arrays

Hi!

I'd like to know if there's a way to verify if an index exists before getting it.

So it'd be way to protect my code against:

*** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[NSCFArray objectAtIndex:]: index (2) beyond bounds (0)'

Like in PHP you can do: isset($object[10]); and it'll return true if it exists.

Is there such a method in Objective-C/Cocoa?

Thanks!
