Question

所以我在按下UIButton时添加了一个声音（.wav），但它在调试器中输出了这个，有人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.

以下是我的声音代码：

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];

啊，发布错误可以帮助我。 I found this closely related question也与您所看到的输出具有相同的输出。

但我认为你应该做的真正的解决方案（假设你正在使用ARC），is found in this other answer：你需要为你的“AVAudioPlayer”实例保留一个强大的参考，而声音是播放。让你的播放器成为“strong”ivar（实例变量），在播放新声音之前，设置“self.player = nil;”，这应该可以解决你的问题。

此外，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。
