Re: Localization based on location

It is possible that he or she don't want to learn German and therefore keep using the apps in English. Our apps are localized for 16 languages and always switch to the user’s preference - just using .lproj and NSLocalizedString.

Re: Why is a button in a window not redrawn when I change its state?
Your Button has to draw itself after it called its action.
You try to change state while you are still in the action.
Did you try to performSelector after 0.0?
Am 04.07.2011 um 17:07 schrieb Ulf Dunkel:
In my app's main window, I have a button which should kill a process from the
running system processes. (Guess what - it is helpd.)
In -awakeFromNib:, a private app delegate method -checkHelpd: checks if some
other app has already launched helpd. If so, the button will be drawn as
enabled, else disabled.
When I press the button, another private method -killHelpd: definitely kills
the process, then -checkHelpd: is used again to check whether the button's
state should be disabled or enabled. This triggers a redraw of the window -
or at least should do. But the button is not redrawn (with its new state)
until I toggle the active app from my app to say Xcode and back to my app.
This is the method in my AppDelegate.m which should update the button:
- (void)updateKillHelpdButton
{
[killHelpdButton setEnabled:[self checkHelpd]];
[killHelpdButton setNeedsDisplay:YES];
}
Can someone please tell me what else I should do to force the redraw?
Thank you in advance,

Re: iOS nib weirdness...

I created a new nib to set up a view+controller and added a new tab item to the main nib that references the controller and the controller's nib, plus I filled in some basic functionality in the view controller. Since it's relevant, the controller's IBOutlets are IBOutlet MyTableView* _resultsTable; IBOutlet UIActivityIndicatorView* _searchActivityIndicator; IBOutlet UISearchBar* _searchBar; When I ran the app and used the new view's UI, I got an unexpected unrecognized selector exception when trying to access a custom method in _resultsTable. When I looked at their values in the debugger, I found that _resultsTable was an instance of UITableView, not MyTableView; and _searchActivityIndicator and _searchBar were both nil. I thought that there could be a missing class issue, but the MyTableView class is implemented since creating a test MyTableView instance in code works just fine. That still doesn't explain the other nil values since all three views were wired up in IB: the view controller shows the views connected to the outlets and the views show themselves as connected. Grasping at straws, I trashed the build results and did a clean build, and even re-launched Xcode, with no difference in behavior. I could very well be doing something dumb but I'm not exactly sure where to look since I've (correctly) set up this same sort of thing before and it worked fine.

Re: Accessing NSWIndowController attribute from a subview in IB
Am 28.04.2011 um 13:28 schrieb Ben Golding:
I have a document-based app which loads a couple of NSWindowController
subclasses. That's fine. In one of the subclasses, I load a nib with a
NSView subclass. It wants to access one of the instance vars in the window
controller subclass. I thought no worries, I should be able to hook up a
connection in IB and it will be right.
You can not connect to an ivar/attribute of an object. You can just connect to
an object.
In my NSWindowController subclass (called Face), I have a method:
- (id)initWithSundial:(Sundial *)sundial
{
if ((self = [super initWithWindowNibName:@Face]) == nil)
return nil;
[self setSundial:sundial];
return self;
}
In the window that's loaded from Face.xib, there's a custom view
(SundialView) which needs to access the sundial instance variable in File's
Owner. I just don't seem to be able to control-drag in some order to hook
them up and I think I should be able to.
Am I doing this the wrong way or do I have some sort of misunderstanding
about how this works?
Either or both.
The view itself should not know anything about its controller or the
controllers ivars. Wrong direction.
You should make your WindowController set SundialView's sundial when it has
been loaded. Problem solved.

Will not work in production b) because GKSession does use WLAN, the docs are just wrong c) it is a new iOS 4 feature, the docs just need an update If GKSession is always capable of connecting either using bluetooth or WLAN that would be very nice, as I would be able to dump my WLAN-code.

Then you have the nib inside English.lproj and in the apps directory you still have the nib as a global resource because Xcode does not delete the now localized resources. You said you deleted the build-directory - obviously you did not ;) Delete your build-directory after you localized. Then build again. Will work. atze Am 29.06.2010 um 09:25 schrieb Laurent Daudelin: On Jun 29, 2010, at 02:32, Alexander Spohr wrote: - Change the layout. Does it reflect in the simulator?

Try that and report if it is at the new position in the simulator. If not, you still have some old nib or even an old app around somewhere. OK, it seems to be related with the localization. If I remove the localization for my nib, then I see my changes. If I make the file localized again, then all the future changes I do in Interface Builder don't appear in the build. Of course, I close the document in IB each time I remove the localization or add one. This is really strange as I can't find any other copy of that xib file anywhere in my project. I just reproduced it. I did quit IB, made the files localizable again, then opened one in IB, made a visual change, saved, came back in Xcode, did a clean, build and run in the simulator in debug mode and my change is not visible.

Re: Tracking multiple NSURLConnections
Not sure if I understood the problem. But why not just use the NSURLConnection
objects themselves?
The delegate methods give you the corresponding NSURLConnection.

subclassing or following what I've found in the archives, does this make
sense? Am I missing any details that might cause this to fail?

Re: NSLog and va_list
What exactly so you want?
Either you have an va_list and want to give it to NSLog? Then use
void NSLogv(NSString *format, va_list args);
But I think you want to know what the va_list contains.
Then you just loop over it.
man stdarg will help.
Example:
void foo(char *fmt, ...)
{
va_list ap;
int d;
char c, *p, *s;
va_start(ap, fmt);
while (*fmt)
switch(*fmt++) {
case 's': /* string */
s = va_arg(ap, char *);
printf(string %s\n, s);
break;
case 'd': /* int */
d = va_arg(ap, int);
printf(int %d\n, d);
break;
case 'c': /* char */
c = va_arg(ap, char);
printf(char %c\n, c);
break;
}
va_end(ap);
}

Re: [iPhone] NSManagedObjectContext save doesn't crash but breaks on objc_exception_throw
Is there anything in the log? What does save's error parameter return? atze Am 08.06.2010 um 17:53 schrieb Hank Heijink (Mailinglists): Dear all, I've run into the following problem, and I'm a bit stuck - I wonder if you can shed some light on this. I have an iPhone app that uses Core Data, and the problem occurs when the app terminates. I have an NSOperationQueue with potentially several NSOperations that are cancelled in the applicationWillTerminate: UIApplication delegate method. These NSOperations all have their own copy of an NSManagedObjectContext and an NSManagedObject subclass (I pass them the persistent store coordinator and an NSManagedObjectID that is permanent at that point). Canceling the NSOperation changes an attribute of the NSManagedObject subclass and I save the NSManagedObjectContext on the background thread after this change is made. This means that the NSManagedObjectContext on the main thread is now in conflict, and since all this happens in applicationWillTerminate:, it won't receive the NSManagedObjectContextDidSaveNotification so it can deal with it. My solution to this is to set the merge policy to NSMergeByPropertyStoreTrumpMergePolicy right before saving the main NSManagedObjectContext to give precedence to the already-saved context(s). I haven't been able to find any information about this scenario - the Core Data Programming Guide (in Communicating Changes Between Contexts) seems to suggest my approach (case 3b), although there in-memory changes are preferred over store changes. I always have a break point set on objc_exception_throw, and it hits this breakpoint in the call to save. This is the stack backtrace: #0 0x986d94e6 in objc_exception_throw () #1 0x01dee37c in -[NSPersistentStoreCoordinator(_NSInternalMethods) executeRequest:withContext:] () #2 0x01e22afe in -[NSManagedObjectContext save:] () #3 0x36b6 in -[MyAppDelegate applicationWillTerminate:] ...snip... However, if I remove the break point or hit continue, the application quits with an exit code of 0. If I wrap my [NSManagedObjectContext save] call in a @try @catch block, the @catch statements are never executed. So, is there an exception or isn't there? Should I rethink my approach? I'm just not sure what the issue is here. Any information is greatly appreciated!

Re: Cross XIB references?
Am 05.06.2010 um 23:14 schrieb Jean-François Brouillet: Consider the situation where I have a root ImageView in IB. I specify the actual image I want it to hold by just filling/ selecting which of the existing images are already present in the project, using the Image input box of the Image View Attributes inspector. Then I can just set the titleView outlet of some navigationItem elsewhere in the same nib file, and voilà, my image is displayed at runtime exactly where I want I, when I want it. But now I create a second nib file for a second controller, and I really would like to display the same image in the same kind of setup. Problem is: I haven't figured out whether it is possible at all for nib file#2 to refer to any object inside nib file#1, No it is not. hence I have to either pay the memory cost of a duplicate object in the second nib file, Yes. as Ken told you, views can have only one superview. So, I've got the message, thank you, and I'm going to *programatically* share that view either in the app delegate or the root view controller, whichever way is cleanest. This will break. See above. And because you will try it you make clear that you did not understand the answer given by Ken. or forget about nib files entirely and do the whole wiring by hand with code, which kind of defeats the purpose of separate nib files in the first place. Why should you have to do that? You just need one titleView in every nib. A simple imageView takes up some bytes in memory. The image itself is shared anyway. You win nothing by trying to reuse that view. So ... is there a way to refer to NIB1.objA from NIB2.objB ? No. And there never will be, as it is impossible (see Ken’s very good explanation). It _is_ a beginners question and it was answered in detail. Bonus question: is it possible at all to refer to nib files (while staying within IB) outside of the main project directory? I tried variations on ./rsrc/mynib2 or rsrc/mynib2 in the NIB Name input field to no avail ... They have to be anywhere in the project. Just use the name, as they will be copied to Resources. I plainly understand that I can spread my NIB files all over the place (almost :-) if I go the coding route, but I'd rather do everything I can in IB if that's possible ... Yes, use nibs. Then just add that one image view and be done with it. atze ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Yes. The docs state:

Starts the event-driven parsing operation.
That means that -parse does not block. It runs in the event loop.
So the parser starts running and wants to talk to its delegate. But too bad -
you released it right after it started to work.
You have to retain it as long as the parsing takes. That is what the delegate
is for.

A view controller feeds the data (image of person) to its views.

If your view has to do a lot of work something is wrong. The view just draws information. It does not work on them. i'm just lost as to how an NSTimer and a looping set of code should be worked into these two classes.. should it be in the UIView? or the Controller? seems like it should be in the controller, but then really all the work has to be in the controller, since you can't even call the drawRect while in the controller, so what would you do in the UIView? any of that make sense?

Yes, basically. There is only going to be one in-memory object at a time
that represents the same managed object.
It certainly seems to be sensible, but I just wish someone could find such
documentation. I can't.
Every NSManagedObjectContext holds its own but unique copy of your object.
In the last few minutes here, I improved my demo to test an sqlite store as
well as an in-memory store, and also I setStalenessInterval to 0 and threw in
some -refreshObject:mergeChanges:NO and more saves. The only difference I
found was that, while the in-memory store fetches the same object that you
inserted, the sqlite store does not, although subsequent fetches return the
same object.
This is because the object in the sql-store needs a primary key. As long as it
was not saved it has a temporary key only. When saved it gets a persistent key.
After that it is identifiable by this and therefore you get alwas the same
object back.
I would have thought that your inserted object gets the persistent key set and
will therefore be the same object as the fetched ones. But I did not check your
code for a misconfiguration.
Can anyone guarantee this?
I would imagine that, even though it's not documented, Apple must realize
that if they were ever to change this behavior, it would probably break alot
of apps which have been relying on it without the designers realizing this.
Would Apple ever ever do anything like that?
No, you will always get the same object. Because this was why CoreData and EOF
where made for. Exactly this.

and produce:

What is wrong with Graham's example?

That's exactly how you implement a toggle action.
i meant it's clear that it's not possible with UIControlEvents... or
at least not simply so.
What is the second it's here if Graham's example is wrong?

Re: [iphone] Release Navigation View Controller Question
Am 18.01.2010 um 14:40 schrieb Philip Vallone:
Hi this is a follow up question on memory management. In my class
BrowseViewController, I have a UITableView and 2 NSMutableArrays.
@interface BrowseViewController : UIViewController UIActionSheetDelegate {
IBOutlet UITableView *tableView;

NSMutableArray *cfrTitleList;
}
@property(nonatomic, retain) UITableView *tableView;

Now the BrowseViewController has a few child Navigational controllers. This
allows the user to drill down. My question is, in the BrowseViewController.m
dealloc method, if I release the two NSMutableArrays, I receive the error
“EXC_BAD_ACCESS”.
Then you forgot to retain them when you should.
Show code where they are assigned if you can’t fix it.
If I don't release the NSMutableArrays, does this mean the
navigationController takes ownership of the NSMutableArrays?
No, it does not even know they exist. How should it?

However, your first example, would expand to:

Right.
and your second example expands to:

foo(x);

No to this.
I put a , not a ; between the statements. So at least my last example would

How should we know? You don’t show how your fetchedResultsController gets its
contents.
Am I able to add convenience methods to the classes that core data generates
for use as the entity classes if so can someone tell me what am I doing wrong?
Not without seeing code. Besides, I would not touch the generated classes. Use
a category instead.
Is there something stopping me from casting the result of
[fetchedResultsController objectAtIndexPath:indexPath] to a AdditiveEntity
which is a subclass of NSManagedObject anyway?
You can cast your objects even to a BOOL. But that will not make it a BOOL if
it is not a BOOL already.
@interface AdditiveEntity : NSManagedObject {
}
- (ADDITIVE_WARNING_TYPE)returnAdditiveWarningByType;
@end
So this is your header. Does your class have an implementation of that method?

Re: Autorotation for a subview
Eric,
1. Can’t you use autoresizingMask for all subviews? You can do pretty much
automagic with it. Just let your Button hang to the lower and right borders.
A view should not resize/reposition itself.
2. Don’t put the view of controller B into a view of controller A.
Why not presentModalViewController:animated:?
3. is a question from me to the knowing:
It seems that when didRotateFromInterfaceOrientation: is called, all views are
still in the old orientation. Is this correct? If so I will file a bug because
after it DID rotate the views should all have their new position / size.

it's removed itself from superview.
In regards to the NSNotification, I look at that as a learning opportunity

An NSNotification is not a sledgehammer. And letting interested listeners
know that a certain key moment in the lifetime of the application has been
reached, is not a mosquito. Indeed, this is why something like
UIApplicationDidFinishLaunchingNotification *is* a notification. Sometimes
the delegate or subclass instance is not the only interested party; the
moment where didRotateFromInterfaceOrientation: arrives might be such a
case.
Using a notification per se is not a sledgehammer.
Setting up your own view to post notifications for this situation, however,
almost certainly is (*insofar as it's possible to determine the OP's
requirements, given the confused problem description...*).
There is already a perfectly good mechanism for communicating changes about
a device's orientation through an object that's in the best place to respond
to such changes -- UIView*Controller*'s
willAnimateRotationToInterfaceOrientation... et al. methods.

Unthinkingly chasing interesting API is not a particularly useful

Per Henry's reply, you should properly describe what the task is you're

Hint; this:
- (IBAction) displayInfo:(id)sender {

UIViewAutoresizingFlexibleTopMargin
| UIViewAutoresizingFlexibleBottomMargin);
[self.view addSubview:myInfoView.view];
}
makes almost no sense.
Using a view controller to instantiate a view to add as a subview of
another view that is presumably managed by another view controller is not a
supported pattern. You're also ignoring basic memory management guidelines,
and will almost certainly be leaking both the view controller and its
accompanying view. Adding notifications to this scenario will not end
prettily.

Nope! First you alloc a dict in init:
segmentDict =[NSMutableDictionarydictionary];
[segmentDictretain];
And later you copy:
-(IBAction)initializeSectorSegmentData:(id) sender

segmentDict=[[MyDocumentgetSectorSegmentData:(id) sender] mutableCopy];

[segmentDictretain];
That are three retains on segmentDict - and only one release in dealloc.
- (void)awakeFromNib
{
segmentIndustryData=[[NSMutableArrayalloc] init];
[segmentIndustryDataretain];
// double init/retain
segmentDataController=[[NSArrayControlleralloc] init];
[segmentDataControllerretain];
// double init/retain
Anyway, even without retain, the table doesn't reload data.
I do not think naming is the issue, it is more of the good habit to have.
It makes clear what you have at hand - if you stick to it.
Really, I don’t want to offend you but the code you show is buggy and leaks. I
did not check the rest of your code after finding the release bugs.

Re: pls explain rotated iPhone coordinates to me
This seems wrong. When do you call this code? Usually it is just enough to set the springs of your scroll view in IB. Then, after rotation, refit your content. atze Am 15.12.2009 um 03:46 schrieb Matt Neuburg: I am not grasping how coordinates work in a rotated iPhone app, and I'm hoping someone will explain them. My goal is a scroll view consisting of two equal pages side by side with the iPhone sideways (landscape). I have accomplished this, but I don't understand how I did it; I used pure trial and error, and what works makes no sense to me. Here's what I did. The scroll view occupies the entire window (except for the status bar, of course). It has a view controller implemented so as to permit the autorotation, and the plist tells us to start up in landscape mode. And we do. So far so good. Now I populate the scroll view. I want its content to be double-wide, but I have to widen its *height* (svc is the scroll view's controller): CGRect f = svc.view.frame; CGSize sz = CGSizeMake(f.size.height * 2.0, f.size.width); // swap! ((UIScrollView*)svc.view).contentSize = sz; Now I place the first page content: CardController* cc = [[CardController alloc] initWithCard: [data objectAtIndex: 0]]; svc.view.frame = f; // don't swap!! [svc.view addSubview:cc.view]; Now I place the second page content: f.origin.x += f.size.height; // ??? height and width are swapped... // but x and y are not swapped? CardController* cc2 = [[CardController alloc] initWithCard: [data objectAtIndex: 1]]; cc2.view.frame = f; [svc.view addSubview: cc2.view]; This works great. But why? What on earth is going on here?

Controller does not set Loader's delegate to nil because it will get recycled anyway because Controller and no one else owns it. -BUT- NSURLConnection still holds on to Loader and sends it connectionDidFinish. This in turn makes Loader tell its own delegate that the loading is complete. Because Loader does not retain its delegate (avoiding retain-cycles) everything blows up.

Re: Core Data and +[NSExpression expressionForFunction:...]
Ron,
I am not sure if that works at all. I never fetched using methods that are not
part of the database as a qualifier. Your code has to be very slow because it
would need to fetch all Photos and then call distanceFromLatitude:longitude: on
each.
Why not qualify directly using a bounding rect?
latitude inLatitude - 0.1 latitude inLatitude + 0.1
longitude inLongitude - 0.1 longitude inLongitude + 0.1
The database can figure that out very fast.

Re: Performance
Am 16.11.2009 um 07:14 schrieb Chris Carson: The first class is the model that submits asynchronous bulk reads to the USB device. The callback for these reads copies the received data from the buffer asynchronous filled by the request and into an NSData object that is allocated and added to an NSArray. The buffer that the asynchronous request was using is recycled into a new asynchronous request. So the pool of buffers is allocated once and reused while the NSData objects are continuously allocated and deallocated (when released by the controller). The second class is the view that uses an NSTimer to call [self setNeedsDisplay:YES] 24 times per second. The drawRect: method requests data from the data source (the third, controller class) and draws it with OpenGL. Why? Only redraw if new data is available. The third class is the controller class that serves as a data source for the view. When the view calls the giveMeData: method, the controller class calls the buffer: method in the model class, which removes and returns the oldest NSData object in its NSArray. The controller then does some computations on it and passes it off to the view in a new NSData object. This sounds like you poll the model? Use a the controller as a delegate of the model to avoid polling. Make it event driven. The application runs pretty well, and running it through the Leaks instrument there are no leaks except for 16-bytes when the application is first starting caused by IOUSBLib. However, looking at it in the Activity Monitor, the real memory used starts off at 25 MB and steadily grows to 250+ MB while the virtual memory starts off at about the same and steadily grows to about the same or sometimes close to 500MB, over the course of several minutes. This especially happens if I don't move the mouse for a while, or don't have the application in focus. As soon as a move the mouse or bring the application into focus, it's as if an autorelease pool is drained and the memory drops back down to 30-40MB real and 30-40MB virtual. This is annoying since the application hangs for 5 seconds or so when this memory draining is occurring. Has anyone dealt with this before? Any ideas on what could be causing this and how to work around it? This is exactly the case. The run loop does nothing if it has no input to handle. Alloc your own autorelease pools at places that look like they would alloc some amount of autoreleased objects. Loops, the method you fire with your timer! and the filling of the array. I do have a comment in my code (fired by a timer) that looks like this: // NSView's getRectsBeingDrawn:count calls [NSMutableData dataWithLength] // those build up if we don’t get them away faster than the runloop (@List: Should I file a radar?) Another related question: The number of asynchronous requests that the driver submits at once and the maximum number of objects in the NSArray are set to some constant. Now in theory, the requests should be added and drained simultaneously (i.e. by separate threads), but if I make this constant larger, I notice a greater delay between when data entering the USB device and being plotted. It's as if the asynchronous requests are being filled and added to the NSArray all in a group, and then drained by the view all in a group... maybe? Is this something subtle from the way run loops work? Is the USB asynchronous bulk read run loop source on the same thread as the view class's drawRect method? That could be, depending on your code.

I don’t know if CoreData can do that as well. But why don’t you want to save? If you just want your objects in memory, why use CoreData at all? atze ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: NSDate / NSXMLParser
The parser CAN parse the timezone and adjust the date accordingly. To parse this date: 20091021T121942+0200 I use this format: MMdd'T'HHmmssZZZ and it works fine. The only thing you need is to find the right timezone format string. Yours might be '-'MM'-'dd'T'HH':'mm':'ssZ Not sure if you need to '' the : and - And I really don’t know if the Z at the end of your date is tr35-6 compatible. Have a look at http://unicode.org/reports/tr35/tr35-6.html#Date_Format_Patterns for your format. atze ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Handling projects with several XIBs
Am 02.11.2009 um 11:55 schrieb Tobias Jordan: The problem I am currently having is that when updating the interface I have to a) make my changes to every localization (en, ge, fr, jp, etc.) or b) re-create all of the localizations which isn't that easy to handle since I am not the one translating everything. That is how you do it for localized nibs. Both ways are really time-consuming and I was wondering if there's a way to define some placeholders for strings and other resources such as images or sth. like that. Alternatively you can use just one nib and replace the values using NSLocalizedString(). But you have to watch out for the lengths and sizes in different languages. What's the most fastest and efficient way? It depends on what you goal is. a b) are best if you want to have nice sized buttons in all languages NSLocalizedString is easier to implement and to translate but the final look might get gruesome. atze ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Displaying a view modally (iPhone)
Mike, you need a view that has the size of the window to cover it completely. Otherwise touches will go down the responder chain and reach other views. What happens while you show the spinner? If you load data from the net show the UIApps spinner at the top. atze Am 21.10.2009 um 02:26 schrieb Mike Manzano: Hi, I'd like to display a busy indicator view (HUD) regardless of whatever view is currently at the top of the view stack. I'd also like this view to display modally so that the user interface beneath it is dead to touch events. This is like Tweetie 2's HUD that appears when you've successfully posted something to Instapaper, with the difference that the UI underneath it wouldn't accept events as they do in Tweetie 2. I'd also like to have some control over animating the HUD onto and off of the screen. My current thinking is to find the topmost view controller somehow and send it presentModalViewController:animated:. However, I don't know how much control over animation I'd get with that method as the built-in animation styles sort of assume a full screen view. Also, I've never tried to use this method with a view that's smaller than the screen size. Another thought is to just add the view to the root view and bring it to the top (this however won't make the view modal as the views below will still respond to touch events). Can anyone tell me if I'm thinking along the right directions? I'd like to have some confirmation before I invest a bunch of time only to find out it's the wrong method. Thanks, Mike Manzano mike (at) instantvoodoomagic (dot) com http://instantvoodoomagic.com @instantvoodoo Oh BTW, the first reply that gets me closer to a solution gets a free promo code for Newsie (http://instantvoodoomagic.com/newsie), the Google Reader client for iPhone/iPod touch that I just released ;) ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
