I have imported audio toolbox and avfoundation to my class and added the frameworks to my project and am using this code to play a sound:

- (void)playSound:(NSString *)name withExtension:(NSString *)extension
{
    NSURL* soundUrl = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:name ofType:extension]]; 
    AVAudioPlayer *audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:soundUrl error:nil];

推荐答案

更新的答案：

我有这个问题。这是一个与ARC和有无关
  prepareForPlay。简单地作出强烈参考它和它的工作。

I've got the issue. It's with ARC and has nothing to do with prepareForPlay. Simply make a strong reference to it and it will work.

@property (nonatomic, strong) AVAudioPlayer *player;

@implementation
@synthesize _player = player;
