[click prepareToPlay];

Answer 1

I do not think your file name is correct. 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 AVAudioPlayer in the same method that you use, you should have an instance variable somewhere else, such as a UIViewController. Therefore, ARC does not automatically release this object, and sound can be played.

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 the answer
