Re: NSFileManager thread safety?
Why do you think this is a thread safety issue? The -applicationShouldTerminate: delegate method is called on the main thread. It looks more like your path (as retrieved from -tempDirPath) is not a valid object. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

NSFileManager thread safety?
The following code snippet works fine from my main thread.
NSFileManager *tempFileManager = [[NSFileManager alloc] init];
NSString *path= [self tempDirPath];
if(![tempFileManager removeItemAtPath: path error: nil]) {
NSLog(@"failed to remove temp files");
}
[tempFileManager release];
But from within
-(NSApplicationTerminateReply)applicationShouldTerminate:(NSApplication
*)sender
or other delegate methods, it gets my EXC_BAD_ACCESS on the
removeItemAtPath call
- any suggestions? I thought NSFileManager was supposed to be
thread-safe in 10.5 and 10.6?
If this is a thread safety issue (and given the code works in the
main thread, I'm not sure what other issues might be the problem),
what is the solution to force calling it from the main thread?
Thanks In Advance
David

If you're sure that no other forked process will exit before the process spawned by AEWP (generally, a reasonable assumption), you can simply wait().

Re: Advice On Subclass vs. Delegate
Let me try character-art to illustrate the issue (forgive the top-post): +---+ Title: | |<= splits on spaces only, counts dups +---+ Label: word count Label:dup count +---+ Keywords: | |<= splits on comma with optional +---+ whitespace, counts dups Label: word count Label:dup count NSTextField | DuplicateCounterTextField So, in IB, I set the class of the two fields to DuplicateCounterTextField and the delegate to WindowController. DuplicateCounterTextField implements: - textDidChange:notification; - textView:view completions:completions forPartialWordRange:range indexOfSelectedItem:index In the delegate class's awakeFromNib, I set the splitter string, which works fine. So, WindowController understands that there is an outlet called title and one called keywords, and that they are connected to the corresponding controls on the form. However, DuplicateCounterTextField is deliberately stupid. The question is, should an instance of DuplicateCounterTextField call a (to be implemented) delegate method wordCountDidChange:notification to allow the two labels to be updated by WindowController, thus tying the whole thing together or is there a better way. Clearly, this is a trivial example, but I'm trying to understand desirable patterns that can last as an application grows.

Transparent layer-backed views
Hello, I'm trying to perform some simple animations using CA layers on transparent window and corresponding view. The problem I have is that every time I turn on the layer backing (either through wantsLayer in code, or with IB) the view stops being transparent. I've tried setting layer's backgroundColor to something with low alpha and few other rather obvious approaches, but it looks to me that I'm missing something. To illustrate the problem better, let's just use sample Round Transparent Window project from Apple (http://developer.apple.com/Mac/library/samplecode/RoundTransparentWindow/index.html ). By default it looks like this: http://slonce.com/no-layer.png But with layer added (just this single line in awakeFromNib), the transparency goes away: http://slonce.com/with-layer.png Could anyone please give me some hints on this?

Question about IB, filterPredicate, and bindings
Hello, list. I am a hack programmer, so forgive what is probably an obvious question. I'm working on a core data document based app that uses bindings I've created in IB to control a master / detail interface. Briefly, in XCode's xcdatamodel, there is a Person entity with a name (String) and employee (Bool). I have another entity, Transaction, which has an amount (Decimal) and an operator (Person Relationship). So far, so good. Everything is nicely working with bindings. However, I only want the operator pop-up to display Person entities for which employee == 1 (the predicate that I can build in the xcdatamodel fetch request). I would have thought that, in IB, I should be able to choose the pop- up button binding, set the Content binding to the Person array controller, set the controller key to filterPredicate, and choose the keyPath to be the pre-made fetch called getEmployees that I created in the xcdatamodel. It seems like that would simply limit the content to records that fit the predicate. Needless to say, this doesn't work, since at compile time, the console shows this: 2009-11-14 09:47:15.190 iCredit v0.1[7370:a0f] Binding contentValues of object ignored: Key path (currently bound as arrangedObjects.firstName) needs to have the content key path (filterPredicate.getEmployees) as prefix What should I have done, or can this be achieved with IB at all? I'm not opposed to writing the code to populate the NSPopUpButton object by hand, but bindings seem so right for this purpose that I can't seem to get past this hangup.

Performance
Hi all, A performance related question: I've written a Cocoa app that continuously reads data from a USB device and plots it on a graph. It consists of three of my own classes. 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. 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. 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? 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? My apologies for the length of this post and if the USB stuff isn't strictly Cocoa related, but since it's so intertwined with Cocoa classes, I figured this was the best place to ask. Advice is much appreciated. Please CC me on replies. Chris ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: CALayer Transitions
I had actually tried using that delegate method. It gets called a lot
because the same controller is delegate to many layers (for drawing). Of
course, I filter it for the my "content" layer. As you noted, using
"sublayers" also triggers for other sublayers and I may have to use your
flag method to prevent this.
What I don't understand, is that, according to the core animation guide,
kCATransition seems to be what I want for a key instead of "sublayers". The
guide says this is triggered by "replaceSublayer: with:". However, stepping
it through, I never see this key come through the delegate.

To elaborate, the purpose of the key in -addAnimation:forKey: is so
that you can go back and refer to the animation later without having
to store it in some external data structure. Instead, it's hanging
right on the layer you attached it to. It's unfortunate that Core
Animation suffers from such a conflict of terminology here. They
really should have picked something else ("tag"?) to describe "handle
by which you can refer to an animation you previously attached to this
thing."

This is probably the easiest if you already have a delegate. If
you're doing a one-off animation here, you could get away with
aLayer.actions = [NSArray arrayWithObject:anAnimation];

Your understanding is likely wrong. :) addAnimation:forKey: on a layer
triggers the animation then and there. Look at the examples in the Animation
section of the Core Animation Programming Guide.
That, however, isn't what you want. You want the action of replacing
sublayer A with sublayer B to trigger the animation. For that, look at the
Actions section of the Core Animation Programming Guide.
For my money, the easiest way to set this up is to make self your
contentLayer's delegate and implement actionForLayer:forKey:. So, assuming
the delegation is already set up:
-(void)transitionFrom:(CALayer*)A to:(CALayer*)B {
[[window.contentView layer] replaceSublayer:A with:B];
}
- (id)actionForLayer:(CALayer *)theLayer
forKey:(NSString *)theKey {
if ([theKey isEqualToString:@"sublayers"]) {
CATransition* trans = [CATransition animation];
trans.type = kCATransitionPush;
trans.subtype = kCATransitionFromLeft;
trans.speed = 0.5;
return trans;
}
return [NSNull null]; // or whatever
}
To be cleverer about when to trigger the animation and when not, just raise
an ivar flag in self. For example, you might like to animate when certain
sublayers are added but not others. So transitionFrom would raise a flag and
actionForLayer could check that flag (in addition to checking the key).
That's why I like this approach: it's so flexible. However, there are other
ways to do it.
By the way, there is an example almost *exactly* like this in the Actions
section of the Core Animation Programming Guide. m.

Synchronization & Core Data
Good evening to everyone, I'm in a (extensive) planning stage of a project and an issue of synchronization is forcing itself on me, I asked a question this morning about a networking side of things, and I got some info from nice people here about MYNetwork: http://bitbucket.org/snej/mynetwork/wiki/Home (I want to be able to sync data between Desktops and iPhones on a local network). However, now I'm wondering how should I organize / store my data. I want to use CoreData and I could, easily. I probably won't even have to write a lot of code as I'm storing numbers, strings, and dates. Most of the behavior I need is free. But how would I sync core data stores between devices? Only info I could find was this post: http://forums.pragprog.com/forums/90/topics/3201. Perhaps someone has some experience with this? Should I do, as the post says, and create "date modified" attribute and write my own logic? Or is it possible, after all, to get some behavior for free from core data framework?

Authorization Samples for Cocoa?
Hello. I need a little helper tool to run under privileges and got it to work with help from the "BLAuthentication" class. However, I'd like to put up a personalized message when the security server requests the user to enter an admin password. The BLAuthentication class uses "AuthorizationExecuteWithPrivileges" which doesn't seem to allow to pass a description like "AuthorizationRightSet" seems to allow. I've searched for some samples but they are all very outdated (from 2005 (AuthForAll) and 2007 (BetterAuthorizationSample)) and are way too complex to understand in like one hour. I can't imagine that all that crap hasn't been encapsulated under some Objective-C classes. Anyone has any idea or pointer to something basic I don't need to take a few hours to figure it out? I'm not interested in a sample with an array of functions that perform an array of things, just a plain, simple example would do.

Would help me a lot, since I wouldn't have to force- kill the whole system (forced shutdown...). Any ideas? You could use the alarm() syscall. This will schedule a SIGALARM to be sent to your process in some number of seconds. If you don't have a signal handler set up for that signal (and by default, you don't), then your program will be terminated. Just put a line like "alarm(10);" near the beginning of main(). (If you have another machine available, even a non-Mac, then using ssh to log in and kill the process is probably the easiest route, as Jens Alfke suggests.)

Re: How can a plug-in bundle get access to its own resources?
As has been pointed out several times, it's a really bad idea to have the same-named class in multiple plugins. The Objective-C runtime will load the first class instance it finds (in your case, in the first- loaded plugin). For all other plugins, when the class is referenced, that first class instance is used, so calling [NSBundle bundleForClass: [self class]] will cause it to return the bundle for that first plugin, no matter which plugin is asking. This answers your question about code knowing its containing bundle. You made an assumption about where the plug-in's code was loaded that turned out to be incorrect. If you want to use the same class code for each plug-in, I would suggest that you use a #define to rename the plug-in class at build time, and add a per-target definition containing a unique class name. Then your common class would be renamed automatically for each target. If you have to specify the plugin class in, say, your Info.plist, you could use the same build definition. @interface PLUGIN_CLASS_NAME ... @end @implementation PLUGIN_CLASS_NAME ... @end The benefit of going with this model is that you still maintain a single code base for all of your plugins, even though the class is renamed on a per-plugin basis; you eliminate the "which plugin am I" problem you're running into now; and you don't have to worry about having an older plugin version that happens to load before a newer version, thus forcing all the newer plug-ins to use the older plug-in code.

Example of categorized lists in a Mail-type interface
Hi all, I would appreciate it if someone could point me at an example that I could use as the basis for building a categorized list similar to the mail folders display in Mail. I have a data model that has an entity called category and another called item. These have a one to many relationship (an item is in just one category, while a category can have many items). I want to have a list of categories in the left panel, with a disclosure arrow to open up for a list of items in that category. Selecting each item shows the detail to the right. As with Mail the category titles should not be selectable, but only open or close via the arrow. BTW I am only looking for one level of hierarchy below the category, so it is different from Mail in that respect. I'm probably missing something obvious but I can't see how to start with building or coding this. Anyway, I'm not looking for a complete solution, obviously, but some pointers or examples to use as a starting point. Thanks for any guidance you can offer.

The reason often given (to which I don't personally subscribe) is that the accessor could be overridden in a subclass, and therefore do things that aren't appropriate (i.e. they could assume something about the already-dealloc'ed or not-yet-init'ed portions of the subclass). -- Clark S.
