That’s more like the way NSNotificationCenter works — you specify the target and selector, which together act similarly to a function pointer. I’m not sure why, but KVO uses a single method to deliver all notifications. That’s just the way Apple designed it, and KVO is newer than NSNotificationCenter so they must have had a good reason for doing so. That means the only thing that can uniquely distinguish different KVO registrations is the ‘context’ value. —Jens _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
