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

Thanks for posting your code, it wasn't clear that you knew how to create an attributed string at all.

This should work:

var attrs = [
    NSFontAttributeName : UIFont.systemFontOfSize(19.0),
    NSForegroundColorAttributeName : UIColor.redColor(),
    NSUnderlineStyleAttributeName : NSUnderlineStyle.StyleSingle.rawValue
]

Swift 4 version:

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