I do this? 

The documentation is sooo poor that I just can’t find anything that is of 
help.

All the Best
Dave

I’m only on XCode 8.3.2 and I can’t update at the moment because I have a VERY

Is there nothing I can just download?  It seems to me there used to be loads of 
documents telling you have to do this, but they all seem to have disappeared?

Re: iOS Drag and Drop

[Dave]

Hi,

I should have said I’m using Objective-C not Swift and I’d much rather have 
some written docs then a video for a number of reasons, the main one being I 
have limited Internet access at the moment and I can’t find a way to download 
the videos anymore…… Also, I find it takes much longer to keep on stopping a 
video and then doing a bit in XCode. I’d much rather a simple Sample App

iOS Drag and Drop

[Dave]

Hi,

Can someone point me to some documentation of Drag and Drop for iOS please?

I done loads of searches but can’t find a brief intro and some Sample Code.

I’ve not been working on iOS for some time and things seem to have changed 
quite a lot. 

Cheers
Dave

Problem with Seque's

[Dave]

Hi All,

I have two iOS projects, in both projects (ProjectA and ProjectB), I have two 
view controllers in both Apps, one is the Initial View Controller and the other 
is presented via Button Click.

In ProjectA this works ok.

In ProjectB it crashes in main.m.

When I look in the Storyboard file in both projects, I see that in ProjectA 
there is a Segue from a Button to the Destination, when I inspect the Segue, to 
shows the Kind as being “Show (e.g. Push)".

However, in ProjectB is says “Push” and I can see no option for “Show” (as far 
as I remember when I created ProjectA, it said Push was deprecated.

I’m not sure if this is causing the crash, but why it is different in the two 
projects?

How can I fix this crash? I can’t see anything in the Storyboard or .m files 
that is different except the Segue “Kind” field.

It seems like everything I try to do something with Storyboards there are 
crashes all over the place and I’m beginning to wish I’d not used them and just 
stuck to NIB files. Is there anyway to export View Controllers from a 
Storyboard file into a NIB file?

Thanks a lot 
All the Best
Dave

Drawing a 5 Sided Star Shape

[Dave]

Hi,

I want to draw a 5 sided Star Shape using UIBezierPath. I’ve search for a 
general purpose algorithm, but I can’t find anything that I can get to work 
with Cocoa/Objective-C. 

This code is to go into a UIView subclass in the drawRect: method. 

If anyone has some code that will draw a decent looking star I’d be really 
grateful.

Thanks a lot 
All the Best
Dave

Auto Layout Question

[Dave]

iOS Project.

Hi,

I’m trying to do something with auto layout and I can’t seem to get it right.

I want to create a View that holds a Text Field and a View. Call these LabelA 
and ViewA. I want the Text to appear above the view and i want the View to have 
the same aspect ratio (which is 1:1). I then want the same again, e.g.another 
Text Field and View, positioned in the same manner.

In XCode/IB 8.3.2, here’s what I do:

I create a Label Field, and Set the Text to “Side A", set a custom font of size 
10, call it SideALabel. I create a UIView (call it SideAView) and set its size 
to 35,35 and set the Background Colour to Red. I add an Aspect Ratio constraint 
of 1:1 to SideAView  I then position and resize SideALabel so it has a height 
of 10 and the width is 35 (same as the UIView). I set then an Alignment 
Constraint Leading and Trailing Edges between SideALabel and SideAView. I now 
embed the SideALabel and SideAView in a StackView, call this SideAStackView. It 
now resizes/repositions the Stack and I move it where I want it. When I switch 
to different iPhone’s in XCode/IB it rescales accordingly. 

I actually want two of these Text/Views Combinations, so I duplicate the Stack 
View (call it SideBStackView) and position it to the right of SideAStackView). 
I change the Text to “Side B” and the background color the View to Blue.

  Side A Side B
+—+  +—+
||   |   |  
|   Red  |   |  Blue  |  
||   |   |  
+—+  +—+

The problem is that the StackViews resize so they are of different sizes.

I then embedded  SideAStackView and SideBStackView in another StackView - call 
it SideSelectionStackView, I then set this new StackView’s distribution to 
“Fill Equally” (I’ve also tried “Fill Proportionally” ) and set the spacing so 
there is a gap between SideAStackView and SidebStackView. This almost works, 
except the height of the Text and View Sizes are slightly different. SideA has 
a higher text box/bigger font and the View is slightly smaller. SideB Text is 

I’ve set the Left, Bottom, Right Constraints, so that basically it grows 
upwards from the bottom of the Screen, but because of the aspect ratio it can’t 
get too big. I have another View situated to the right of this and the stack 
view is set to only extend so far from the left of this view.

I’ve tried everything I can think of to make this work but I’ve now run out of 
ideas.

Am I missing something? Maybe I am going about this in the wrong way? 

Any help and suggestions on the best way of doing this would be greatly 
appreciated.

I’m trying to prepare a demo for tomorrow afternoon and it would be really 
great if I could show this displaying correctly.

All the Best
Dave

Re: Autolayout Problem/Question

[Dave]

Hi,

Thanks a lot - That’s what I was looking for! I added a 1:1 Aspect Ratio 
constraint to the Root StackView and it now works ok.

I have another question regarding Auto Layout and XCode.

In XCode/IB I’ve designed these views in Landscape. I started with the iPhone 
4s which is the Smallest I could find in IB and then moved on to iPhone SE, 
iPhone 7 and 7+. These all seem to work ok in Landscape in XCode, but if I 
switch to portrait it stops working.

I want the Root Stack View to be placed to the left of the Screen in Landscape 
and the Top of the Screen in Portrait. Can I do this with one set of 
constraints or is it better to have two separate View Hierarchies and switch 
between them in code?

All the Best
Dave

View Controllers, Views and Storyboards

[Dave]

Hi All,

I have a question about View Controllers in Storyboard’s. 

In the past I have handled Landscape and Portrait Views as two separate 
Hierarchies in XCode/IB. I defined the roots Views inside the View Controller 
but NOT in the main .view. I then hooked these up to the View Controller Class 
as IBOutlets and then adding one or the to the main view in viewWillAppear. E.g.

In IB:

Main “view” - empty.
LandscapeRootView - Hierarchy of Views.
PortraitRootView - Hierarchy of Views.

In the View Controller Class:

@property (nonnull,strong)  IBOutlet UIStackView*   
pPortraitRootStackView;
@property (nonnull,strong)  IBOutlet UIStackView*   
pLandscapeRootStackView;

Then in viewWillAppear:

[self.view removeAllSubviews];
if (Orientation == Portrait)
[self.view addSubview:self. pPortraitRootStackView];
else
[self.view addSubview:self. pLandscapeRootStackView];

However when I come to do this in a Storyboard, I can create the Views OK, but 
it XCode/IB won’t let me hook it up to the Outlets.

I’m using Auto-layout and can’t find a way to make it work with just one view 
hierarchy as the constraints clash.

Any ideas on how to achieve this would be greatly appreciated.

All the Best
Dave

Re: NSBezierPath on iOS?

[Dave]

Hi,

I changed it to use UIBezierPath but now I get errors on the 3 + methods it 
uses - fillRect, setDefaultLineWidth and strokeRect.

From looking at the documentation, I’m guessing that I need to create a path, 
I’ve added this code:

-(void) drawRect:(CGRect) theRect
{
CGRect  myRect;
UIBezierPath*   myPath;

myRect = 
CGRectInset(self.bounds,self.pFrameInsetSize.width,self.pFrameInsetSize.height);
if (self.pDrawPaneFlag == YES)
{
myPath = [UIBezierPath bezierPathWithRect:myRect];
[self.pPaneColor set];
[myPath fill];
}

if (self.pDrawFrameFlag == YES)
{
myPath = [UIBezierPath bezierPathWithRect:myRect];

[self.pFrameColor set];
[myPath setLineWidth:self.pFrameLineWidth];
[myPath stroke];
}
}

Does this look right?

Also, I’m guessing it should be setNeedsDisplayInRect instead of 
setNeedsDisplay,

I changed this to:

[self setNeedsDisplayInRect:self.frame];

Is this correct or should it be self.bounds?

Thanks again.

All the Best
Dave

Autolayout Problem/Question

[Dave]

iOS 

Hi,

I have the following view layout in a Storyboard:

StackView   Vertical
StackView   Horizontal
SquareColorView1
SquareColorView2
SquareColorView3
SquareColorView4
SquareColorView5
SquareColorView6
SquareColorView7
SquareColorView8
SquareColorView9
StackView   Horizontal
SquareColorView1
SquareColorView2
SquareColorView3
SquareColorView4
SquareColorView5
SquareColorView6
SquareColorView7
SquareColorView8
SquareColorView9
StackView   Horizontal
SquareColorView1
SquareColorView2
SquareColorView3
SquareColorView4
SquareColorView5
SquareColorView6
SquareColorView7
SquareColorView8
SquareColorView9
StackView   Horizontal
SquareColorView1
SquareColorView2
SquareColorView3
SquareColorView4
SquareColorView5
SquareColorView6
SquareColorView7
SquareColorView8
SquareColorView9
StackView   Horizontal
SquareColorView1
SquareColorView2
SquareColorView3
SquareColorView4
SquareColorView5
SquareColorView6
SquareColorView7
SquareColorView8
SquareColorView9
StackView   Horizontal
SquareColorView1
SquareColorView2
SquareColorView3
SquareColorView4
SquareColorView5
SquareColorView6
SquareColorView7
SquareColorView8
SquareColorView9
StackView   Horizontal
SquareColorView1
SquareColorView2
SquareColorView3
SquareColorView4
SquareColorView5
SquareColorView6
SquareColorView7
SquareColorView8
SquareColorView9
StackView   Horizontal
SquareColorView1
SquareColorView2
SquareColorView3
SquareColorView4
SquareColorView5
SquareColorView6
SquareColorView7
SquareColorView8
SquareColorView9
StackView   Horizontal
SquareColorView1
SquareColorView2
SquareColorView3
SquareColorView4
SquareColorView5
SquareColorView6
SquareColorView7
SquareColorView8
SquareColorView9


The SquareColourView is a View that displays a coloured Rectangle with a Frame 
around it.

I have designed this in a Storyboard and started on the lowest resolution 
iPhone (4s). On the  4s each Coloured view in the Stack View is Square.  I then 
switch to a iPhone 7s and because there is now more space available, the inner  
SquareColorView’s are stretched horizontally. I want them to grow in size, but 
maintain there “Square” shape, however I can’t seem to figure out how to do 
this with Auto layout. 

Any help or suggestions greatly appreciated.

All the Best
Dave

Re: NSBezierPath on iOS?

Sorry I should have said, this class is a Subview of UIView.

I’m also getting an error on:

[self setNeedsDisplay:YES];

I’m so rusty on iOS and I’m finding hard to remember the differences.

NSBezierPath on iOS?

[Dave]

Hi,

I’m converting a Class from Mac to iOS and I’ve got errors on the following 
code:

if (self.pDrawPaneFlag == YES)
{
[self.pPaneColor set];
[NSBezierPath fillRect:myRect];
}

if (self.pDrawFrameFlag == YES)
{
[self.pFrameColor set];
[NSBezierPath setDefaultLineWidth:self.pFrameLineWidth];
[NSBezierPath strokeRect:myRect];
}
}

It seems that NSBezierPath is not available on iOS, is there something I can 
use that is equivalent to the above on iOS?

All the Best

Re: Video Player Controls?

Hi,

Should have said - this is an iOS project. It would be great if I could just 
get the same graphics for the controls as the Main Player, I could easily wire

Video Player Controls?

[Dave]

Hi All,

(The content of the original message seems to have disappeared!)

I’m using AVPlayer and AVPlayerLayer to play a movie in a view. However when I 
do this I lose the Video Playback Controls (Play/Pause/Fast Forward etc) I get 
when using AVPlayerViewController. Is there a class to handle displaying and 
responding to these controls or do I have to completely roll my own, with my 
own graphics etc?

Thanks a lot

All the Best
Dave

iOS AVPlayerViewController and AVPlayer Documentation/Help

[Dave]

Hi,

The following code plays a movie file in Full Screen, I’d like to be able to 
play a Video inside an arbitrary View with the option to go into full screen. 
I’ve searched for info on this seemingly simple task but can’t seem to find 
anything useful. I’ve tried setting myPlayerViewController.view.frame but this 
doesn’t seem to work. I found some iOS 6 code that I wrote ages ago which does 
this, but of course this has changed so much since then…..

Any help on this greatly appreciated.

All the Best
Dave

I realised that a few minutes after posting. I moved it into viewWillAppear and 
it sort of works, moved it into viewDidAppear and it works BUT the code should 
be:

-(void) viewDidAppear:(BOOL) theAnimatedFlag
{
NSURL*  myMovieFileURL;
AVPlayer*   myPlayer;
AVPlayerViewController* myPlayerViewController;

myMovieFileURL = [[NSBundle mainBundle] URLForResource:@"OrchidDemo-ENG-EX-001" 
withExtension:@"mp4"];
myPlayer = [[AVPlayer alloc] initWithURL:myMovieFileURL];

myPlayerViewController = [[AVPlayerViewController alloc] init];
[self.pMovieView addSubview:myPlayerViewController.view];   
//***

[self presentViewController:myPlayerViewController animated:YES completion:nil];

myPlayerViewController.player = myPlayer;
[myPlayer play];
}

All the Best

Problem Playing Movie File on iOS

[Dave]

Hi,

I’m tying to get a movie to play in iOS. 

I have this in a View Controller. When I run it, it seems to play the file as I 
hear Audio but I get this message in the log:

Warning: Attempt to present  on 
 whose view is not in the window hierarchy!

I’ve search for help on this but I get hundreds of solutions using all kinds of 
different techniques but none of them work. The Apple Documentation is totally 
useless from what I can see and offers no working solutions to build upon that 
I can find.

Here is the code:

-(void) viewDidLoad
{
AVPlayerViewController* myViewController;
AVPlayer*   myPlayer;
NSURL*  myMovieFileURL;

[super viewDidLoad];

myMovieFileURL = [[NSBundle mainBundle] URLForResource:@"Demo-ENG-EX-001" 
withExtension:@"mp4"];
myPlayer = [[AVPlayer alloc] initWithURL:myMovieFileURL];

myViewController = [[AVPlayerViewController alloc] init];
[self presentViewController:myViewController animated:YES completion:nil];

myViewController.player = myPlayer;
[myPlayer play];
}

I’m guess that I need to add a view to the AVPlayerViewController or vice 
versa? 

Thanks in advance for any help.

All the Best
Dave

Basic Question about iOS View Controllers/Storyboards

[Dave]

HI All,

I’ve been working on a Mac Project for a long time and I now have a demo to do 
for an iOS project. 

The last time I worked on iOS was the iOS 6 era and we didn’t use Storyboards 
for that project.

I’m trying to figure out the best template to base the project on, or if there 
is a Sample App that I can adapt that would t tget me on the right track.

For the Demo, I basically need to have a screen that allows the User to select 
a language (at present only English and Spanish) and then play a set of mp4 
movies corresponding to the language selected. I already have the Movies and 
can add them to an XCode project easily. The file names have a pattern of 
Movie-ENG.mp4 or Movie-ESP.mp4 (where NN is the movie number 01 to 99). 

Does anyone have any idea or suggestions where to get started on this?

I’ll probably be doing the Demo in Objective-C (as my Swift code is still very 
sketchy) and then if I get the main contract I will write the end product in 
Swift unless there is a good reason not to.

All the Best
Dave

Determining if an X,Y position will cause a Move or Resize?

[Dave]

Hi All,

I have an X,Y that is in another Application’s Window, is there a way of 
determining if that the Mouse is Dragged at that position whether the Drag will 
be a Window Move or a Window Resize operation. 

Basically I just want to tell if the Mouse is in the Window Title Bar (move) or 
in the Window Frame (resize).

Thanks a lot

Question about the Main Thread

Mac Project.

Hi All, 

I’m using performSelector: withObject: afterDelay: in order to postpone further 
processing until after the current method/run loop as expired, this puts the 
request at the End of the Queue, my question is, is there anyway of putting it 
at the head of the Queue so it gets processing before other requests?

[OT] Question about writing documentation

[Dave]

Hi,

I’m looking for a decent Application that runs on the Mac that will allow me to 
create detailed diagrams of Objective-C Classes. Basically I have a Network of 
inter-related Objects, the Network is represented by Array’s and Dictionary’s 
and I like to do some diagrams showing how each object in the Network is linked.

I’ve tried a few Apps from the App Store and although they are “OK” they either 
buggy for hard to use and don’t have any in-built objects that are suitable for 
representing Classes/Objecrs. The type of diagrams I’d like are similar to the 
ones in the Apple Documentation. 

Thanks in Advance for any suggestions…..

All the Best

iOS Same project question

[Dave]

Hi,

I’ve been working on a Mac project for 2+ years and now I’m trying to refresh 
my iOS knowledge.

I created a New iOS Application in XCode and selected the Page View Template. 
Looking through the code I understand most of it but one thing puzzles me. When 
you move pages the Label at the Top of the Screen changes January, February, 
March, etc. but I can see nothing that actually sets these values? Its 
obviously something that is hidden somewhere, but I’m at a lost to find it in 
the code or the storyboard….

Any help greatly appreciated.

All the Best
Dave

Mobile Cross Platform Solutions

Hi,

I’ve been asked to look at doing a Mobile App for a museum, basically the App 
needs to show info (text, pictures and movies) for each exhibit. I’m wondering 
the best way to make it work for iOS, Android and Windows Phone (maybe). The 
content can be formatted as HTML and I’m wondering if it would be better to 
develop 3 separate “shell” apps, one for each platform or or try to use a 
“Cross Platform” solution. The shell would just display HTML pages, e.g. a 
WebView on iOS but I’m not sure how the other platforms would handle it,

Any ideas/suggestions greatly appreciated.

it used to work much better, then Apple “improved it” and now it is as it is. 
One can only assume they changed it for good reason so why moan about it to 
them. I’ve largely found it a complete waste of time, once Apple decide to 
“improve” something then it is automatically better in their eyes and no amount 
of logic or use (or lack of use) cases can change their minds. Just look at 
XCode code in general…… They probably don’t have the resources to do it 
properly any more as they are spending their money on teams of accountants to 
research tax dodging…..

Dave

Re: Overriding the release mehod

[Dave]

Hi,

Yes, I understand that, but really, I just wanted to know where it was written 
in black and white and I couldn’t find it by searching. I could have worked out 
where it was necessary to override release myself, I just wanted to know the 
effect of calling it and not calling it. Asking why I am doing it assumes that 
is it a) my code I am talking about, b) that I am intending to add it as new 
code, c) that I don’t know what I’m doing as I said I was 99.999% sure that 
it needed to be called in this case but wanted to see it in black and while.

Ok, I was looking in NSObject! 

Yes, I thought so, it occurred to me that I’ve seen instances where singletons 
override release so the (one) version of the object never gets release which is 
what I assume that document means by "your own reference-counting scheme”. I 
never implement singletons that way, preferring to use a factory class that 
allows N of each object to be created and just set N to 1.

Dave

I hate it when people as that question! There are some memory leaks in a 3rd

super. If I call super the leaks go away and all is well. I just want to know 
where is it documented really, I can’t find it searching the docs.

Clarification on MMM rules for init?

[Dave]

HI,


This is for a Mac based App.

I’m looking at some old code and have found what I think is a long standing 
bug. This is a class that has an initWithXXX method which may fail, in this 
case it calls [self autorelease] and returns nil. However, I have found a case 
whereby does a [self autorelease], but instead of retuning nil, it returns 
self. Is this an error?

If so, this framework is being called from an ARC based App, what would be the 
effect of this error on the App?

Re: CoreData headaches

[Dave Fernandes]

The managed objects exist in a MOC whether you have a reference to that MOC or 
not. You can get a reference to the MOC that an MO “belongs to" from the 
-[NSManagedObject managedObjectContext] instance method. Since the properties 
you need are so few and simple, why don’t you just pass these in to the 
NSOperation when you create it on the main thread instead of giving it the 
managed object? Then the MO will never be accessed off the main queue.

Re: CoreData headaches

[Dave Fernandes]

But what managed object are you dealing with? Is the Asset a managed object? If 
so, you can only access its properties from the queue of its managed object 
context. So if it is a main queue context, you can only access the MO’s 
properties from the main queue. If it is a private queue context, you use 
performBlock on the MO’s context to execute a block of code in the context’s 
queue and you must access the MO’s properties from inside that block. If I’m 
stating something you already know, forgive me. It is not clear from your post. 
Example code would help.

Are you accessing the properties from within a 
NSManagedObjectContext.performBlock block? Sounds like you may be accessing the 
managed objects from the wrong queue.

I think you just answered your own question. The relationship management and

If you aren’t dealing with large numbers of objects, then all the optimizations 
in Core Data may not be important to you.

Wow, I’ve never come across that issue. But I don’t see how incrementing it 
after creating it is any different from creating it with a non-zero count. 
Either way, if you have resources available, the count will be non-zero, and 
you will crash if you try to deallocate. But I’m somewhat sure I’ve never seen 
a crash like that. Maybe I was just lucky?

Subclassing and Archiving/Unarchiving

[Dave]

Hi All,

I have an App that produces Archives files that are loaded by another App. The 
Classes that get archived are in a set of common files that both Apps share. 

During the build process I need to carry extra information that only the writer 
app knows about. My first instinct was to create a subclasses in the writer App 
for each Class I need the “extra” information, but of course this won’t work 
because the App that loads the files won’t know about the subclasses.

I was thinking of putting a wrapper around these classes but it is quite ugly 
compared to subclassing. The other thing I could do is to builder a new base 
class from the subclass that mean a lot of  deep copying.

Is there any way that I can get the archiver to just select the Base Class and 
ignore the extra properties in the Subclass? Or is there a better way of doing 
this?

All the Best
Dave

Re: How to update UI from a background thread

Ok, will do thanks a lot. The AppleScript is/should be on the Main Thread. I am 
assuming that the App the Script has finished when it returns but maybe that is 
not the case. I will look into that too.

Thanks a lot for your help.

Re: How to update UI from a background thread

[Dave]

Hi Jens,

There is definitely something fishy going on, I’ll explain the process and how 
I am handling it. There is probably a much better way of doing it and if so I’m 
happy to redesign it.

In order to kick off a Network an third part App needs to be run which starts 
up a process that “looks” for available networks. When it finds one it makes it 
available for my App.

My App needs to grab the state of a Network which is handling by a third party 
package. The only way in which to check if a network is available is to attempt 
to create a Network Object (e.g. myNetwork [[Network alloc] initWithX];). 
If it returns nil, then the Network was not available. So the only way to 
ensure a Network is available is to Poll it. 

My App does this:

User Clicks the  “Connect” button, this launches the Third Party App and then 
runs an AppleScript to tell it to start looking for Network.

The Button handler in my App then starts a timer that Polls the Network every 
0.10 seconds. The Timer handler basically does a Alloc/Init and if it gets nil 
restarts the timer to try again a bit later on. If it gets non nil, then it 
sends a “NetworkConnected” notification. 

The Button Handler then calls “waitForNetworkConnection” which checks if there 
is a valid Network stored in a “connectedNetworksDictionary which is a property 
of the WindowController.
If it is not in the dictionary it calls itself back after a delay. So the 
button handler will return, but the “waitForNetworkConnection” will be called 

The  “NetworkConnected” notification handler then the stores the Network in the 
“connectedNetworksDictionary” property.

Accesses to the “connectedNetworksDictionary” are protected in an @synchronised 
block.

I noticed that the UI stops responding while stepping through the following 
code.

//** THIS STATUS MESSAGE IS SEEN

myNetworkStatusString = [[NSString alloc] initWithFormat:@"Executing Script %@ 
for Target Network: 
%@",myNetworkleScriptFilePath,theNetworkConfigInfo.pNetworkConfigInternalID];
[self updateUIStatusWithInfoMessage:myNetworkStatusString];

myNetworkleScriptSourceString = [[NSString alloc] 
initWithContentsOfFile:myNetworkleScriptFilePath encoding:NSUTF8StringEncoding 
error:&myErrorInfo];
if (myErrorInfo != nil)
{
myNetworkStatusString = [[NSString alloc] initWithFormat:@"Script 
Compile Error %@ for Target Network: 
%@",myNetworkleScriptFilePath,theNetworkConfigInfo.pNetworkConfigInternalID];
[self updateUIStatusWithErrorMessage:myNetworkStatusString];
return NO;
}

myNetworkleScript = [[NSNetworkleScript alloc] 
initWithSource:myNetworkleScriptSourceString];
[myNetworkleScript executeAndReturnError:&myErrorDictionary];
if (myErrorDictionary != nil)
{
myNetworkStatusString = [[NSString alloc] initWithFormat:@"Script 
Execution Error %@ for Target Network: 
%@",myNetworkleScriptFilePath,theNetworkConfigInfo.pNetworkConfigInternalID];
[self updateUIStatusWithErrorMessage:myNetworkStatusString];
return NO;
}

//** UI STOPS UPDATING HERE

myNetworkStatusString = [[NSString alloc] initWithFormat:@"Script Complete %@ 
for Target Network: 
%@",myNetworkleScriptFilePath,theNetworkConfigInfo.pNetworkConfigInternalID];
[self updateUIStatusWithInfoMessage:myNetworkStatusString];

So I’m wondering if it is something to do with the AppleScript handling? The 
Script works ok if I run it from the Script Editor and it compiles and runs ok.

Any help on this would be greatly appreciated.

All the Best
Dave

Re: How to update UI from a background thread

[Dave]

Hi,

This doesn’t work probably because the Class is that is calling back the 
delegate method that updates the Scroll View is also being run on the main 
thread. Sorry I should have said this earlier. I tried updating the UI on a 
background thread and it seemed to work BUT I got warning message from CALayer 
or maybe CATransaction and I think it caused the App to hang.

The time consuming method I am calling is in a third party library and it must 
be called in the main thread. 

All the Best
Dave

How to update UI from a background thread

[Dave]

Hi All,

How can I update my UI from a background thread?

I have a method that does a LOT of intense processing, it calls a delegate 
method in my Window Controller which appends it to a Logging Scroll View, 
however nothing shows up in the Scroll View although it NSLog’s the string ok.

Firstly is it ok to do this? When I tried it I got a CALayer error reported in 
the NSLog output.

All the Best
Dave

Re: NSMenuItem’s userKeyEquivalent lost if changing title

[Dave Lyons]

(Ooh! I know that one!)

The custom shortcut for Finder's File > Compress menu item continues to work, 
because Finder goes slightly out if its way to achieve it.  The item's -title 
remains unchanged as ”Compress”, even when you see "Compress “foo”" or 
"Compress 42 Items” -- in that case, you're seeing the -attributedTitle.  
(Ditto for "Burn to Disc…” item.)

Small downside: If you look carefully while the menu item is disabled, it looks 
a bit different from other disabled menu items.

Yeah, you need to either assign the Array to a strong property OR you need to

Re: Window Opened Notification?

[Dave]

Hi,

I’m already using Accessibility but the notification I get when a window is 
created is posted to too late for it to help in this case.

I’m also using Event Taps, I want to be able to stop events being fired to the 
window until I have received and procesed the Window Created Accessibility 
Notification.

Cheers
Dave

Hi,

>> The two key properties in NSWorkspace

I saw these properties but I don’t think they will do what I want since 
frontmostApplication and menuBarOwningApplication refer to an Application not a 
Window within an Application.

For instance:

Launch Text Edit
Empty Window Opens  - I want to catch this window 
open/create
User creates a New Window   -I want to catch this window open/create

I was wondering if it would be possible to make the Window list Key-Value 
observable? 

I’m Trying to avoid running a timer and polling the Window list.

Window Opened Notification?

[Dave]

Hi All,

Is there any way other that using Accessibility that you can tell when a window 
is opened is any application? Something like a running app notification?

If it is not possible using Cocoa? Is there any way of doing this via the 
Window Server? 

All the Best

On MMM Apps I look at retainCount all the time for debugging, it’s not that you 
shouldn't use it, its more you shouldn’t *rely* on it in active code. The value 
may not be what you expect in that it *might* greater, however if you know what 
your code is doing and you realise that the OS may change, or know that the 
object in question has no possibility of being referred to by the OS, it can be 
useful for debugging purposes.

 For instance on thing I’ve done in the past is to override the “retain” and 
“release”, etc. methods on certain objects and hold my own retain count as a 
separate property of the object, then if “retainCount” is not equal to the 
private retain count, you know the OS has retained it.

Cheers
Dave

Re: Objective-C basics - (Why NSNumber conforms to NSCopying protocol)

[Dave]

Also, beware the “copy” attribute on properties, this *always* creates an 
immutable copy. If you want to copy a Mutable Object you need to explicitly 
call mutableCopy, e.g.

newObject.prop = [self.prop mutableCopy];

I mention this, because if you are writing copyWithZone methods then this will 
bite you!

You should also look at NSCoding, this is the mechanism used to archive and 
unarchive objects (e.g. create (functionally) Identical Copies), once you 
understand how this works, it should be obvious why copy and isEqual work the 
way they do.

All the Best
Dave

Well you have to write a copy method so you can do whatever you want either 
keep the same creation date or change it.

it’s up to you (or the class) to decide what a “copy” means, but the Cocoa 
classes that support copying define their own version of what a copy is.

Don’t forget there are two ways to test that two objects are “Equal”, 

object1 == object2  //Exactly the same object as so by 
definition Equal

[object1 isEqual:object2]   //Functionally Equal

So in the case of the creation date, isEqual would not check the date property 
in the comparison if it didn’t matter…..

> Which, IMHO, means that *all* the values stored in the object must be the 
> same.

All non-object values should be identical, objects should be *functionally* 
identical (and *you* define what functional means, if you need the same 
creation date in one class and a new one in another that’s ok, they function 
differently).

All the Best
Dave

Yes, I guess because in this case then is the possibility of the Mouse/Finger

Re: Keyboard/Mouse Event Interaction

[Dave]

Hi,

Thanks, I’m looking at it now.

I’m a bit confused over the keyboard handling. I would have thought that the 
processing would take place on the KeyUp event, but it seems like its occurring 
on the KeyDown event which is where I am going wrong. 

I’m not sure what use NSKeyUp is in this case? The other thing is that a 
KeyDown with the AutoRepeat flag == YES seems to imply a an NSKeyUp? IOW, the 
events I see are:

NSKeyDown   Repeat == NO
NSKeyDown   Repeat == YES   ) If the Key is held down…..
NSKeyDown   Repeat == YES   )
NSKeyDown   Repeat == YES   )
NSKeyDown   Repeat == YES   )
NSKeyUp Repeat == NO

All the Best
Dave

Keyboard/Mouse Event Interaction

Hi Dave,

I’ve noticed the following behaviour:

In  an XCode Text Window (or any text editor type App), do this:

Click and Hold the Left Mouse Button
Type a character on the keyboard(Nothing happens)
Release the Mouse   (The Character 
appears)

or

Hold down a key on the keyboard so the character is repeating in the text 
window.
Click and Hold the Left Mouse Button(The Characters stops repeating 
in the window)
Release the Mouse   (Many 
Characters appear in the window)

My question is, do the keyboard and Mouse Down Events come in pairs, so that 
the following would/should not occur:

KeyDown Event
MouseDown Event 
KeyUp Event
MouseUp Event

MouseDown
KeyDown
KeyUp
MouseUp

Thanks a lot for any info on this. From looking at it, I think that the 
MouseDown/Up and KeyboardDown/Up must come if pairs with no events to the other 
device(s) in between, but it would be nice to know for sure!

All the Best
Dave

Apple Developer Reference Library Safari Plugin

[Dave]

I posed this a while back and got no response, does anyone know where I can get 
this Safari Plug In from? 

I know its been on this list before but I can’t seem to find the right search 
term for it?

Thanks a lor
Dave

Hi All,

I know this has come up before but after 20 mins of searching I’ve not managed 
to find it.

There is a Safari Plugin that add Apple Developer Reference Library support. I 
used to have this installed but I had to reinstall and I must have forgotten to 
copy it. If anyone could point me to the URL for this I’d be really grateful.

All the Best
Dave

How to Handle Array of Dictionaries when Archiving/Unarchiving?

[Dave]

Hi,

I have an Object that I Archive and Unarchive, e.g it conforms to the NSCopying 
and NSCoding Protocols. The Object in question contains NSArray and 
NSDictionary Object and I handle them like this:

initWithCoder:

myDictionary = [theCoder decodeObjectForKey:@"pLookUpDictionary "];
self.pLookUpDictionary = [[NSMutableDictionary alloc] 
initWithDictionary:myDictionary copyItems:NO];


encodeWithCoder:

[theCoder encodeBool: self.pLookUpDictionary forKey:@"pLookUpDictionary”];


copyWithZone:

myDictionaryCopy = [self.pLookUpDictionary mutableCopy];
myObjectCopy.pLookUpDictionary = myDictionaryCopy;


I now need to add another archivable property as so:

@property (nonatomic,strong)
NSMutableDictionary*>*
pLookUpDictionaryArray;

How do I handle this in the above three methods? Specially do I need to walk 
the Array and do a mutableCopy on each of the Dictionaries in the Array?

All the Best
Dave

CGWindowList Documentation bug?

[Dave]

Hi All,

I got this from CGWindow Reference manual:

Window List Option Constants
Specifies which windows in the current user session to include in a generated 
list.

enum
{
   
kCGWindowListOptionAll
 = 0,
   
kCGWindowListOptionOnScreenOnly
= (1 << 0),
   
kCGWindowListOptionOnScreenAboveWindow
 = (1 << 1),
   
kCGWindowListOptionOnScreenBelowWindow
 = (1 << 2),
   
kCGWindowListOptionIncludingWindow
 = (1 << 3),
   
kCGWindowListExcludeDesktopElements
= (1 << 4)
}

Constants
kCGWindowListOptionAll
List all windows, including both onscreen and offscreen windows. When 
retrieving a list with this option, the relativeToWindow parameter should be 
set to kCGNullWindowID.
kCGWindowListOptionOnScreenOnly
List all windows that are currently onscreen. Windows are returned in order 
from front to back. When retrieving a list with this option, the 
relativeToWindow parameter should be set to kCGNullWindowID.
kCGWindowListOptionOnScreenAboveWindow
List all windows that are currently onscreen and in front of the window 
specified in the relativeToWindow parameter. Windows are returned in order from 
front to back. 
kCGWindowListOptionOnScreenBelowWindow
List all windows that are currently onscreen and in behind the window specified 
in the relativeToWindow parameter. Windows are returned in order from front to 
back. 
kCGWindowListOptionIncludingWindow
Include the specified window (from the relativeToWindow parameter) in the 
returned list. You must combine this option with the 
kCGWindowListOptionOnScreenAboveWindow or 
kCGWindowListOptionOnScreenBelowWindow option to retrieve meaningful results. 
kCGWindowListExcludeDesktopElements
Exclude any windows from the list that are elements of the desktop, including 
the background picture and desktop icons. You may combine this option with the 
other options. 
Discussion
The kCGWindowListOptionIncludingWindow and kCGWindowListExcludeDesktopElements 
constants may be combined with the other constants by adding (or ORing) them 
together and passing the resulting value to the appropriate function.
These constants let you retrieve windows in the current user session only. You 
cannot use them to retrieve windows from other active user sessions running on 
the system. 

Note this:

kCGWindowListOptionIncludingWindow
Include the specified window (from the relativeToWindow parameter) in the 
returned list. You must combine this option with the 
kCGWindowListOptionOnScreenAboveWindow or 
kCGWindowListOptionOnScreenBelowWindow option to retrieve meaningful results. 

Reading the above led me to believe that I had to specify 
kCGWindowListOptionOnScreenAboveWindow or 
kCGWindowListOptionOnScreenBelowWindow in order to retrieve the *one* window I 
was interested in. From experimenting it seems that THIS IS NOT THE CASE, as:

myWindowListOptions = kCGWindowListExcludeDesktopElements | 
kCGWindowListOptionIncludingWindow;
myWindowArray = (NSArray*) 
CFBridgingRelease(CGWindowListCopyWindowInfo(myWindowListOptions,theWindowID));
myWindowInfoDictionary = [myWindowArray lastObject];

Returns the *ONE* info dictionary for the *ONE* window specified by 
“theWindowID”. 

I’ve tested this and it works on 10.10.5 and 10.11 and it works ok. Is this a 
Bug in the documentation? I’m wondering if I should rely on this, if not I’m at 
a loss how to retrieve the Info for the one window I want? When I include the 
Above or Below option, it returns a while load of window info dictionaries I 
don’t care about and this is enough to slow it down so as to cause a 
“juddering” effect.

Any suggestions or help on the would be greatly appreciated.

All the Best
Dave

Re: How to get Window Info Dict for just one Window?

[Dave]

More experimenting:

if I use

myWindowListOptions = kCGWindowListExcludeDesktopElements | 
kCGWindowListOptionIncludingWindow;
myWindowArray = (NSArray*) 
CFBridgingRelease(CGWindowListCopyWindowInfo(myWindowListOptions,theWindowID));

it seems a bit better, but I’m not sure if it is valid or not?

Cheers
Dave

Re: How to get Window Info Dict for just one Window?

[Dave]

Hi,

If I do this:

myWindowListOptions = kCGWindowListExcludeDesktopElements | 
kCGWindowListOptionOnScreenAboveWindow | kCGWindowListOptionIncludingWindow | 
kCGWindowListOptionIncludingWindow;
myWindowArray = (NSArray*) 
CFBridgingRelease(CGWindowListCopyWindowInfo(myWindowListOptions,theWindowID));

Then this works ok, but slows down a LOT when the Window is over a “Crowed” 
area of the Screen(s). Is there no way to get JUST the Window I am interested 
in, e.g. the one Specified by theWindowID (which is obtained from the Info 
Dictionary ONCE via the kCGWindowNumber key).

I cannot believe that there isn’t a function to do this simple thing?

Cheers
Dave

How to get Window Info Dict for just one Window?

[Dave]

Hi All,

I’m using:

myWindowArray = (NSArray*) 
CFBridgingRelease(CGWindowListCopyWindowInfo(kCGWindowListOptionOnScreenOnly,kCGNullWindowID));

To get an Array Containing the Info Dictionaries for all Visible Window, this 
works great, however I think find the Window I am interested in I save it, and 
sometime later I want to retrieve the Info Dictionary for just this one window 
rather than looping through the Array each time.

Is there a function I can use that will just return the Info Dictionary of the 
Window referenced by kCGWindowNumber or some other data in the Info dictionary?

All the Best
Dave
