There is no such thing as a static method in Objective-C; there are class methods and instance methods. Class methods are inherited just like instance methods. Thus, when you say [NSMutableArray array], NSMutableArray's implementation of +array will be invoked (if it exists), regardless of whether or not said method is declared in the @interface of NSMutableArray. b.bum _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
