iphone - 声音输出含义
<p><p>所以我在按下时在我的 <code>UIButton</code> 中添加了一个声音 (.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:</p>
<pre><code>2012-06-21 10:29:51.784 PhotoSlot The default input device's sample rate was changed.
2012-06-21 10:29:51.786 PhotoSlot Audio device's sample rate changed. You may need to restart the simulator.
2012-06-21 10:29:51.786 PhotoSlot Default audio device changed. Restart the simulator to have it use the newly-selected device.
</code></pre>
<p>这是我的声音代码:</p>
<pre><code>NSString* resourcePath = [ resourcePath];
resourcePath = ;
//Initialize our player pointing to the path to our resource
player = [ initWithContentsOfURL:
error:NULL];
//set our delegate and begin playback
player.delegate = self;
;
</code></pre>
<p>谢谢。</p>

<p><p>啊，发布错误对我有帮助。 <a href="https://stackoverflow.com/questions/7961840/what-does-this-gdb-output-mean" rel="noreferrer noopener nofollow">I found this closely related question</a>它也具有与您所看到的相同的输出。</p>
<p>但我认为您应该采用的真正解决方案(假设您使用 ARC)<a href="https://stackoverflow.com/a/7744831/981049" rel="noreferrer noopener nofollow">is found in this other answer</a> :您需要在播放声音时为您的“<code>AVAudioPlayer</code>”实例保留一个强大的引用。让您的播放器成为“<code>strong</code>”ivar(实例变量)，在播放新声音之前，设置“<code>self.player = nil;</code>”，这应该可以解决您的问题。</p>
<p>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。</p></p>
