Change a UIView Frame

Question

I have set a UIView in my storyboard and make it an outlet.

 @property (nonatomic, weak) IBOutlet UIView *testView;

Answer 1

Look at the tiny circle to the left of the property. Is it filled in or hollow? If it's hollow, then it means that you have not connected this particular element of the storyboard to the file's owner.

If the circle is filled in, than the outlet IS connected to something on your storyboard. Just make sure it's connected to the right entity, namely the UIViewController (or subclass thereof) that you are declaring testView within.
