Is -addObserver:forKeyPath:… idempotent? I called it multiple times with the same parameters, but called -removeObserver:forKeyPath: only once, and the object continued to receive KVO notifications.
After adding code to ensure -addObserver:forKeyPath:… was only called once, -removeObserver:forKeyPath: seemed to work as expected. I couldn't find any clear indication in the docs or searching online, although I did find some things that indicate these APIs rather do suck. -- Rick _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
