    @IBOutlet weak var yourButtonOutlet: UIButton!
override func viewDidLoad() {
    super.viewDidLoad()
    yourButtonOutlet.addTarget(self, action: #selector(t1),for: .touchUpInside)
    yourButtonOutlet.addTarget(self, action: #selector(t2),for: .touchDown)



    // Do any additional setup after loading the view.
}
func t1() {
    print("touch end")
    yourButtonOutlet.frame = CGRect(x: yourButtonOutlet.frame.origin.x + 50, y: yourButtonOutlet.frame.origin.y, width: yourButtonOutlet.frame.size.width, height: yourButtonOutlet.frame.size.height)

}
func t2() {
    print("touch Start")
    yourButtonOutlet.frame = CGRect(x: yourButtonOutlet.frame.origin.x - 50, y: yourButtonOutlet.frame.origin.y, width: yourButtonOutlet.frame.size.width, height: yourButtonOutlet.frame.size.height)

}

// and for change image on click button

var selected  = true
@IBAction func btnUserAction(_ sender: UIButton) {
    if selected  == true {
        sender.setImage(UIImage.init(named: "tick"), for: .normal)
        selected = false;
    }
    else{
        sender.setImage(UIImage.init(named: "unTick"), for: .normal)
        selected = true;
    }
}
