UITapGestureRecognizer – you can recognize the touch not only on the buttons, but on any object on the view, even touching the area itself.
For example: when you click on any place of view, the background color should change from white to red. Create a UIView – the size in the full screen of the device, the background color is white. And we create UITapGestureRecognizer to which we assign the function myviewTapped (see the picture).
