DialogViewController不解雇ViewDidDisappear

Question

我的等级如下所示：

NavigationController

• 在转到下一个视图时，首先推送ViewController - ViewDidDisappear正确触发
• 推具有列表的DialogViewController - ViewDidDisappear在下一个
• 每个列表都会打开一个新的DialogViewController - ViewDidDisappear从不文件。
• 这里有一些按钮可以打开另一个DialogViewController - VidDidDisappear永不触发。

代码：

 public partial class CustomDialogController : DialogViewController {

    public CustomDialogController() : base (UITableViewStyle.Grouped, null, true) {
    }

    public override void ViewDidDisappear (bool animated)
    {
        base.ViewDidDisappear (animated);
        Console.WriteLine("Gone baby 2");
        // Never Fires
    }
  }

public partial class WorkoutsView : DialogViewController
{

    public override void ViewDidDisappear (bool animated)
    {
        base.ViewDidDisappear (animated);
        Console.WriteLine("Gone baby");
        // Here is where you can add your custom code for when the DialogViewController disappears
    }


    public WorkoutsView (MetaFitness.BL.MetaFitnessManager manager) : base (UITableViewStyle.Grouped, null, true)
    {
        this.Title ="Title";
        WorkoutViewModel WorkoutDetail = new WorkoutViewModel();
        //var bc = new BindingContext (this, WorkoutDetail, "Details");
        //detailView = new DialogViewController(bc.Root,true);
        List<Workout> workouts = manager.GetWorkouts ();

        var abc = new CustomDialogController();
        abc.Root = new RootElement("WorkoutsView");
        Root = abc.Root;
        Section section = new Section ("Workouts");
        foreach (var wo in workouts) {
            string name = string.Empty;

            CustomDialogController WorkoutController = new CustomDialogController();
            WorkoutController.Root = new RootElement(wo.Name);
            RootElement wSection = WorkoutController.Root;

            var s2 = new Section();
            var mvm2 = new MeasurementViewModel();
                            // the code for this is similar to CustomDialogController - never fires
            s2.Add(new MeasurementViewController(mvm2).Root);
            wSection.Add (s2);


            section.Add(wSection);  

        }
        Root.Add(section);
    }
}

这不是如何使用UINavigationController和DialogViewController。记住UIViewController的基本概念:一个控制器处理大量内容(在iPhone上)。这意味着，您应该在UIViewController's堆栈上推送控制器。每个控制器都可以是DialogViewControllers。这么说，您已经可以看到，在MeasurementViewModel的一个部分中添加WorkoutsView的视图(根)是对上述概念的突破，因此，您违反了苹果的设计规则，结果是:您的View*()方法不会被调用。

相反:对元素添加一个回调，其中一个元素可以在导航控制器的堆栈上推送一个新的控制器。
