Ios 如何将MonoTouch.Dialog元素嵌入ViewController？

我正在尝试使用这个：

我可以看到视图元素，当我这样做。。。但是，单击其中一个单选元素不会执行任何操作（例如，显示复选框）。不知道我做错了什么

下面是我在ViewDidLoad（）中使用的代码

我发现对话框控制器扩展到viewcontroller的边缘时出现问题

解决方案是添加一个中间UIView作为容器，以强制DialogController保持在正确的边界内

正确的代码是：

var rootElement = new RootElement("Question Text", new RadioGroup("answer", 0))
{
   new Section()
   {
        new RadioElement("Answer A", "answer"),
        new RadioElement("Answer B", "answer"),
        new RadioElement("Answer C", "answer"),
        new RadioElement("Answer D", "answer")
    }
 };

 _questionDialogViewController = new DialogViewController(rootElement);
 _questionDialogViewController.View.BackgroundColor = UIColor.Clear.FromHexString(AppDelegate.EventModel.MainBackgroundColor);
 _questionDialogViewController.View.Frame = new RectangleF(0, 0, 964, 500);

 var answerContainer = new UIView(new RectangleF(30, 150, 964, 500));
 answerContainer.AddSubview(_questionDialogViewController.View);

 View.AddSubview(answerContainer);

var rootElement = new RootElement("Question Text", new RadioGroup("answer", 0))
{
   new Section()
   {
        new RadioElement("Answer A", "answer"),
        new RadioElement("Answer B", "answer"),
        new RadioElement("Answer C", "answer"),
        new RadioElement("Answer D", "answer")
    }
 };

 _questionDialogViewController = new DialogViewController(rootElement);
 _questionDialogViewController.View.BackgroundColor = UIColor.Clear.FromHexString(AppDelegate.EventModel.MainBackgroundColor);
 _questionDialogViewController.View.Frame = new RectangleF(0, 0, 964, 500);

 var answerContainer = new UIView(new RectangleF(30, 150, 964, 500));
 answerContainer.AddSubview(_questionDialogViewController.View);

 View.AddSubview(answerContainer);
