我这样做:https://developer.xamarin.com/guides/ios/user_interface/controls/tables/creating-tables-in-a-storyboard/ 但我无法获得public override void PrepareForSegue(UIStoryboardSegue segue, Foundation.NSObject sender) 当我点击桌子时被叫到。

为什么?

以前有人有这个问题吗? 我下载他们的项目并且它可以工作,但它不在我的项目中。为什么?我错过了一些东西,但我不确定它是什么。

public partial class ViewController : UITableViewController
{
    protected ViewController(IntPtr handle) : base(handle)
    {
        // Note: this .ctor should not contain any initialization logic.
    }

    public override void ViewDidLoad()
    {
        base.ViewDidLoad();
        CreateTableItems();
       // Add(table);
        // Perform any additional setup after loading the view, typically from a nib.
    }
    public override void PrepareForSegue(UIStoryboardSegue segue, Foundation.NSObject sender)
    {
        if (segue.Identifier == "TaskSegue")
        { // set in Storyboard
            var navctlr = segue.DestinationViewController as wrestingControllor;
            if (navctlr != null)
            {
                var source = table.Source as ScheduleTableViewSource;
                var rowPath = table.IndexPathForSelectedRow;
                var item = source.GetItem(rowPath.Row);
                navctlr.SetTask(this, item); // to be defined on the TaskDetailViewController
            }
        }
       // var page2ViewController = segue.DestinationViewController as Page2ViewController;

      //  page2ViewController.Name = "dan";
    }


    void errorMessage(string message)
    {
        UIAlertView alert = new UIAlertView()
        {
            Title = "Error",
            Message = message,


        };
        alert.AddButton("OK");
        alert.Show();
    }

    protected void CreateTableItems()
    {
        bool check = NetworkInterface.GetIsNetworkAvailable();
        try
        {
            if (check)
            {

                Service1 client = new Service1();
                var schools = client.School_lists();
                table.Source = new ScheduleTableViewSource(schools, this);

            }
            else
            {
                errorMessage("Error no Internet connection");
                return;
            }
        }
        catch(Exception e)
        {
            errorMessage("Error no Internet connection");
            return;
        }
    }


    public override void DidReceiveMemoryWarning()
    {
        base.DidReceiveMemoryWarning();
        // Release any cached data, images, etc that aren't in use.
    }
