c# - xamarin ios c# 下划线 UIButton 文本

Question

我试图在这个 UIButton ("Privacy Policy") 中给文本加下划线。如何做到这一点？这是我的代码:

var PrivacyPolicy = new UIButton(new CGRect(10, s.MxHt - 40, (s.MxWd - 20) / 3, 30));

PrivacyPolicy.BackgroundColor = UIColor.FromRGB(0, 92, 191);
PrivacyPolicy.Font = UIFont.FromName("Roboto", 14f);
PrivacyPolicy.SetTitle("Privacy Policy", UIControlState.Normal);
PrivacyPolicy.TouchUpInside += HandleBtnOpenPrivacyTouchUpInside;            

if (iPad == false)
{
    PrivacyPolicy.Font = UIFont.SystemFontOfSize(12);
}

View.AddSubview(PrivacyPolicy);

另外，我发现这也很管用。谢谢!

        //Set attribute for underlineing information links
        var underlineAttr = new UIStringAttributes { UnderlineStyle = NSUnderlineStyle.Single, ForegroundColor = UIColor.White };

        //Privacy Button Link
        var PrivacyPolicy = new UIButton(new CGRect(10, s.MxHt - 40, (s.MxWd - 20) / 3, 30));
        PrivacyPolicy.BackgroundColor = UIColor.FromRGB(0, 92, 191);
        PrivacyPolicy.Font = UIFont.FromName("Roboto", 14f);            
        PrivacyPolicy.SetAttributedTitle(new NSAttributedString("Privacy Policy", underlineAttr), UIControlState.Normal);
        PrivacyPolicy.TouchUpInside += HandleBtnOpenPrivacyTouchUpInside;            
        if (iPad == false) { PrivacyPolicy.Font = UIFont.SystemFontOfSize(12); }            
        View.AddSubview(PrivacyPolicy);
