iOS: Detect when my UIView is add in other view

CustomView *customView = [...];
[self.view addSubview:customView];

I need to detect in my CustomView class when it is added in other views or when my superview changes.

Solution

  • You can use willMoveToSuperview: and didMoveToSuperview to detect when the view is moved around. layoutSubviews will be called when the superview changes frame.
