Ios 选定行上的Apple Watch表崩溃

我正在使用Xamarin开发一个Apple Watch应用程序。我添加了一个表（WKInterfaceTable）并用代码填充它。但当我点击一行时，应用程序立即崩溃

为了做到这一点，我实际上手动编辑了序列图像板XML文件，因为简单地在序列图像板上拖放一个表是行不通的。以下是XML：

如果崩溃发生在选择项时，而不是在显示表时，那么我假设这与行选择代码有关，并从那里开始

根据您尝试执行的操作，这里有两个选项：

DidSelectRow

选中行并希望操作某些数据或移动到其他视图时使用

public override async void DidSelectRow(WKInterfaceTable table, nint rowIndex)
{
    var contextForNextInterfaceController = rows[(int)rowIndex]; // this depends how you have set up the table.
    Console.WriteLine($"Row selected: {rowData}");
    PushController("TheNextInterFaceController", contextForNextInterfaceController);
}

GetContextForSegue

在iOS Designer或Xcode中设置segue时使用，以便为正在使用的下一个接口控制器设置上下文

public override NSObject GetContextForSegue(string segueIdentifier, WKInterfaceTable table, nint rowIndex)
{
    // Can check segueIdentifier if using more segues
    return new ContextForNextInterfaceController() // This needs to sub class NSObject
    {
        model = modelForNextInterfaceController,
    };
}

设置上下文后移动到另一个视图时，您将使用文本强制转换上下文对象，并检查它是否属于您要查找的类型：

public override void Awake(NSObject context)
{
    base.Awake(context);
    Console.WriteLine("{0} awake with context", this);
    var currentContext = context as ContextForNextInterfaceController;
    if (currentContext != null)
    {
        // Do stuff with context
    }
}

如果您可以发布界面控制器代码或行选择代码，那么我可能可以提供更多帮助。此外，如果您在应用程序输出中遇到任何错误，这也会有所帮助

=========================================================================== 更新

好的，从您的错误输出中，我会说是

FavoriteRowController

缺少插座或故事板中设置了错误的类

此类不符合key InterfaceTable的键值编码。'

当您缺少插座或删除了插座但未删除情节提要中的链接时，这是一个常见错误

RowController不需要是InterfaceController，所以我会这样设置：

FavoriteRowController的代码：

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

    public override void Awake(NSObject context)
    {
        base.Awake(context);

        this.LoadTableData();

        // Configure interface objects here.
        Console.WriteLine("{0} awake with context", this);
    }

    public override void WillActivate()
    {
        // This method is called when the watch view controller is about to be visible to the user.
        Console.WriteLine("{0} will activate", this);
    }

    public override void DidDeactivate()
    {
        // This method is called when the watch view controller is no longer visible to the user.
        Console.WriteLine("{0} did deactivate", this);
    }

    private void LoadTableData()
    {
        var cityNames = new[] { "r1", "r2", "r3", "r4", "r5" };

        InterfaceTable.SetNumberOfRows(cityNames.Length, "default");

        for (var i = 0; i < cityNames.Length; i++)
        {
            var row = (FavoriteRowController)InterfaceTable.GetRowController(i);
            row.RowLabel.SetText(cityNames[i]);
        }
    }
}

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

    public override void Awake(NSObject context)
    {
        base.Awake(context);

        // Configure interface objects here.
        Console.WriteLine("{0} awake with context", this);
    }

    public override void WillActivate()
    {
        // This method is called when the watch view controller is about to be visible to the user.
        Console.WriteLine("{0} will activate", this);
    }

    public override void DidDeactivate()
    {
        // This method is called when the watch view controller is no longer visible to the user.
        Console.WriteLine("{0} did deactivate", this);
    }
}

using Foundation;

namespace WatchConnectivity.OnWatchExtension
{
    public partial class FavoriteRowController : NSObject
    {
        protected FavoriteRowController()
        {
        }
    }
}

FavoriteRowController.designer.cs的代码：

[Register("InterfaceController")]
partial class InterfaceController
{
    [Outlet]
    public WKInterfaceTable InterfaceTable { get; set; }

    void ReleaseDesignerOutlets()
    {
        if (InterfaceTable != null)
        {
            InterfaceTable.Dispose();
            InterfaceTable = null;
        }
    }
}

[Register("FavoriteRowController")]
partial class FavoriteRowController
{
    [Outlet]
    public WKInterfaceLabel RowLabel { get; set; }

    void ReleaseDesignerOutlets()
    {
    }
}

using Foundation;
using System.CodeDom.Compiler;

namespace WatchConnectivity.OnWatchExtension
{
    [Register ("FavoriteRowController")]
    partial class FavoriteRowController
    {
        [Outlet]
        public WatchKit.WKInterfaceLabel RowLabel { get; set; }

        void ReleaseDesignerOutlets ()
        {
            if (RowLabel != null) {
                RowLabel.Dispose ();
                RowLabel = null;
            }
        }
    }
}

检查这个

我修复了它，这是因为我的RowController类应该派生自

NSObject

，而不是

WKInterfaceController

如果它加载了表，那么它可能不是脚本。您是否也可以添加您在选择表行时使用的代码？您使用的是xamarin studio还是VS？另外，我不会手动编辑故事板文件，除非它是一个小更改（一个简单的值）。它不像Android，ID是生成的，很容易搞乱。
