NSInvalidArgumentException not being caught in code

问题

I'm using selectors to dynamically call functions in Objective-C. My problem is that my @try/@catch block is not catching the exception if I pass an non-existent function name.

In the console I get an uncaught NSInvalidArgumentException and further down I get an uncaught NSException.

I have tried catching the the two types of exceptions in a standard @try/@catch block but they aren't registering. Xcode won't let me compile if I try to catch NSInvalidArgumentException as it's not a recognized type.

Any ideas on how to solve this?

@try {
    SEL s = NSSelectorFromString(@"funName");
    [self performSelector:s withObject: nil];
} 
@catch (NSException/NSInvalidArgumentException exception) {
     NSLog(@"ERROR: %@", [exception message/reason];
}
