I am trying to play an audio file but I can get it working. I imported the AVFoundation framework.

Here is the code:

NSString *fileName = [[NSBundle mainBundle] pathForResource:@"Alarm" ofType:@"caf"];
    NSURL *url = [[NSURL alloc] initFileURLWithPath:fileName];
    NSLog(@"Test: %@ ", url);

    AVAudioPlayer *audioFile = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:NULL];
    audioFile.delegate = self;
    audioFile.volume = 1;

    [audioFile play];

I am receiving an error nil string parameter

I copied the file to the supporting files folder so the file is there.

Can you guys help me?

Thanks
