ImageIO on iPhone
Hello, I want to use ImageIO on the iPhone. However, the ApplicationServices framework does not show up in the list, when i do the Add - Existing Framework command. When i just add the line #import ApplicationServices/ApplicationServices.h I get some errors like 'CFXMLTreeRef' has not been declared (full list below). I added the CoreFoundation framework (where CFXMLTreeRef is defined), but no success. I want to use ImageIO from C++, that should be possible, shouldn't it? Can someone help me?

NSData category
I am really really irritated. Got an iPhone project. Got quite some categories with additions to the standard APIs. All good. Just the darn NSData refuses to accept the category ... and I have no clue why. It's as simple as @interface NSData (NSDataAdditions) + (id) dataWithHexString:(NSString*)theHex; - (NSString*) hexString; @end I've tried prefixing the methods, I've use a more exotic category name than just NSDataAdditions. Whatever I am trying ... the class/object does not have the selectors. Even something simple as NSData *data = [NSData data]; //[NSData dataWithHexString:@aabbccdd]; NSLog(@@%, [data hexString]); gives me -[NSConcreteData hexString]: unrecognized selector sent to instance ... Why NSConcreteData? Does it create a different object under the hood so my category is not applicable? I've used NSData categories before and the worked just fine. Is there a way in gdb to look at the categories/method lists easily? Or should they selectors show up through class_copyMethodList? Could really use some ideas here. cheers -- Torsten ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: NSData category
Why NSConcreteData? Does it create a different object under the hood Yes, NSData is a class cluster (see Google). NSString, NSArray and NSDictionary are too, and no doubt others. But I don't see why you shouldn't put a category on NSConcreteData, other than the fact that the sand might shift under your feet in a future release of the OS.

Just locate the framework in the Finder and drag its icon into your project. You may need to edit the target build settings to add /System/Library/PrivateFrameworks/ to the framework search path.

But do keep in mind that: • Private frameworks can change without warning even in minor OS updates, possibly breaking your app. (Weak-linking is advisable.) • One common reason for Apple not to make an API public is that is isn't quite baked yet, i.e. may not work quite correctly or may have been tested only in the specific ways it's used by Apple software. • You're not going to be able to ask for help here or any other Apple forum.

NSPredicate Binding Problem
In a window displaying a widget object I am using an outlineview bound to an NSTreeController as master view. When I notice the OV selection change via outlineViewSelectionDidChange I filter a tableview bound to an NSArrayController in one of two ways like so... Method 1 :: use setFilterPredicate on the NSArrayController and set to a new NSPredicate Method 2 :: In IB bind the NSArrayController's Filter Predicate to a property called myPredicate and use KVC to set a new NSPredicate Either of these methods work fine - the tableview's content filters fine. The problem I am having is that when I load a new widget, thus releasing the current widget view from the window, along with it's NSViewController, I get the error... Cannot remove an observer _NSArrayControllerExtensions 0x12c8b30 for the key path... I have googled and found this is typically to do with non KVO compliant models. I have checked and rechecked my models and made sure that all properties are compliant with KVO. While debugging I removed resetting the NSPredicate in outlineViewSelectionDidChange and instead just set it once in awakFromNib and the issue goes away. This brings me to the conclusion that somehow resetting the NSPredicate for the NSArrayController is not allowed. How should I go about filtering my tableview? Should it be okay to reset the NSArrayController's filterPredicate... ie is there something else going on?

Re: Question about zipping files
On 2/15/10 4:50 PM, Gideon King said: Thanks for the suggestion. Have not encountered Scripting Bridge before and have very little experience or understanding of AppleScript and no knowledge of Apple Events or what they do. I had a vague notion that Apple Events were pretty much old technology from before OSX, but now I see that it appears that it's the foundation of AppleScript. I guess I should take time to look into these technologies sometime (I come from a NextStep/OpenStep/WebObjects background)... AppleEvents date from System 7, so yeah, they're pretty old. But that should not automatically disqualify them. UNIX and NeXTStep are old too. :) Is there any particular reason you say to stay away from NSTask? I only meant that it's generally preferable to use an API when you can. ex: don't copy files using NSTask and 'cp', because NSWorkspace can copy files. Scripting Bridge seems like an interesting option, but after having generated the headers for Finder, I could not see a command there for compressing files. I guess it's not scriptable. The Finder is scriptable, but not every command can be scripted. I looked quickly with AppleScript Editor, and indeed Finder does not seem to expose 'compress'. Oh well. I'd file a bug asking that NSWorkspaceCompressOperation be implemented. -- Sean McBride, B.

Re: Validation error after setting the value of a boolean attribute
Boolean attributes in Core Data are not actually of type BOOL but rather NSNumber. Thus, your NO value is interpreted as nil (since nil == 0 == NO) and you're setting your attribute to nil. If the attribute is required, then nil is not a valid value, and you will get a validation error. Next time, if you look at the header of your file, it tells you what types you should use as arguments to methods, and what types to expect as return values.

Re: Perform additional action when window receives any mouse- or keyDown
Uh, if I understand what the op wants to do correctly, overriding - [NSWindow mouseDown:] isn't going to do it. If the user clicks inside a view that overrides -mouseDown: (and friends -rightMouseDown: and -otherMouseDown:), there's no guarantee that your window's override will get called.

Re: Refresh com.apple.symbolichotkeys.plist
Is there any way to cause the system to re-read com.apple.symbolichotkeys.plist.plist in Cocoa (or anywhere else)? I want to programmatically change a shortcut (which is no problem), but I want it to take effect immediately. System Preferences obviously signals the system to do this - does anyone know how it does that?

Puppeting/Automating one application from another?
Hi, I'm trying to figure out the general feasibility of the following task. Imagine I have two separate applications, running side by side. Is it possible to take all of the mouse/keyboard inputs that are going into one of these applications, and send them to the other in a way that would allow me to 'control' the other app from the events generated in the first? I took a few steps to begin creating an infrastructure to support this, but then became concerned that I'd soon have issues with focusing, like if pressing buttons in the 'puppeted' application would take away the focus in the application sending the events. Does anyone know if something like this is possible? If so, does anyone know of any applications that do this, or have any pointers that could help me with this?

Bindings: NSArrayController gets a new but equal array, pushes back to model
This is a resolution of my message posted 2010 Jan 02, subject: Bindings/Core Data: Undesired Discovery of a Mythical Deep Observer I'm posting this because, after rewriting the whole thing and giving it some more thought, I believe I have an explanation, which archive-searchers might find interesting. Summary: If an NSArrayController with 'contentArray' bound to a data model receives from the data model a new array which is equal to but a different pointer value than the array it currently has, it will push the new array back through the setter of the data model. I'm working on a Core Data project. Some to-many properties are displayed in tables, and these objects in turn have their own attributes which are displayed in the columns, bound to array controllers' -arrangedObjects.xxx, etc. Pretty standard stuff... DEPARTMENT's EMPLOYEES NameRank Salary --- -- Fat Cat 3 200 except that I have subclassed NSManagedObject and added 'index' attributes so that I can treat the sets as arrays, providing methods, for example -(NSArray*)employeesOrdered, -(Employee*)newEmployeeAtIndex:, etc. All this works OK, except in a few of my columns I notice that, taking the above example, if user edits the table to change, say, the 'rank' of Fat Cat, after sending setRank:, the *Department* gets a -setEmployeesOrdered: message, with an NSArray argument which is a different pointer value but otherwise equal to the existing employeesOrdered array; it contains the same single object with the same pointer value. This does no harm to the data model of course; the only reason I noticed it is because in some cases it overwrites and thus screws up my undo action names which are driven by custom setters. In real life, -setEmployeesOrdered: is actually -setExternalizersOrdered and is #9 in the call stack below. To fix the problem, in this setter I simply first check for array equality and return if no change. Looking at the calls lower down, it appears to be fulfilling the binding on the array controller which causes this unnecessary message. Of course, I do have an array controller with contentArray bound to 'externalizersOrdered'. Also, it makes sense that there would be different pointer values of externalizersOrdered floating around since the getter computes it from the underlying set. See code at the end. I've decided that, apparently what's happening is that when when the array controller notices that a bound (by a table column) to attribute is changed, it asks the data model for -externalizersOrdered, sees that it gets a different array, but does not bother to check and see that the new array, although a different pointer value, is equal to the old array. Probably it only keeps a reference. And then due to some quirk in bindings it says, Oh, I better push this new array to the data model's setter (even though it just got it from the data model). If anyone has read this far and has a better explanation, let us know. #0 0x00122961 in -[Bkmslf setUndoActionNameForAction:object:objectKey:updatedKey:count:] at Bkmslf.m:2928 #1 0x0001fd71 in -[Bookshig mikeAshObserveValueForKeyPath:ofObject:change:userInfo:] at Bookshig.m:1789 #2 0x000ff452 in -[MAKVObservation observeValueForKeyPath:ofObject:change:context:] at MAKVONotificationCenter.m:98 #3 0x002d6208 in NSKeyValueNotifyObserver #4 0x002d5ca7 in NSKeyValueDidChange #5 0x002ba6d0 in -[NSObject(NSKeyValueObserverNotification) didChangeValueForKey:] #6 0x01baa375 in -[NSManagedObject didChangeValueForKey:] #7 0x0006e3fb in -[Ixternalizer setIndex:] at Ixternalizer.m:351 #8 0x000b6d93 in -[SSYManagedObject setWithIndexesArray:forSetKey:] at SSYManagedObject.m:231 #9 0x0001d7f5 in -[Bookshig setExternalizersOrdered:] at Bookshig.m:1233 #10 0x002dec99 in _NSSetObjectValueAndNotify #11 0x01ba726a in -[NSManagedObject setValue:forKey:] #12 0x002eead3 in -[NSObject(NSKeyValueCoding) setValue:forKeyPath:] #13 0x002eeaaf in -[NSObject(NSKeyValueCoding) setValue:forKeyPath:] #14 0x002eeaaf in -[NSObject(NSKeyValueCoding) setValue:forKeyPath:] #15 0x0078f0d6 in -[NSBinder _setValue:forKeyPath:ofObject:mode:validateImmediately:raisesForNotApplicableKeys:error:] #16 0x0078eeb0 in -[NSBinder setValue:forBinding:error:] #17 0x00b14745 in -[NSObjectDetailBinder setMasterObjectRelationship:refreshDetailContent:] #18 0x00b1461d in -[NSObjectDetailBinder noteContentValueHasChanged] #19 0x008f27ac in -[NSArrayController _setMultipleValue:forKeyPath:atIndex:] #20 0x0078f211 in -[NSBinder _setValue:forKeyPath:ofObject:mode:validateImmediately:raisesForNotApplicableKeys:error:] #21 0x00903832 in -[NSBinder setValue:forBinding:atIndex:error:] #22 0x0078ed3d in -[_NSValueBinderPlugin applyObjectValue:forBinding:operation:needToRunAlert:error:] #23 0x00ca9a4d in -[NSValueBinder
Re: Puppeting/Automating one application from another?

Is it possible to take all of the mouse/keyboard inputs that are going into one of these applications, and send them to the other in a way that would allow me to 'control' the other app from the events generated in the first? I took a few steps to begin creating an infrastructure to support this, but then became concerned that I'd soon have issues with focusing, like if pressing buttons in the 'puppeted' application would take away the focus in the application sending the events. Does anyone know if something like this is possible? If so, does anyone know of any applications that do this, or have any pointers that could help me with this? The first thought off the top of my head was NSDistributedNotificationCenter. Should be possible to flange up a mini-application to test the idea . . .

Dynamically populate a popup menu
Is there any way to dynamically populate a popup menu on the fly (as it is exposed)? For example, a popup menu that displayed the harddisk hierarchy would need this sort of thing - you wouldn't want the entire thing populated as soon as you click the popup menu, it would take forever and the user would never see most of it. Can it be done by subclassing NSMenuItem etc? The only alternative I can see would be some sort of custom control based on NSBrowser, but that would be a lot uglier for this sort of selection.
