How to catch __cxa_throw Programmatically in iOS

Question

Some functions in AudioToolBox always throw __cxa_throw, at the same time the function such as ExtAudioFileDispose works well, the return value zero which is normal. When I want to use try {} catch(...) {} block catch this exception, but this doesn't work. While By All Exceptions Of Xcode, this exception could be caught. Here, just want to know what __cxa_throw is, and how to Programmatically catch it?
