mvvmcross splitview doesn't work on ipad

Question

I'm trying to run the NPlus1DaysOfMvvmCross N=24 SplitView tutorial.

It works fine under iphone simulator. The buttons navigate to the red and blue views, however they don't look quite the same as the video (no border).

Under ipad I just get a grey screen after the mvvmcross splash.

The output looks OK and i've verified by debug that it is creating the presenter here:

protected override IMvxTouchViewPresenter CreatePresenter()
{
    if (UIDevice.CurrentDevice.UserInterfaceIdiom == UIUserInterfaceIdiom.Pad)
        return new SplitPresenter(_window);

        return base.CreatePresenter();
}

How can I work out what the issue might be?

Are you running the N=24 project as is or did you make any changes to the github code you pulled down? — PkL728, Jul 08 '14 at 20:33
I started off as is with a clean slate. Now I am modifying to debug. — Michael Ribbons, Jul 08 '14 at 21:16
I think UISplitViewController wants the views to be set in the constructor. That seems to work. It doesn't respond to updating ViewControllers array after it has been shown. — Michael Ribbons, Jul 08 '14 at 21:17
Stuart's original example is shown running under iOS 6 - So I wonder if something has changed between then and iOS 7.1. — Michael Ribbons, Jul 08 '14 at 21:18

I got it working by making a new SplitViewController with each SplitPresenter.Show() request

    public override void Show(Cirrious.MvvmCross.ViewModels.MvxViewModelRequest request)
    {
        var viewController = (UIViewController)Mvx.Resolve<IMvxTouchViewCreator>().CreateView(request);

        if (request.ViewModelType == typeof(FirstViewModel))
            left = viewController;
        else
            right = viewController;


        _window.RootViewController = new SplitViewController ( left, right );
    }

Full example here: https://github.com/mribbons/NPlus1-N-24-SplitView

I'm not sure if this is Bad(tm).

Stuart Lodge I would like to hear your input on this. Also let me know if you want me to create a PR against the tutorials repo. — Michael Ribbons, Jul 08 '14 at 22:36
