UIButton does not change its alpha while being pushed

Question

I am programming a game with a end screen. It's a view with a UIImageView on it.

The imageView has a UIVisualEffectView additionaly.

There is a button on my end screen (No, it's not part of the imageView).

If you touch it, it won't change it's alpha, like usual.

Is the button's type set to "Custom" by any chance? Only a "System" button changes visually when pressed (by default). — nebs, Apr 12 '16 at 18:31
Have you tried setting the `adjustsImageWhenHighlighted` and `showsTouchWhenHighlighted` properties on the button? — George Green, Apr 12 '16 at 20:02

All you have to do is to initialize your button with UIButton(type:) and .System as type. Something like this:

var button = UIButton(type: .System)

If you don't use this, your button will not change it's alpha while being pushed.
