Does Mvvmcross has support for IOS BottomSheetController

Question

Mvvmcross has perfect support for BottomSheetDialogFragment, Android. It is possible to specify view model and display bottom sheet by navigating to it.

I didn't find something similar for ios. Does MVVMCross supports BottomSheetController? Links to Github repos or blogs are much appreciated.

Answer 1

I ended up with custom presentation attribute and following code in ios presenter, which works fine with navigation service.

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

        AttributeTypesToActionsDictionary.Register<BottomSheetPresentationAttribute>(
            ShowBottomSheet,
            (viewModel, attribute) =>
            {
                if (_bottomSheetControllers.ContainsKey(viewModel))
                {
                    var bottomSheet = _bottomSheetControllers[viewModel];
                    _bottomSheetControllers.Remove(bottomSheet);

                    bottomSheet.DismissViewController(true, null);
                }
                return Task.FromResult(true);
            });
    }

    private Task<bool> ShowBottomSheet(Type viewType, BottomSheetPresentationAttribute attribute, MvxViewModelRequest request)
    {
        var contentController = BottomSheetsHelper.GetContentController(viewType);
        contentController.OnViewCreate(() => (request as MvxViewModelInstanceRequest).ViewModelInstance);

        var bottomSheet = new BottomSheetController(contentController);
        _bottomSheetControllers.Add(contentController.ViewModel, bottomSheet);

        Window.RootViewController.PresentViewController(bottomSheet, true, null);
        return Task.FromResult(true);
    }

    private readonly Dictionary<object, BottomSheetController> _bottomSheetControllers = new Dictionary<object, BottomSheetController>();
