iOS: Detect when my UIView is add in other view
Вопрос
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.
Решение
You can use willMoveToSuperview:
and didMoveToSuperview
to detect when the view is moved around. layoutSubviews
will be called when the superview changes frame.
Другие советы
- For a UIView use
- (void)didMoveToSuperview
- For a UIViewController use
-(void)viewWillAppear:(BOOL)animated
also assign THE TAG of Customview before addsubview and the detect by Particular TAG.
