How to create a circular button in Swift? [closed]

Question

I want to make a circular thumbs up and thumbs down button.

Should I use a ImageView or a Button as the super class?

How would I do this in Swift?

Answer 1

Here is an example round button:

Swift 3, 4, 5:

override func viewDidLoad() {     super.viewDidLoad()          let button = UIButton(type: .custom)     button.frame = CGRect(x: 160, y: 100, width: 50, height: 50)     button.layer.cornerRadius = 0.5 * button.bounds.size.width     button.clipsToBounds = true     button.setImage(UIImage(named:"thumbsUp.png"), for: .normal)     button.addTarget(self, action: #selector(thumbsUpButtonPressed), for: .touchUpInside)     view.addSubview(button) }  @objc func thumbsUpButtonPressed() {     print("thumbs up button pressed") } 

Swift 2.x:

override func viewDidLoad() {     super.viewDidLoad()          let button = UIButton(type: .Custom)     button.frame = CGRect(x: 160, y: 100, width: 50, height: 50)     button.layer.cornerRadius = 0.5 * button.bounds.size.width     button.clipsToBounds = true     button.setImage(UIImage(named:"thumbsUp.png"), forState: .Normal)     button.addTarget(self, action: #selector(thumbsUpButtonPressed), forControlEvents: .TouchUpInside)     view.addSubview(button) }  func thumbsUpButtonPressed() {     print("thumbs up button pressed") }
