Underline button text in Swift

Question

I have UIButton. In interface builder I set its title to be \'Attributed\'. How can I make its title to be underlined from code in Swift?

@IBOutlet weak var myBt         


        

Answer 1

For swift 5

var attrs : [NSAttributedString.Key : Any] = [
    NSAttributedString.Key.font : UIFont.systemFont(ofSize: 19.0),
    NSAttributedString.Key.foregroundColor : UIColor.blue,
    NSAttributedString.Key.underlineStyle : NSUnderlineStyle.styleSingle.rawValue
]
