Answer 1

Your code should look like below

let image = UIImage(named: "name") as UIImage?
let button   = UIButton(type: UIButtonType.Custom) as UIButton
button.frame = CGRectMake(100, 100, 100, 100)
button.setImage(image, forState: .Normal)
button.addTarget(self, action: "btnTouched:", forControlEvents:.TouchUpInside)
self.view.addSubview(button)
