Re: creating an NSSearchField subclass like Safari

Older version of spotlight importer plugin still seen by mdimport -L
I have already filed a bug report on this ( rdar://7602076 ) and am mostly wondering if there is any possible workaround while keeping the spotlight importer in the application bundle. Basically what is going on is that there are two different versions of the same application. Version 1.0 of the application has version 1.0 of the spotlight importer. Version 2.0 of the application has version 2.0 of the spotlight importer. As I understand it, Mac OS X should only try to use the newest version of the spotlight importer and yet both will show up when I do a mdimport -L - I am assuming this is a problem. Both spotlight importers have the same CFBundleIdentifier and denote their version with CFBundleVersion. I could, of course, install the spotlight importer into /Library and make sure that only the latest version is there, but I like keeping them with the application. Thoughts?

Re: Versioning / increasing build number
Just one more thought:
you could have a shell script build phase that runs whatever tool you're using
to bump the build number and only run this when building the deployment
configuration (e.g. by checking ${CONFIGURATION} in your script, or by
activating the Run script only when installing checkbox in the script build
phase, which seems to have the side effect of only executing during the
deployment builds).
That way, your debug builds (during your development cycles) won't proliferate
the build numbers, but any time you run a deployment build, the build number
gets bumped...

Re: Versioning / increasing build number
Another option, which I posted as a comment on my site (linked to previously),
is to move Info.plist to Info.template.plist, and then use the build number
script to generate the Info.plist that the compiler will actually use. That
way you can set an ignore on the generated Info.plist file (if you're using a
source control system), but still have the original template plist in the
repository.

Simple Cocoa App Not Working
I am trying to learn Cocoa and wrote a simple app using the MVC pattern. The
view controls two text fields, the controller receives events from a single
button, and the model receives the value entered into the first text field, and
then requests the view to display that value in the second text field. I used
IB to construct the UI and connect the view object with the text fields, and
made the controller the target for the button. The build is successful, but
the value from the first text field is not copied into the second. A printf
shows the integer value from the first text field is zero. Here are the short
files. Thanks in advance.

You're actually breaking the MVC pattern here. The model should not have a
reference to the View - that's the controller's business. The model should be
completely agnostic of how it's displayed.
I used IB to construct the UI and connect the view object with the text
fields, and made the controller the target for the button. The build is
successful, but the value from the first text field is not copied into the
second. A printf shows the integer value from the first text field is zero.
Here are the short files. Thanks in advance.
At which point in your code did you print the value? What was in the text field
when you saw zero being printed? Set a breakpoint in your viewAction and print
the value of the text field. What does that tell you?
[snip]
- (void) showValue;
That's the method that should be in the controller, not in the model. Also, the
View instance variable should be in the controller.
@implementation Model
- (id) init {
self = [super init];
view = [[View alloc] init];
return self;
}
@synthesize value;
- (void) showValue {
self.value = [view getFieldValue];
[view setResult:self.value];
}
@end
You're missing a dealloc method - you'll leak view. Also, your init method
isn't according to the standard. You should always check if [super init]
returns nil. Check the Cocoa Fundamentals Guide. Same for your other classes.
--
#import Cocoa/Cocoa.h
@interface View : NSObject {
IBOutlet NSTextField* number;
IBOutlet NSTextField* result;
}
Pet peeve: don't name text fields with names that suggest they're model
objects. Something like numberField would be less confusing to others.
- (int) getFieldValue;
- (void) setResult: (int) value;
@end
--
#import View.h
@implementation View
- (int) getFieldValue {
return [number intValue];
}
- (void) setResult: (int) value {
[result setIntValue:value];
}
@end
--
#import Cocoa/Cocoa.h
#import Model.h
@interface Controller : NSObject {
Model* model;
}
This is where your View instance variable goes.
- (IBAction) viewAction: (id) sender;
@end
--
#import Controller.h
@implementation Controller
- (id) init {
self = [super init];
model = [[Model alloc] init];
return self;
}
- (IBAction) viewAction: (id) sender {
[model showValue];
}
And in this method, you ask the model for its value and you have the view
display it.
Welcome to Cocoa, and good luck!

Re: NSXML and
Great, many thanks for the reply, and for the location of the information in the XML docs, that's very helpful.

Cocoa+OpenGL app crashes iMac
I have a multithreaded Cocoa+OpenGL app that can reliably bring down OSX. I am using the latest released/patched version of OSX, all updates have been downloaded and applied. The application has a thread that displays video frames as OpenGL textures. When I resize the associated window, it crashes OSX in various ways. Sometimes OSX just hangs. Sometimes the whole screen goes black. Sometimes I get psychedelic colors displayed outside my application, for instance when I click the OSX dropdown menu at the top left corner of the screen, it displays with blasts of colors splayed across the screen. When OSX doesn't completely die and I try to remotely log in and kill my process with a -9 signal, OSX refuses to kill it. I've tried using Quartz Debug, that brings down OSX particularly hard. When OSX doesn't hang, the graphics device driver state seems to get corrupted, even when my application has finished running, I get the weird psychedelic colors in OSX menus and programs. Now, I'm sure I've got a bug in my program--but nothing I'm doing should make OSX behave this way. Fundamentally this is an OSX bug. In any case it's difficult to find the bug when OSX comes crashing down. Any tips?

Generally the concept is test for what you need because you don't know what the configuration will be. Two examples: 1) Someone adds a GPS unit to an iPod Touch that provides Compass heading information. Should you treat the device like an iPod or an iPhone? 2) Should removes the Camera from an iPhone. Should you treat it as an iPod or iPhone?

I would expect that it's done using a private custom subclass of NSScroller -
the standard control doesn't support this.
It's not too hard though. I did it. Here's some code I wrote a few years ago. I
might do it a little differently now, but it works fine and at quick glance it
generally looks ok.

Finder style dialog to resolve NSURL bookmark data for missing file?
I am using the new NSURL bookmark data API introduced in OS X 10.6 to store an alias to a file system resource. When I use +[NSURL URLByResolvingBookmarkData:options:relativeToURL:bookmarkDataIsStale:error:] to resolve the bookmark data, I get nil if the file no longer exists (or has been moved to a different volume, etc.). Since I am not passing NSURLBookmarkResolutionWithoutUI in the bookmark resolution options, I expected to get a dialog, like that shown by the Finder when you open an alias file that no longer resolves (i.e. a dialog to cancel, fix the alias, etc...). Is there a way to have NSURL automatically prompt to reconnect/resolve the broken bookmark data? The bookmark data is created via: NSError *err NSData *bookmarkData = [myFileURL bookmarkDataWithOptions:NSURLBookmarkCreationSuitableForBookmarkFile includingResourceValuesForKeys:nil relativeToURL:nil error:err]; though I get the same outcome if I use 0 for the options instead of NSURLBookmarkCreationSuitableForBookmarkFile. I attempt to resolve the same bookmarkData via: BOOL stale; NSError *err NSURL *resolvedURL = [NSURL URLByResolvingBookmarkData:bookmarkData options:0 relativeToURL:nil bookmarkDataIsStale:stale error:err]; Going through the dance of writing the bookmark data to a finder alias file and then resolving the URL by reading bookmark data from that file followed by the above method does not produce the desired UI result either (though opening the alias file in the Finder does produce the desired UI dialog).

Cocoaheads Lake Forest (92630) meeting TOMORROW, Wed 2/10/2010 at 7 pm on whiteboarding a Cocoa Touch application
CocoaHeads Lake Forest will be meeting on the second Wednesday of the month. We will be meeting at the Orange County Public Library (El Toro) community room, 24672 Raymond Way, Lake Forest, CA 92630 Please join us from 7pm to 9pm on Wednesday, 2/10. We are going to be whiteboarding the design of an ipad/iphone application for tracking DnD power cards. (Other options are also on the table...) Our goal is to spec out the features based on the current, non-NDA iphone SDK, along with some educated guesses as to how it will change on the iPad. Our desired end product is a fairly detailed look, feel, and design. (We are going low tech - not even a projector!) Future sessions will build data models, create code, and generate a UI.

Re: Running NSURLConnection from within an NSOperation?
On 2010 Feb 09, at 14:10, Greg Reichow wrote: I'm trying to run an NSURLConnection from an NSOperation. Apparently, it won't run. I know that NSURLConnection need a run loop. Does that mean I'll have to setup some kind of NSTime in my NSOperation and then call my run loop at regular intervals? Try using the synchronous version of NSURLConnection since you are launching it from within a NSOperation already- + (NSData *)sendSynchronousRequest:(NSURLRequest *)request returningResponse:(NSURLResponse**)response error:(NSError **)error Indeed sendSynchronousRequest: will work for a quick hack to talk to, say, your own server, but if you hope to some day have a real app which predictably handles real-world corner cases, well, let me quote what was told to me once: The NSErrors that you get from -sendSynchronousRequest: are not documented. For example, if you give it a wrong username/password combination, you get NSURLErrorUserCancelledAuthentication = -1012. Apparently this is an implementation detail, that when it receives an authentication challenge, it cancels. You're leaving the policy decisions to Apple instead of making them yourself, and since they are not documented, Apple may change them at any time. It is true that the alternative asynchronous methods require a run loop. (Don't use a timer). ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Large queue of messages for another app
I have a main app and a sub-app background process (both Cocoa). The main app needs to send the sub-app a bunch of files to process... Anywhere from one to hundreds. The main app has a list of paths to process in an NSArray. In my testing with NSDistributedNotifcationCenter, it handles up to about 30... After that it starts to lose some. What are better options? 1) Apple Events... These are messy but I'd go there if it'd not have lost events. 2) Write the NSArray to a file, then let the subapp just read from this file and process them one at a time. TI could notify the subapp via a DistributedNotifactation or it could just keep poling a private folder every so often (yuck). The only problem I see with this is how can I cancel one or more files from the queue since I don't think it's a good idea to have both apps writing to the same file. 3) Distributed Objects? Not sure how this would work - how do my app find each other? If I could do: [remoteApp processDict:myDict]; // dict has a @Path key with a file path Thaoughts?
