Answering my own question, my use case is similar to the Sketch
example bundled with XCode.
In Sketch, they use KVC to observe an NSArrayController.
I did the same by calling bind:toObject:withKeyPath:options: in
MyDocument windowControllerDidLoadNib: method and it works.
To sum up, I've seen 3 different ways to write this code:
- use an IBOutlet to reference the NSDocument from a NSView
- use [[[self window] windowController] document] from a NSView
(thanks Chaitanya!)
- forget about the NSDocument and use KVC to directly observe the ovals
Using the KVC seems the most natural way to do that in Cocoa.
