Sure you can. Use LSCopyItemAttributes() with kLSItemContentType.
I've written a category on NSFileManager that, among other things,
will do this. Here's the relevant portion for you:
__
#import Foundation/Foundation.h
@interface NSFileManager (DSFileAdditions)
+ (NSString *)UTIForFile:(NSString *)path;
+ (NSString *)UTIForURL:(NSURL *)url;
@end
@implementation NSFileManager (DSFileAdditions)
+ (NSString *)UTIForFile:(NSString *)path
{
return [self UTIForURL:[NSURL fileURLWithPath:path]];
}
+ (NSString *)UTIForURL:(NSURL *)url
{
NSString *retval = nil;
FSRefPtr fileRef = NULL;
fileRef = calloc( 1, sizeof( FSRef ) );
if ( (fileRef != NULL) (url != nil) [url isFileURL]
(CFURLGetFSRef( (CFURLRef)url, fileRef ) == true) ) {
CFStringRef theUTI = NULL;
if ( LSCopyItemAttribute( fileRef, kLSRolesAll, kLSItemContentType,
(CFTypeRef *)theUTI ) == noErr ) {
retval = [[(NSString *)theUTI copy] autorelease];
CFRelease( theUTI );
}
}
if ( fileRef != NULL )
free( fileRef );
return retval;
}

I *think* this code should work fine under GC (for anyone using it),
but you should probably test it first as I haven't.

Re: NSCollectionView problems
Hello again, On May 23, 2008, at 1:20 PM, Markus Spoettl wrote: I have an NSCollectionView set up with bindings to visualize an NSMutableArray. When I call arrayController:setContent: the view (which initially doesn't have a content assigned) displays the items. So far so good. The problems are these: If there are two many items for one page to display, the vertical scroller appears. However, it's not the correct size. It's displayed as if all items would fit into the view (all but an imaginary 10 pixel row). It doesn't get the correct size until after the view is resized. Is there some way to force the view to recalculate it's scroll bar sizes? Or could this be caused by how the content is assigned (I'm using an array controller)? The second problem is when the view is resized (due to window resizing or any other reason). When the collection view is scrolled down with some item in the middle of the collection selected (so the scrollbar is not on it's topmost position), the resize causes the collection display to jump to the first item row. This problem can be observed in the Apple supplied IconCollection demo. Is there a way to prevent that? For those interested, both issues go away if Automatically Hide Scrollers is switched OFF for the enclosing scroll view. I had scrollers switched off by default for esthetic reasons. Apparently NSCollectionView can't handle that case properly. Does anyone know is this a known issue? If not I'd be glad to file a report.

Cleaning up a singleton
Hi, I have a bit of an odd problem, which may be the result of a bad design decision. My program wraps around a C library, which internally uses a global variable (structure) to manage things, and has functions to access the data. The library requires me to call a function which allocates memory to that global variable, and afterwards call a function which deallocates that memory. My singleton class calls the function to initialise in the init method, but I don't know how to deallocate the memory. Since singleton objects exist until the end of program execution, I assume dealloc wouldn't work with garbage collection. Calling dealloc on a singleton object doesn't even make sense.

Re: Removing the Filename flag in Doc. based Application
On May 23, 2008, at 2:51 PM, [EMAIL PROTECTED] wrote:
How do I set my document based application to omit the filename
reference at
the top of each opened document window?
Kyle Sluder's explanation is quite informative, but it may also be
more complicated than you need. If you really just want to change the
name of your document, you can override -[NSDocument displayName]
like this:
// Adding this method to your document subclass will cause the
// title of every document window to be Foo.
- (NSString *)displayName
{
return @Foo;
}
If you want to also remove the file proxy icon (small icon next to
the window title), you'll likely want to create a custom window
controller as described by Kyle and implement either the -
windowDidLoad: or -awakeFromNib methods such that you get a reference
to the icon button and send it a -setHidden: message, like this:
// Put the following in your custom window controller where it'll
// be executed soon after the window is loaded.
NSButton *fileButton =
[window standardWindowButton:NSWindowDocumentIconButton];
if (fileButton != nil) {
[fileButton setHidden:YES];
}
The reason for putting the code above in a custom window controller
is that ideally, your document class shouldn't be in the business of
defining what the window should look like. The window controller is a
better place for that.

Core Data dynamic attributes and fetching
Hi all,
I have a core data object graph using an SQLite store where several
entities have an attribute containing a date (eg, birthDate). This is
stored as a date type.
I am currently implementing an NSPredicateEditor for building smart
groups. Each smart group simply saves this predicate to an attribute
and then fetches using that.
The problem is that I want to offer to filter by ('days since birth'
== 7), as well as (birthDate == 01/01/01). This is where I have hit a
wall. I can't set a dynamic transient property for daysSinceBirth as
these can't be used in fetch requests, and I can't convert the number
of days to an absolute date as this loses the dynamic-calculation part
of the number. I did think of using a transformable attribute to
convert a second date field to an int, but then apparently this can't
be used in a fetch request either.
I suppose that I could use a placeholder segment of predicate which is
replaced when used, but this seems a bit awkward and inelegant.
Does anyone have any suggestions on how I could achieve this?
Regards,
Ben

Re: NSTextView without word wrap?
You're welcome, but I'd replace this:

[[textView textContainer]
setContainerSize:NSMakeSize(LargeNumberForText, LargeNumberForText)];
with
[[textView textContainer] setContainerSize:NSMakeSize(FLT_MAX,
FLT_MAX)];
hey presto 1 less line of code! FLT_MAX is the largest representable
floating point number. It *may* insulate you from processor
differences, but someone would have to confirm to me that this could
ever be a problem.

NSWindow CoreAnimation Delegate not being called
Hi all, I've been playing with CA and I tried to set up one my objects as the delegate for the frame change animation for an NSWindow by using the following code: CABasicAnimation* anim = [window animationForKey:@frame]; anim.delegate = self; [[window animator] setFrame:NSMakeRect(400, 500, 500, 500) display:YES]; Using this, the window correctly animates but the delegate methods (namely animationDidStop:finished: and animationDidStart:) for the CAAnimation do not get called. When I use the exact same piece of code for setting the delegate of view animations, the delegates do get called.

AEDisposeDesc(evt);
}
return err;
}
int main (int argc, const char * argv[]) {
return QuitApplication(com.apple.itunes);
}
For anything more complex, use a high-level bridge (e.g. see my sig).

Re: How to tell if iTunes is running.
My version wasn't about using the path for something else; it was
only about providing a method that doesn't care what the iTunes
application is called. For example, if someone were to rename it
iTunes 7.6.2, then your version would stop working.
However, as Thomas Engelmeier pointed out in a separate message,
Apple doesn't currently localize the names of its iApps so you're
probably safe.

NSTextField in NSCollectionView aborts editing without notice, solved
I have an NSTextField in an NSCollectionView. If I type in a change to the NSTextField, then without hitting tab or clicking elsewhere in the NSCollectionView I click on a popup menu in the window, the NSTextField aborts the edit and loses the information without any kind of notice being given to the NSTextField. I solved the problem by subclassing NSTextFieldCell and overriding the method endEditing, passing it up to the superclass after first sending an emergency message to the window controller, along with a copy of the NSTextField, indicating it needs to grab the edited string out of the NSTextField because the information is about to be lost. I tried monitoring resignsFirstResponder. I can then click on the NSTextFields in the NSCollectionView and get resignsFirstResponder messages as expected. If I click on an NSTextField and then hit a key to begin an edit, the sequence of messages is as follows: NSTextField gets the message: textShouldBeginEditing The NSTextField delegate, which is an NSCollectionViewItem, gets the message: control:textShouldBeginEditing NSTextField gets the message: textDidBeginEditing The NSTextField delegate gets the message: control:textDidBeginEditing After I type in some text, if I were to click on the popup as described, neither NSTextField nor its delegate gets any of the text did/should end editing messages which correspond with the above messages. FWIW, if rather than clicking on the popup menu I click on another text field, the NSTextField gets both of the textShouldEndEditing messages, but not any textDidEndEditing messages. After those messages, it gets the expected resignsFirstResponder message. If after I click on the popup menu I click on another NSTextField, I do get a resignsFirstResponder message from an NSTextField, but by that time the information in the field I had edited has already been lost. So is this a bug? Is it a feature? Am I missing something? Has someone already found an easier way of dealing with this? If someone else is already wondering about this problem, then this is the way I solved it.

Re: NSWindow CoreAnimation Delegate not being called
I'm no core animation expert, but. This... // self is an NSWindow instance CAAnimation *anim = [CABasicAnimation animation]; [anim setDelegate:self]; [self setAnimations:[NSDictionary dictionaryWithObject:anim forKey:@frame]]; [[self animator] setFrame:NSMakeRect(0,0,0,0) display:YES]; ... works perfectly in my app, calling the delegate methods and all. All other things being equal, the only difference I see is that you use [window animationForKey:@frame] whereas I create a new animation and then add it to the window with [window setAnimations:...]. My *guess* would be that maybe windows don't instantiate default animations until they're needed, whereas frames instantiate them at init. So when you call [window animationForKey:@frame] you're getting nil back. But that's just a guess. I really don't know enough about it. Bug? Feature? I don't know. But this could be a workaround, anyway. -Pete On May 24, 2008, at 7:11 AM, Milen Dzhumerov wrote: Hi all, I've been playing with CA and I tried to set up one my objects as the delegate for the frame change animation for an NSWindow by using the following code: CABasicAnimation* anim = [window animationForKey:@frame]; anim.delegate = self; [[window animator] setFrame:NSMakeRect(400, 500, 500, 500) display:YES]; Using this, the window correctly animates but the delegate methods (namely animationDidStop:finished: and animationDidStart:) for the CAAnimation do not get called.
