That makes no sense at all. +initialize a class method, not an instance method, and it's guaranteed to be called before any other method. > initialize, it's nil.

The above comparison simply checks "self" against a specific Class object, so that this +initialize won't have any effect in subclasses. Once again - you seriously need to take a step back and review the fundamentals docs. It's a dead-end to try to learn by skipping the fundamentals, going straight to the references and thinking in terms of equivalent constructs in Java, C++, or whatever. You need to approach and learn Cocoa on its own terms. sherm-- -- Cocoa programming in Perl: http://camelbones.sourceforge.net _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
