No, that isn’t an issue. It will be called correctly regardless of where the method was introduced.

Are you sure that the array [self.view subviews] actually contains your views? If it’s empty, nothing will happen. If it contains any views that aren’t of your subclass, you’ll get an exception raised. Try setting a breakpoint at the line you’ve shown, and enter “po [[self view] subviews]”.
