聲音輸出含義

Question

所以我在UIButton增加了聲音（.WAV）按下時，但這個輸出在調試器，任何人都可以解釋或幫助我在這是什麼：

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. 

這裏是我的代碼爲：

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]; 

謝謝。

啊，發佈錯誤幫助我。 I found this closely related question，它也具有與您所看到的相同的輸出。

但我認爲你應該做的真正的解決方案（假設你使用ARC），is found in this other answer：你需要保持你的「AVAudioPlayer」實例很強的參考，而周圍的聲音播放。使您的播放器成爲「strong」ivar（實例變量），並在播放新聲音之前，設置「self.player = nil;」，並且應該解決您的問題。

另外，關閉模擬器調試器中的所有斷點，看看你是否有更好的運氣。
