如何防止按钮突出显示

Question

I have a project with 2 buttons on my storyboard, I can click both at the same time, but only one triggers.

Is it possible for the second one to not get highlighted unless the first is pressed prior?

Answer 1

Set both buttons' exclusiveTouch property as true.

When exclusiveTouch property is set to true, you won't be able to touch both of them at the same time.

@IBOutlet weak var button1: UIButton!
@IBOutlet weak var button2: UIButton!

override func viewDidLoad() {
    super.viewDidLoad()

    button1.exclusiveTouch = true
    button2.exclusiveTouch = true
}
