Ok, let me rephrase that a bit. :-) I'm still a beginner with Cocoa,
but so far I have always managed to keep my actual Objective-C code
(as opposed to NIB files) completely free from references to NSViews
and NSControllers. My ObjC code exposes stuff using KVC, and the
objects in the NIBs watch this stuff and do their magic. Now I
suddenly need do call methods in an NSController, meaning that I need
to have a reference (probably in the form of an IBOutlet) to this
controller somewhere. This is what put me off a bit.
