MonoTouch.Foundation.MonoTouchException An Objective-C exception was thrown. Name: NSInternalInconsistencyException

I seem to be getting this issue when I run an iOS app in Xamarin.

MonoTouch.Foundation.MonoTouchException has been thrown

Objective-C exception thrown. Name: NSInternalInconsistencyException Reason: Could not load NIB in bundle: ’NSBundle ... (loaded)' with name ‘RouteMeViewController'

      

        
        
        
      

    

I am trying to replace GoogleMapsViewController with RouteMeViewController using Objective C library and Binder in the application I was given to work with. My AppDelegate looks like this:

namespace ExampleApp.iOS
{
[Register ("AppDelegate")]
public partial class AppDelegate : UIApplicationDelegate
{

    UIWindow window;
    RouteMeViewController viewController;

    public override bool FinishedLaunching (UIApplication app, NSDictionary options)
    {
        window = new UIWindow (UIScreen.MainScreen.Bounds);

        viewController = new RouteMeViewController ();
        window.RootViewController = viewController;
        window.MakeKeyAndVisible ();

        return true;
    }

}

      

        
        
        
      

    

RouteMeViewController

namespace ExampleApp.iOS
{
public partial class RouteMeViewController : UIViewController
{

    RMMapView MapView { get; set; }

    public RouteMeViewController () : base ("RouteMeViewController", null)
    {
    }

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

        MapView = new RMMapView(View.Frame, new RMOpenStreetMapSource().Handle);
        MapView.AutoresizingMask = UIViewAutoresizing.FlexibleDimensions;

        if (UIScreen.MainScreen.Scale > 1.0)
            MapView.AdjustTilesForRetinaDisplay = true;

        Add (MapView);
    }

}

      

        
        
        
      

    

}

Any help or guidance is greatly appreciated, thanks!
