[MonoTouch] Help displaying UISplitViewController from UIViewController

[Jeff Stedfast]

Hi Chris,

One possibility would be to wrap your ScreenStart view controller in a
UINavigationController. Then, in your Click() event handler, you could
"push" your DataSplitView.

e.g.:

ScreenStart _srcStart;  // declared at AppDelegate class level

AppDelegate.FinishedLaunching(....)
{
    window = new UIWindow(UIScreen.MainScreen.Bounds);

    _srcStart = new ScreenStart();
    UINavigationController nav = new UINavigationController (_srcStart);

    window.RootViewController = nav;
    window.MakeKeyAndVisible();
}

Then...

DataSplitView dsView; // Declared at StartScreen class level

ScreenStart.btnShowData_Click(....)
{
    if (dsView == null)
        dsView = new DataSplitView();

    NavigationController.PushViewController (dsView, true);
}


You'll notice that I moved your view controller declarations into the class
level. This is because you need to make sure that you have a managed
reference to your view controllers so that if/when the runtime tries to
re-surface your view controllers from native code, it can easily map to the
correct object (which it cannot do if you don't have a managed object).

Hope that helps,

Jeff
