如何使Xamarin.Forms.iOS视图滚动到焦点所在的条目？

using UIKit;
using Xamarin.Forms;
using Xamarin.Forms.Platform.iOS;

[assembly: ExportRenderer(typeof(MyListView), typeof(MyListViewRenderer))]
namespace YourNamespace
{
    public class MyListViewRenderer : ListViewRenderer
    {
        protected override void OnElementChanged(ElementChangedEventArgs<ListView> e)
        {
            base.OnElementChanged(e);

            if (Control != null)
            {
                Control.KeyboardDidShowNotification += KeyboardDidShowNotification;
            }
        }

        private void KeyboardDidShowNotification(object sender, UIKit.UIKeyboardEventArgs e)
        {
            var listView = Element as MyListView;
            var focusedElement = listView.FocusedItem; // 获取获取焦点的条目

            if (focusedElement != null)
            {
                var renderer = Platform.GetRenderer(focusedElement);

                if (renderer.NativeView is UIView nativeView)
                {
                    var scrollView = Control as UIScrollView;

                    // 计算条目位置
                    var itemRect = nativeView.Superview.ConvertRectToView(nativeView.Frame, scrollView);
                    var targetY = itemRect.Y + itemRect.Height;

                    // 滚动到目标位置
                    scrollView.SetContentOffset(new CoreGraphics.CGPoint(0, targetY), true);
                }
            }
        }
    }
}
