所以我UIButton在按下时添加了一个声音（.wav），但它在调试器中输出了这个，任何人都可以解释或帮助我这是什么：

2012-06-21 10:29:51.784 PhotoSlot[817:1dc0b] The default input device's sample rate was changed.
2012-06-21 10:29:51.786 PhotoSlot[817:21a2b] Audio device's sample rate changed. You may need to restart the simulator.
2012-06-21 10:29:51.786 PhotoSlot[817:1dd0f] Default audio device changed. Restart the simulator to have it use the newly-selected device.

这是我的声音代码：

NSString* resourcePath = [[NSBundle mainBundle] resourcePath];
resourcePath = [resourcePath stringByAppendingString:@"/push.wav"];
    //Initialize our player pointing to the path to our resource
player = [[AVAudioPlayer alloc] initWithContentsOfURL:
          [NSURL fileURLWithPath:resourcePath] error:NULL];
//set our delegate and begin playback
player.delegate = self;
[player play];

谢谢你。

啊，发布错误可以帮助我。 我发现这个密切相关的问题也与您所看到的具有相同的输出。

但是我认为您应该做的真正解决方案（假设您使用的是 ARC）可以在另一个答案中找到：您需要在AVAudioPlayer播放声音时为您的 " " 实例保留一个强有力的参考。使您的播放器成为“ strong” ivar（实例变量），在播放新声音之前，设置“ self.player = nil;”，这应该可以解决您的问题。

另外，关闭模拟器调试器中的所有断点，看看你是否有更好的运气。
