Answer 1

I don't think your file name is right. Try this syntax:

    NSURL *clickURL = [NSURL fileURLWithPath:[NSString stringWithFormat:@"%@/alarm_1.mp3", [[NSBundle mainBundle] resourcePath]]];  
    AVAudioPlayer *audioPlayer = [[AVAudioPlayer alloc]initWithContentsOfURL:clickURL error:nil];

Answer 2

I had a similar problem due to ARC. Instead of defining the AVAudioPlayer in the same method you are using it, you should should have an instance variable somewhere else, such as the UIViewController. This way ARC doesn't auto release this object and audio can play.

Answer 3

NSURL *url = [NSURL fileURLWithPath:[NSString stringWithFormat:@"%@/alarm_1.mp3", [[NSBundle mainBundle] resourcePath]]];

NSError *error;
AVAudioPlayer *audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error];
audioPlayer.numberOfLoops = -1;

[audioPlayer play]; 

This is answer
