iOS开发：使用AVAudioPlayer，程序在prepareToPlay崩溃

原因是：出现项目中加入了“断点”！  真特么逗～

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.

把下图1所示的断点去掉就OK啦！
