AVAudioPlayer doesn't play audio

Question

I am trying to play a mp3 file but not playing. There is no error. Just not playing.

I've imported necessary files:

#import <AudioToolbox/AudioServices.h>
#import <AudioToolbox/AudioToolbox.h>
#import <AVFoundation/AVFoundation.h>

And this is my code:

NSError *error;
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSString *soundFilePath = [NSString stringWithFormat:@"%@/music.mp3", documentsDirectory];

    NSURL *soundFileURL = [NSURL fileURLWithPath:soundFilePath];

    AVAudioPlayer *player = [[AVAudioPlayer alloc] initWithContentsOfURL:soundFileURL error:&error];
    player.numberOfLoops = -1; //Infinite
    player.volume=1;
    player.delegate=self;
    [player prepareToPlay];
    [player play];

Nothing is wrong with mp3 file. I can play it on my iPhone's player but not playing on my app.

One of things you have to watch out for with AVAudioPlayer is that if it has to remain allocated while playing. If you make AVAudioPlayer *player an ivar I think your problem will go away.
