How Can I Underline the Button Text of UIButton?

Question

The text is coming form a database. I would like to use it for a button and underline the text of the button. How can I do that?

Answer 1

In Swift 3 the following extension can be used for an underline:

extension UIButton {
    func underlineButton(text: String) {
        let titleString = NSMutableAttributedString(string: text)
        titleString.addAttribute(NSUnderlineStyleAttributeName, value: NSUnderlineStyle.styleSingle.rawValue, range: NSMakeRange(0, text.characters.count))
        self.setAttributedTitle(titleString, for: .normal)
    }
}
