My init starts like this:
- (id) init {
[super init];
sounds = makeDictFromArrayOfURLs(getNoiseFileURLs());
[sounds retain];
NSURL *theFirstNoise = [[sounds allKeys] objectAtIndex:0];
CFURLRef uref = (CFURLRef)theFirstNoise;
OSStatus ret = AudioServicesCreateSystemSoundID(uref, &chosenNoise);
When we get to that last line, it throws this:
2011-06-09 23:19:18.744 SuperTimer[94516:207] -[NSPathStore2 _cfurl]: unrecognized selector sent to instance 0x940cfb0
2011-06-09 23:19:18.746 SuperTimer[94516:207] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[NSPathStore2 _cfurl]: unrecognized selector sent to instance 0x940cfb0'
Yeah, it's a bit uncompact for debugging.
Just before I get the dump, theFirstNoise contains the expected (sort of) data. (It's description method prints a weird form, but I am informed that's normal.)
Off the top of my head, it looks like theFirstNoise
is actually an NSPathStore2
(a private subclass of NSString
) instead of an NSURL
.
Edit: NSPathStore2
objects will contain file paths. If you need to turn these into NSURL
s, you can simply pass them to +[NSURL fileURLWithPath:]
.
This line:
NSURL *theFirstNoise = [[sounds allKeys] objectAtIndex:0];
is the problem: [sounds allKeys] returns an NSArray of keys, and objectAtIndex: therefore is returning an NSString, and not the URL. I wish the compiler would have been a little more helpful.
