Using Xcode 4, is it still possible to create a controller class that is derived from NSObject as described in chapter 8? I cant seem to make it go and according to this link, http://developer.apple.com/library/ios/#documentation/IDEs/Conceptual/Xcode4TransitionGuide/InterfaceBuilder/InterfaceBuilder.html one has to derive the controller from NSWindowController to let the interface builder magic happen. Is this correct or can controllers still be derived from NSObject as described in chapter 8?
Thanks for the clarification, Sal
p.s. great book, will there be a version specific to xcode 4?
