uiview - UIView without an UIViewController

Question

How and where to call - setNeedsLayout method of an UIView instance when device rotation changes without necessarily having an UIViewController controlling the view? Basically this could boil down to understanding view life cycle generally without a controller...

Answer 1

I guess some of the things that an UIViewController acts on behalf of the views when the user interacts with them (such as interface orientation changes, etc.) might be be handled by registering to UIApplicationDidChangeStatusBarOrientationNotification in UIView instead.
