How to change Color of button2 in swift when button1 is clicked?

Question

All I want to do is change the backgroundColor of fiveMinButton and tenMinButton when fiveMinButton is clicked. Why doesn\'t this code work? @IBAction

Answer 1

You are writing the action method inside the viewDidload, Try this:

override func viewDidLoad() {
    super.viewDidLoad()

    fiveMinButton.addTarget(self, action: #selector(action(_:)), for: UIControlEvents.touchUpInside)

}

func action(sender: UIButton){
        if sender == fiveMinButton {
            fiveMinButton.backgroundColor = UIColor.gray
            tenMinButton.backgroundColor = UIColor.lightgray
        }
}
