这是我的代码:

-(IBAction)playobey:(id)sender { 
    NSString *path = [[NSBundle mainBundle] pathForResource:@"renegadeyamaha" ofType:@"wav"];
    AVAudioPlayer *audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL]; 
    [audioPlayer play];
}

Answer 1

您需要在ivar / property中的某个地方保留对AVAudioPlayer的引用。它可能已经创建，然后在有机会完成播放声音之前立即发布。

我写了一些基于AVAudioPlayer的声音播放器类，它可以使您的生活更轻松:
