问题 I have a view which contains two views. One of those views contains two buttons and some text labels. The other one, with alpha set to 0.25, has an UIActivityIndicatorView to tell the user that the app is working and he must wait until it finishes.

问题 I have a view with the tap function (user interaction is enabled). If I set it without changing alpha it works well.

Here is my code: import UIKit class ViewController: UIViewController { var myView = UIView() var n = 0 override func viewDidLoad() { super.viewDidLoad() setView() changeAlpha() } func changeAlpha() { UIView.animate(withDuration: 5) { self.myView.alpha = 0.1 } }

We had to follow this approach because push notification involves user interaction which is not
