设计图如下:

1.代码如下:
//登录方式的选择
let selectedLoginBtn: UIButton = {
let button = UIButton()
button.titleLabel?.font = UIFont.systemFont(ofSize: 12.plan_scaleValue)
let attributedStr: NSMutableAttributedString = NSMutableAttributedString.init(string: "账号密码登录")
let titleRange: NSRange = NSRange.init(location: 0, length: attributedStr.length)
let number: NSNumber = NSNumber(integerLiteral: NSUnderlineStyle.styleThick.rawValue)
attributedStr.addAttributes([NSUnderlineStyleAttributeName: number,
NSForegroundColorAttributeName: COLOR_222222,
NSFontAttributeName: UIFont.systemFont(ofSize: 12.plan_scaleValue)],
range: titleRange)
button.setAttributedTitle(attributedStr, for: UIControlState.normal)
button.addTarget(self, action: #selector(selectedLoginAction(_ :)), for: .touchUpInside)
button.isUserInteractionEnabled = true
button.translatesAutoresizingMaskIntoConstraints = false
return button
}()
2.NSUnderlineStyle中的key值对应的解释说明
case styleNone //无下划线
case styleSingle // 有下划线,样式为单细线
@available(iOS 7.0, *)
case styleThick //有下划线,样式为单粗线
@available(iOS 7.0, *)
case styleDouble //有下划线,样式为双细线
@available(iOS 7.0, *)
public static var patternSolid: NSUnderlineStyle { get } //有下划线,样式为连续实现
@available(iOS 7.0, *)
case patternDot //有下划线,样式为虚线 比如这样：－－－－－－
@available(iOS 7.0, *)
case patternDash //有下划线,样式为破折线 比如这样：—— —— ——
@available(iOS 7.0, *)
case patternDashDot //有下划线,样式为连续的点和破折线 比如这样：——－——－——－
@available(iOS 7.0, *)
case patternDashDotDot //有下划线,样式为连续的破折号、点、点 比如这样：——－——－——－
@available(iOS 7.0, *)
case byWord //在有空格的地方不设置下划线／删除线
}
