我有一个如下的层次结构:

NavigationController
  • Push first ViewController-ViewDidDisappear进入下一个视图时正确触发

  • DialogViewController具有列表的推送-ViewDidDisappear转到下一个时触发

  • 每个列表都会打开一个新的DialogViewController-ViewDidDisappear从不文件

  • 这个上有一些按钮可以打开另一个DialogViewController-VidDidDisappear从不触发

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);
    }
}

那不是如何使用UINavigationControllerand DialogViewController。牢记基本概念UIViewController:一个控制器处理一屏内容(在 iPhone 上)。这意味着,您应该将控制器推入UIViewController's堆栈。这些控制器中的每一个都可以是DialogViewControllers. 这么说你已经可以看到MeasurementViewModel在一个部分中添加视图(根)WorkoutsView是对上述概念的破坏,因此,你违反了 Apple 的设计规则,结果:你的View*()方法不会被调用。

相反:在您的元素上添加一个回调,其中一个可以在导航控制器的堆栈上推送一个新控制器。

您应该能够在 MT.Dialog 的 Github 页面上找到所有必要的文档:https ://github.com/migueldeicaza/MonoTouch.Dialog或 Xamarin 博客:http ://blog.xamarin.com/2012/02/10 /easy-create-ios-user-interfaces-with-monotouch-dialog/
