在我的Xamarin.iOS项目中，我试图从UITableViewController推送UIViewController，但这个错误会出现在Main.cs中：

基础.MonoTouchException：Objective-C异常抛出名称：NSUnknownKeyException原因：[ setValue：forUndefinedKey：]：该类与staticDataSource键的键值编码不兼容。

我已经看到了一些关于如何修复XCode或Xamarin Studio中类似错误的建议，但我正在使用Visual Studio 2019（Windows）和iOS设计器，这些建议并不适用。我尝试过清理、重建、重新启动VS、重新连接到Mac服务器、重新启动Mac服务器和重新启动计算机。
下面是我的UIViewController designer.cs文件中的outlet代码：

namespace TestProject.iOS.Controllers.Status_Change
{
    [Register ("ReturnTimeViewController")]
    partial class ReturnTimeViewController
    {
        [Outlet]
        [GeneratedCode ("iOS Designer", "1.0")]
        UIKit.UIDatePicker ReturnDatePicker { get; set; }

        [Outlet]
        [GeneratedCode ("iOS Designer", "1.0")]
        UIKit.UIDatePicker ReturnTimePicker { get; set; }

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

            if (ReturnTimePicker != null) {
                ReturnTimePicker.Dispose ();
                ReturnTimePicker = null;
            }
        }
    }
}

错误消息中的“staticDataSource”键是什么？我在项目的任何地方都找不到对那个键的引用。我如何使类键值编码兼容一个不存在的键？
