Assuming that 'scrambleState' is a method of the 'gameTile' class, then it doesn't matter that it's not a UIView method -- it only matters that it's a method of the objects you send the selector to, i.e. the subviews. One thing to check: if your 'scrambleState' actually has a parameter: - (void) scrambleState: … Then you need '@selector(scrambleState:)', not '@selector(scrambleState)'. It's an easy thing to overlook. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
