Can you elaborate?

I specifically didn't want to use that solution because the class is spread across numerous categories and adding ivars to support stuff in categories is troublesome from a code management point of view. Apart from that, adding an ivar breaks the otherwise extremely neat encapsulation of the task into a single method that has no external references - blocks make that possible, but the need for a delegate somewhat undermines that benefit. Kyle's solution was fine for my case, so it's a solved issue. --Graham _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
