So, what is a push notification in details? Some
UIView with information, that’s showing on top of any other view in your app. Even when you pushing new screen, it still stays on top.
What else? This
UIView definitely has
UIPanGestureRecogniser to swipe it away or pull down for extra content and
UITapGestureRecogniser to do some work when user tap it.
Sounds pretty easy. But how to make it pin on top of all other views?
