Monitor and debug exceptional conditions in code.
SDK
This collection of documents provides the API reference for the Exception Handling framework. This framework provides facilities for monitoring and debugging exceptional conditions in Objective-C code.
Currently only one class reference is part of this collection: the reference for the NSException class, which is defined in NSException.
class NSExceptionThe NSException class provides facilities for monitoring and debugging exceptional conditions in Objective-C programs. It works by installing a special uncaught exception handler via the NSSet function. Consequently, to use the services of NSException, you must not install your own custom uncaught exception handler.
The NSException informal protocol describes methods that NSException objects call on their delegates when exceptions occur. An NSException object does not need to have a delegate. When one does, these delegate methods are asked to approve exception handling and logging for each monitored NSException object.
