 A1 delegate == nil? YES
 B1 weakDelegate=MyTasky.NumberTableViewControllerController
 A2 delegate == nil? YES
 B2 weakDelegate=MonoTouch.UIKit.UIScrollView+_UIScrollViewDelegate

UITableViewControllerを継承したクラスの中

public override void ViewDidLoad ()
{
    base.ViewDidLoad ();
    Console.WriteLine ("A1 delegate == nil? {0}", (this.TableView.Delegate == null) ? "YES" : "NO");
    Console.WriteLine ("B1 weakDelegate={0}", this.TableView.WeakDelegate.GetType ());
    this.TableView.DecelerationStarted += (sender, e) => {
        Console.WriteLine ("scrolled.");
    };
    Console.WriteLine ("A2 delegate == nil? {0}", (this.TableView.Delegate == null) ? "YES" : "NO");
    Console.WriteLine ("B2 weakDelegate={0}", this.TableView.WeakDelegate.GetType ());
}
