Why would you do this? It is not more convenient. It is actually a hell of a lot less convenient, because now the compiler will warn you about every non-NSObject method you send to kit, even though you might know that kit responds to it. This includes all system-defined methods on NSObject-the-class that aren't part of NSObject-the-protocol, like -valueForKey:. In fact, I can't think of a situation when it *ever* makes sense to type something as id <NSObject> rather than NSObject. --Kyle Sluder _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
