AudioFileSetProperty returning 'kAudioFileUnsupportedPropertyError (pty?)'

Question

I\'m having difficulties writing a audio file\'s metadata:

AudioFileID fileID = nil;
AudioFileOpenURL((__bridge CFURLRef) url, kAudioFileReadWritePermission,

Doing almost the same thing here. You can check the OSStatus error with the following code.

NSError *error = [NSError errorWithDomain:NSOSStatusErrorDomain code:status userInfo:nil];
NSLog(@"Error: %@", [error description]);

And what I got is:

Error: Error Domain=NSOSStatusErrorDomain Code=1886681407 "The operation couldn’t be completed. (OSStatus error 1886681407.)"

Could it be that iOS just doesn't allow you to modify kAudioFilePropertyInfoDictionary?

Update:

I just ported idlib3 to iOS and you can use it to modify the ID3 tag. An example project is also included. Check it here https://github.com/rjyo/libid3-ios
