Can a UIView know when it is on screen
I have a UIView with a lot of components enclosed in it and would like to
update some of them if the view is removed or if its parent view
controller is popped/pushed. Is it possible for a UIView to get this
information
Similar to the method in UIViewController
-(void)viewWillAppear;
Would like something like
-(void)UIViewWillAppear;
