                      string.addAttributes([.underlineStyle : NSUnderlineStyle.single.union(.patternDot).rawValue],
                                    range: NSRange(location: 0, length: string.length))

可以使用NSAttributedString在swift中设置下划线 5.

let string = NSAttributedString(string: "Receiver", attributes: [.underlineStyle: NSUnderlineStyle.single.union(.patternDash).rawValue])
label.attributedText = string
