從任何接觸點重新排序UITableViewCell（Xamarin）

Question

我試試這個示例 http://b2cloud.com.au/tutorial/reordering-a-uitableviewcell-from-any-touch-point/ 但是在xamarin上這個不行！ 這是我的代碼

public override void WillDisplay (UITableView tableView, UITableViewCell cell, NSIndexPath indexPath) 
    { 
     if(item.Description.Contains("UITableViewCellReorderControl")) 
     { 

       UIView resizedGripView = new UIView(new CGRect(0,0,item.Frame.X,item.Bounds.Height)); 
       resizedGripView.AddSubview(item); 
       cell.AddSubview(resizedGripView); 

       CGSize sizeDifference = new CGSize(resizedGripView.Frame.Size.Width - item.Frame.Size.Width, 
        resizedGripView.Frame.Size.Height - item.Frame.Size.Height); 

       CGSize transformRatio = new CGSize(resizedGripView.Frame.Size.Width/item.Frame.Size.Width, 
        item.Frame.Size.Height/item.Frame.Size.Height); 

       CGAffineTransform transform = CGAffineTransform.MakeIdentity(); 

       transform = CGAffineTransform.Scale(transform, transformRatio.Width, transformRatio.Height); 
       nfloat two = new nfloat (2.0); 
       nfloat df = -sizeDifference.Width/two; 
       nfloat dff = -sizeDifference.Height/two; 
       transform = CGAffineTransform.Translate(transform, df,dff); 
       resizedGripView.BackgroundColor = UIColor.FromRGBA (17, 176, 13, 50); 
       item.BackgroundColor = UIColor.Red; 
       resizedGripView.Transform = transform; 


    } 

Anybody HALP！

解決：

foreach (var item in cell.Subviews) { 
       Console.WriteLine (item); 
       if (item.Description.Contains ("UITableViewCellReorderControl")) { 

        UIView resizedGripView = new UIView(new CGRect(0,0,item.Frame.GetMaxX(),item.Frame.GetMaxY())); 
        resizedGripView.AddSubview(item); 
        cell.AddSubview(resizedGripView); 

        CGSize sizeDifference = new CGSize(resizedGripView.Frame.Size.Width - item.Frame.Size.Width, 
         resizedGripView.Frame.Size.Height - item.Frame.Size.Height); 

        CGSize transformRatio = new CGSize(resizedGripView.Frame.Size.Width/item.Frame.Size.Width, 
         item.Frame.Size.Height/item.Frame.Size.Height); 

        CGAffineTransform transform = CGAffineTransform.MakeIdentity(); 

        transform = CGAffineTransform.Scale(transform, transformRatio.Width, transformRatio.Height); 
        nfloat two = new nfloat (2.0); 
        nfloat df = -sizeDifference.Width/two; 
        nfloat dff = -sizeDifference.Height/two; 
        transform = CGAffineTransform.Translate(transform, df,dff); 

        resizedGripView.Transform = transform; 
        item.Subviews [0].RemoveFromSuperview(); 

       } 
      } 

我忘記GetMaxX & GetMaxY方法。這是工作！
