Caveat: you ought to listen to Quincey's advice, since it will give a
more robust, or at least a cleaner, implementation.
That said, for the specific situation at hand, UIView has a superview
property that returns a reference to, well, the view's superview (if it
exists). If you have the label as a property of view1 ("theLabel"), you
could do something like the following (in viewController2):
UILabel *theLabel = [[[self view] superview] theLabel];
If it's a tagged view, you could do something like:
NSInteger labelTag = (whatever you set, probably in IB);
UILabel *theLabel = [[[self view] superview] viewWithTag:labelTag];
(Since properties are involved, you are of course free to use dot syntax
in many places above if that's your preference.)
