I'm fairly familiar with NSNotificationCenter, but I haven't been keeping up-to-date with newer alternatives in the Cocoa framework. At least, it's my understanding that Apple is also pushing key-value observing. Do you know if NSNotificationCenter is something that Apple eventually wants to replace with something like KVO? I like NSNotificationCenter for its simplicity (so-much-so that I haven't been bothered to learn the alternatives).
