AVAudioPlayer初始化时，在模拟器中报异常

解决方法是去掉全局断点或者设置全局断点类型为Objective-C，如下：

到网上找了些资料：
The problem was I normally develop with a breakpoint set to "All Exceptions", and the actual exception thrown was __cxa_throw. Which apparently turns out to be in C++ libraries that are used to implement AVAudioPlayer. By changing the breakpoint to "All Objective-C Exceptions" the program ran fine. (This can be done by editing the breakpoint and changing the Exception field to Objective-C.

大概意思是说这个异常是来自C++中，用来实现AVAudioPlayer的。。。
