c# - 使用 uitableview 加载 UIView

Question

你好我想在你点击一行uitableview时加载一个UIView。我这样做是因为它是这个链接: ViewController Segue Xamarin但是在打印时给出了以下错误，Man.storyboard 和模拟器也有。下面是带有 uitableview 的 View 代码以及 UITableViewSource 的代码。如果有人可以提供帮助，我将不胜感激。

partial class ListaWodsFemininosViewController : BaseController2
{
    public ListaWodsFemininosViewController (IntPtr handle) : base (handle)
    {
    }

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

        DetalheWodViewController detalhe = (DetalheWodViewController)Storyboard.InstantiateViewController("detalhe");

        List<WodReferencia> Wods = new List<WodReferencia> ();

        WodReferencia ref0 = new WodReferencia {
            Nome        = "Amanda",
            Feminino    = "Three rounds, 9-7- and 5 reps, of:\n" +
                "Muscle-up 135 pound Squat snatch.",
            Masculino   = "Three rounds, 9-7- and 5 reps, of: " +
                "Muscle-up 135 pound Squat snatch."

        };
        Wods.Add (ref0);

        WodReferencia ref1 = new WodReferencia {
            Nome        = "Angie",
            Feminino    = "100 Pull-ups 100 Push-ups 100 Sit-ups 100 Squats.",
            Masculino   = "100 Pull-ups 100 Push-ups 100 Sit-ups 100 Squats."
        };
        Wods.Add (ref1);

        WodReferencia ref2 = new WodReferencia {
            Nome        = "Annie",
            Feminino    = "Double-unders Sit-ups 50-40-30-20 and 10 rep rounds.",
            Masculino   = "Double-unders Sit-ups 50-40-30-20 and 10 rep rounds."
        };
        Wods.Add (ref2);

        WodReferencia ref3 = new WodReferencia {
            Nome        = "Barbara",
            Feminino    = "20 Pull-ups 30 Push-ups 40 Sit-ups 50 Squats Rest precisely 3 minutes between each round. 5 rounds, time each round.",
            Masculino   = "20 Pull-ups 30 Push-ups 40 Sit-ups 50 Squats Rest precisely 3 minutes between each round. 5 rounds, time each round."
        };
        Wods.Add (ref3);

        WodReferencia ref4 = new WodReferencia {
            Nome        = "Chelsea",
            Feminino    = "5 Pull-ups 10 Push-ups 15 Squats Each minute on the minute for 30 minutes.",
            Masculino   = "5 Pull-ups 10 Push-ups 15 Squats Each minute on the minute for 30 minutes."
        };
        Wods.Add (ref4);

        WodReferencia ref5 = new WodReferencia {
            Nome        = "Christine",
            Feminino    = "3 rounds for time of: 500 m Row 12 BW Deadlift 21 Box Jumps.",
            Masculino   = "3 rounds for time of: 500 m Row 12 BW Deadlift 21 Box Jumps."
        };
        Wods.Add (ref5);

        WodReferencia ref6 = new WodReferencia {
            Nome        = "Cindy",
            Feminino    = "5 Pull-ups 10 Push-ups 15 Squats As many rounds as possible in 20 minutes.",
            Masculino   = "5 Pull-ups 10 Push-ups 15 Squats As many rounds as possible in 20 minutes."
        };
        Wods.Add (ref6);

        ...

        gridWods.Source = new FonteTabelaWodsFeminino (Wods,detalhe);
    }

    public override void PrepareForSegue (UIStoryboardSegue segue, NSObject sender)
    {
        if (segue.Identifier == "detalhe") {
            var detalhe = segue.DestinationViewController as DetalheWodViewController;
        }
    }
}

public class FonteTabelaWodsFeminino : UITableViewSource
{

    private List<WodReferencia> wodsFemininos; 
    DetalheWodViewController detLocal;
    private string cellIdentifier = "TableCell";

    public FonteTabelaWodsFeminino (List<WodReferencia> wodsF, DetalheWodViewController det)
    {
        wodsFemininos = wodsF;
        this.detLocal  = det;
    }

    public override nint RowsInSection (UITableView tableview, nint section)
    {
        if (wodsFemininos != null) {
            return wodsFemininos.Count;
        } else {
            return 0;
        }
    }

    public override UITableViewCell GetCell (UITableView tableView, Foundation.NSIndexPath indexPath)
    {
        UITableViewCell cell            = tableView.DequeueReusableCell (cellIdentifier); 
        if (cell == null)
            cell = new UITableViewCell (UITableViewCellStyle.Subtitle, cellIdentifier);

        cell.TextLabel.Lines            = 0;
        cell.TextLabel.SizeToFit ();
        cell.TextLabel.LineBreakMode    = UILineBreakMode.WordWrap;
        cell.DetailTextLabel.Text       = wodsFemininos [indexPath.Row].Masculino;
        cell.TextLabel.Text             = wodsFemininos [indexPath.Row].Nome;
        return cell;
    }

    public override void RowSelected (UITableView tableView, NSIndexPath indexPath)
    {
        detLocal.PerformSegue("detalhe", detLocal);
    }
}

认为您需要为您的 segue 提供一个 Id，如下所示:

刚刚注意到您使用了 Xamarin iOS 设计器，因此这里也有屏幕截图；)
