Xamarin iOS-从自定义UITableViewCell类引用UIView的问题

我想在单元格中点击视图时创建一个简单的动画。点击此视图时，我想将其颜色更改为蓝色，并将其滑动到屏幕右侧

我面临两个挑战：

我如何引用被点击的确切视图 目前，不止一个视图被更改为蓝色，甚至不是被点击的视图，而我只希望点击的视图会更改

视图未滑动/隐藏。这是一个信息覆盖。我想通过将它向右滑动来隐藏它，如果它被拉出（为了隐藏信息），然后将它向后滑动到左侧，当用户再次点击它时显示信息。基本上是打开/关闭动画

任何帮助都将不胜感激

  public override UITableViewCell GetCell (UITableView tableView, NSIndexPath indexPath)
    {
        cell = tableView.DequeueReusableCell (CustomCell.Key) as CustomCell;

        if (cell == null) {

            cell = new CustomCell ();

        }

        try
        {
            cell.cellImageView.Image = TableItems[indexPath.Row];

            tapOnOverlay = new UITapGestureRecognizer(HideTheOverlay);
            cell.overlay.UserInteractionEnabled = true;
            cell.overlay.AddGestureRecognizer(tapOnOverlay);

    }
        catch (Exception imageException)
        {
            Console.Write(imageException.Message);
        }

        return cell;
    }


 public void HideTheOverlay()
    {
        try{

            UIView.Animate(2.0,()=> {

// How do I get a reference to the exact view that was tapped on here??

cell.overlay.Layer.BackgroundColor = UIColor.Blue.CGColor;

// This does not move the view. Nothing happens here

cell.overlay.Layer.Frame = new RectangleF(
                        new PointF((float)cell.overlay.Layer.Frame.Location.X + 200, 
                            (float)cell.overlay.Layer.Frame.Location.Y),
                        (SizeF)cell.overlay.Frame.Size);


            });

        }catch(Exception ex)
        {
            Console.Write(ex.Message + ex.StackTrace);

        }

我找到了解决上述问题的办法

我在

HideOverlay

函数中将

uitappesturerecognizer

作为参数传递，因此为了获得选中/点击的视图，我通过从手势识别器调用

view

属性来访问它。从那里，我可以通过访问视图的

层

来设置视图的动画

下面是我的打开/关闭动画的完整实现

public override UITableViewCell GetCell (UITableView tableView, NSIndexPath indexPath)
    {
        CustomCell cell = tableView.DequeueReusableCell (CustomCell.Key) as CustomeCell;

        if (cell == null) {

            cell = new CustomCell ();

        }
            tapOnOverlay = new UITapGestureRecognizer(HideTheOverlay);
            cell.overlay.AddGestureRecognizer(tapOnOverlay);
            cell.overlay.UserInteractionEnabled = true;

       catch (Exception imageException)
        {
            Console.Write(imageException.Message);
        }

        return cell;
    }

隐藏覆盖功能

     public void HideTheOverlay(UITapGestureRecognizer tap)
    {
        try{

            UIView.Animate(1.5,()=> {

                float offsetXClose = (float)UIScreen.MainScreen.Bounds.Width - ((float)tap.View.Layer.Frame.Location.X + 20);

                float offsetXOpen = (float)UIScreen.MainScreen.Bounds.Width - ((float)tap.View.Layer.Frame.Width);


                float currentXPosition = (float)tap.View.Layer.Frame.Location.X;

                float finalXPosition = currentXPosition + offsetXClose;


                if(currentXPosition == finalXPosition) //Means the overlay is already closed. We should open it
                {

                    //Open the overlay by moving it to the left
                    tap.View.Layer.Frame = new RectangleF(
                        new PointF((float)tap.View.Layer.Frame.Location.X - offsetXOpen, 
                            (float)tap.View.Layer.Frame.Location.Y),
                        (SizeF)tap.View.Frame.Size);

                }else{

                    //Close the overlay, by moving it to the right
                    tap.View.Layer.Frame = new RectangleF(
                        new PointF((float)tap.View.Layer.Frame.Location.X + offsetXClose, 
                            (float)tap.View.Layer.Frame.Location.Y),
                        (SizeF)tap.View.Frame.Size);
                }


            });

        }catch(Exception ex)
        {
            Console.Write(ex.Message + ex.StackTrace);

        }

    }

不确定这是否是问题的根源，但您是否意识到如果重复使用该单元，您将以不止一个手势识别器结束？这是真的。我没有意识到这一点。我所要做的就是给自定义单元格中的视图设置动画。我如何使用最佳实践来实现这一目标？
