Question

对于MVVMCross ios，如何使用不同的TransitionalStyle（如FlipHorizontal样式）而不是使用“ShowViewModel”的默认滑动效果？

[Register("SearchResults")]
public class SearchResultsView : MvxTableViewController
{
    public override void ViewDidLoad()
    {
        Title = "List";
        base.ViewDidLoad();

        var mapButton = new UIButton(new RectangleF(0, 0, 65, 30));
        mapButton.SetBackgroundImage(UIImage.FromBundle("images/map_btn.png"), UIControlState.Normal);
        mapButton.TouchUpInside += MapButtonClicked();
        var rightButton = new UIBarButtonItem(mapButton);
        NavigationItem.RightBarButtonItem = rightButton;

        var bindings = this.CreateBindingSet<SearchResultsView, SearchResultsViewModel>();
        //bindings.Bind(mapButton).To(x => x.ShowMapCommand); //how to do with binding command?
        bindings.Apply();
    }

    private EventHandler MapButtonClicked()
    {
        return (sender, args) =>
        {

            var mapView = new SearchResultMapView {ModalTransitionStyle = UIModalTransitionStyle.FlipHorizontal};
            var navigationController = new UINavigationController(mapView);
            PresentViewController(navigationController, true, null);
        };
    }
}

ViewModels / Views使用Presenter呈现。

对于导航控制器的模态显示，有些人使用MvxModalNavSupportTouchViewPresenter.cs

您可以通过在设置中覆盖CreatePresenter来使用此演示者：

    protected override IMvxTouchViewPresenter CreatePresenter()
    {
        return new MvxModalNavSupportTouchViewPresenter(ApplicationDelegate, Window);
    }

完成此操作后，您应该可以通过添加IMvxModalTouchView继承并在ModalTransitionStyle = UIModalTransitionStyle.FlipHorizontal;的构造函数中设置SearchResultMapView来实现转换效果。

    public class SearchResultMapView 
         : MvxViewController, IMvxModalTouchView
    {
        public SearchResultMapView()
        {
            ModalTransitionStyle = UIModalTransitionStyle.FlipHorizontal;
        }

        // more code here....
    }

或者，如果您想完全自定义视图/视图控制器的表示，那么实现自定义演示器是相当简单的 - 有关更多信息，请参阅{{3中的自定义演示者的一些文章和教程}}

您需要做的就是在推送的视图控制器的新视图中添加一个关闭按钮，并覆盖它的touchupinside，如下所示：

private void CloseBtnTouchUpInside(object sender, EventArgs eventArgs)
{
            DismissModalViewController(false);
}
