You can find the following macros implemented in
NSException.h. They are obsolete and should not be used. See Exception Programming Topics for information on how to handle exceptions.NS_DURINGNS_ENDHANDLERNS_HANDLERNS_VALUERETURNNS_VOIDRETURNManaging Object Allocation and Deallocation

Whether there’s an uncaught exception handler function, any uncaught exceptions cause the program to terminate, unless the exception is raised during the posting of a notification.
