I *knew* you were going to say exactly that. :) Specifying nil for the 'object:' parameter just means (and I quote from the NSNotificationCenter reference) "the notification center doesn’t use a notification’s sender to decide whether to deliver it to the observer". All notifications still have a sender, available as the 'object' property of the notification object. If the parameter had been named something like 'objectFilter:' instead, you wouldn't have been confused. As it is, reading the documentation would have cleared up the apparent ambiguity, which is why I keep harping on READING THE DOCUMENTATION. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
