iOS + How to catch unhandled exception

Question

We are writing static library. We have done exception handling for the exposed APIs. But still there are few un-handled Exceptions (or OS Exceptions). Can you please let me know

Answer 1

Well, you could always rely on the Catch'em All Principle

For this kind of problem, I always use following code:

@try {
    // do something
}
@catch (NSException *exception) {
    // error happened! do something about the error state
}
@finally {
    // do something to keep the program still running properly
}
