How do I catch global exceptions?

Is there a way to catch global "crashing" app exceptions like objc_exception_throw, EXC_ARITHMETIC etc. in code? I need that because I want to do some things bef开发者_如何学Core the app gets killed by the system.

You can set a handler for any uncaught exception by using NSSetUncaughtExceptionHandler.

The relevant docs from Apple are here: http://developer.apple.com/mac/library/documentation/cocoa/conceptual/Exceptions/Concepts/UncaughtExceptions.html#//apple_ref/doc/uid/20000056-BAJDDGGD
