如何在Xamarin C#iOS版中使用UIPageControl

我过去曾研究过钛合金，在那里使用分页控制非常简单。刚开始Xamarin iOS的开发，就被这个页面控制卡住了。不知道如何使用它。我在这里找到了一个例子。它运行良好我的问题是，UIPageControl无用吗？我在这里读到是这样的。Xamarin有任何可以像Titanium的滚动视图一样工作的控件吗请提出比下面代码更好的方法。

这是代码

 public override void ViewDidLoad ()
    {
        base.ViewDidLoad ();

        // Perform any additional setup after loading the view, typically from a nib.
        createAndAddViewsToPagerControl ();
    }
    void createAndAddViewsToPagerControl ()
    {
        try {
            int pageCount = PagerControlMain.Pages;
            Console.WriteLine ("Pages Count in Page Control" + pageCount);

            List<UIColor> _colList = new List<UIColor> {
                UIColor.Red,
                UIColor.Green,
                UIColor.Blue,
                UIColor.Yellow
            };
            int i = 0;
            for (i = 0; i < pageCount; i++) {
                UILabel label = new UILabel ();
                RectangleF rectangle = new RectangleF ();
                rectangle.X = (this.PagerScrollView.Frame.Width * i) + 50;
                rectangle.Y = 0;
                rectangle.Size = this.PagerScrollView.Frame.Size;
                label.Frame = rectangle;
                label.Text = i.ToString ();
                label.TextColor = _colList [i];
                this.PagerScrollView.AddSubview (label);
            }
            this.PagerControlMain.Pages = pageCount;
            PagerScrollView.BackgroundColor = UIColor.Gray;
            PagerScrollView.ContentSize = new SizeF (PagerScrollView.Frame.Width * i, PagerScrollView.Frame.Height);
            this.PagerScrollView.Scrolled += ScrolledEvent;

        } catch (Exception ex) {
            Console.WriteLine ("Exception in PagerControl : " + ex);
        }
    }
    private void ScrolledEvent (object sender, EventArgs e)
    {
        this.PagerControlMain.CurrentPage = 
            (int)System.Math.Floor (this.PagerScrollView.ContentOffset.X
        / this.PagerScrollView.Frame.Size.Width);
        Console.WriteLine ("Scroll Event Fired");
    }
    partial void PagerControlMain_ValueChanged (UIPageControl sender)
    {
        Console.WriteLine ("Current Page " + sender.CurrentPage);
        //throw new NotImplementedException ();
    }
