Underline text in a UITextView

Question

How can I underline text in a UITextView. I understand that I would need to create a subclass of UITextView, but what would go under drawRect

Answer 1

This is how I did it using Swift 5:

let attributedString = NSMutableAttributedString(string: myTextView.text ?? "")
myTextView.linkTextAttributes = [NSAttributedString.Key(rawValue: NSAttributedString.Key.underlineStyle.rawValue): NSUnderlineStyle.single.rawValue] as [NSAttributedString.Key: Any]?
myTextView.attributedText = attributedString
