Finding unicode characters in system font in swift for setting attributed titles in buttons

Question

I am doing cs193p and for my homework I need to tweak around with the unicode characters that are only available in system font. How do I find these unicode characters in Xcode to set them as attributed titles on the buttons in my UI.

Answer 1

You can set an unicode char as button title like:

@IBOutlet weak var testButton: UIButton!
// ...

override func viewDidLoad() {
  super.viewDidLoad()
  testButton.setTitle("😄", for: UIControlState.normal)
}

If you have an specific unicode, you can try that:

testButton.setTitle(String("\u{20e0}"), for: UIControlState.normal)

I hope this can help you.
