测试游戏的时候，由于听背景音乐实在听地烦了，便将背景音乐的效果给关闭了
没想到接下来就出现了问题！
值得注意的是，这个问题在我关闭背景音效之前一直就没有出现过~
我做的也是一个类似于cut the rope 的切割类物理游戏，因此在每次执行切割操作的时候都会播放一段“唰”的音效
自从关掉了背景音效，播放“唰”切割音效、程序逻辑判断切割的时候就会停顿一下，说的不好听就是卡一下
虽然只是很短暂的卡一下，但这种情况明显会让玩家感到很不爽，因此，我也感到很不爽！
总之，现在的问题就是如何将这个bug给去除掉了。。
控制台上面的所有输出如下：

我将背景音效关闭，发现只有在第一次播放“唰”切割音效的时候才会报出以下错误，此时程序表现出卡一下的效果：
2011-09-27 16:33:44.378 GoldMine0.4[7212:c503] Denshion::CDAudioManager - Audio session set category AVAudioSessionCategorySoloAmbient failed with error Error Domain=NSOSStatusErrorDomain Code=-50 "The operation couldn’t be completed.

大意可能是说没有找到所指定的播放类，但是作为补偿，有其他的方式可以播放出该音效(胡乱猜测，不知正确与否)~
在网上查了一下资料，给出一个有用的连接：http://www.cocos2d-iphone.org/forum/topic/8499
问题和我遇到的问题不一样，但是上面给出连接的那个问题包含了我所遇到的问题
对于该问题，某某大侠的回复如下：
Audio doesn't work correctly in the simulator. I only look at issues that are confirmed on devices, please test on a device.
As for your compiler warning, you need to import SimpleAudioEngine.h or CDAudioManager.h in your HelloWorld header file.
意思差不多就是：模拟器里面对声音效果的表现不正确，但是如果是在真机上的话，则能够正确表现~
至此，问题差不多结束了，不过很遗憾的是，我没有证书，虽然有itouch4代，但是无法进行真机测试，汗~
