NSArray becomes NSCFArray when passed

Question

I have a method that receives many different kinds of objects and decides what to do with them:

-(void)performAction:(NSObject *)myAction withItem:(Item *)my         


        

Answer 1

You can try using isKindOfClass: instead of isMemberOfClass:.

The first one will return YES for objects that are either instances of the class you send, or subclasses of it, as it may be the case for NSCFArray.
