How do you play an mp3 in a Mac Application in Xcode 4.2

I'm trying to play an mp3 in a Mac Application in Xcode 4.2. How would I do this?

Solution

  • You are not giving us much to work with...

    If you just want a simple sound, use NSSound:

    NSString *resourcePath = [[NSBundle mainBundle] pathForResource:@"fn" ofType:@"mp3"];
NSSound *sound = [[NSSound alloc] initWithContentsOfFile:resourcePath byReference:YES];
[sound play];
// wait for the sound to play before you release these...

    With NSSound, the sound plays concurrently with your code. A common mistake is to release the sound or resource while it is still playing. Don't do that.

    You can also use QTMovie in QTKit:

    NSError *err = nil;
QTMovie *sound = [[QTMovie movieWithFile:@"fn.mp3" error:&err] retain];
[sound play];

    For more demanding sounds, use CoreAudio
