let image = UIImage(named: "name") as UIImage?
let button = UIButton(type: UIButtonType.custom) as UIButton
button.frame = CGRect(x: 100, y: 100, width: 100, height: 100)
button.setImage(image, for: .normal)
button.addTarget(self, action: Selector("btnTouched:"), for:.touchUpInside)
        self.view.addSubview(button)
