xamarin.ios - Monotouch - 使 UIView 可滚动

Question

我有一个带有 4 个文本框和顶部的 Logo 的 View - 当用户输入信息时，文本板会覆盖其中的一些控件，我怎样才能使 View 滚动以便这不是问题。

我尝试将 View 添加到 UIScrollView但这似乎没有任何作用？

我在下面包含了我如何处理您的情况的片段。如果我对您的理解正确，您不希望有一个可滚动的 View ，而是希望 View 与在字段之间的切换一起移动，以减轻键盘造成的视觉障碍。

祝你好运!

private void ScrollTheView(bool movedUp, float scrollamount, UIView ViewToMove)
    {
        //To invoke a views built-in animation behaviour,
        //you create an animation block and
        //set the duration of the move...
        //Set the display scroll animation and duration...
        UIView.BeginAnimations(string.Empty, System.IntPtr.Zero);
        UIView.SetAnimationDuration(0.15);

        //Get Display size...
        RectangleF frame = ViewToMove.Frame;

        if (movedUp) {
            //If the view should be moved up,
            //subtract the keyboard height from the display...
            frame.Y -= scrollamount;
        }
        else {
            //If the view shouldn't be moved up, restore it
            //by adding the keyboard height back to the original...
            frame.Y += scrollamount;
        }

        //Assign the new frame to the view...
        ViewToMove.Frame = frame;

        //Tell the view that your all done with setting
        //the animation parameters, and it should
        //start the animation...
        UIView.CommitAnimations();

    }
