MvvmCross: Programmatically adding a view to CollectionView's subview - iphone

Question

Depending on user action, I want to dynamically add a view (within MvxViewController) to the subviews collection of a CollectionView. Here's what I'm doing:
Does NOT work: SubviewThree inherits MvxViewController
var mvxViewController = new SubviewThree(); // SubviewThree inherits MvxViewController
var uiView = mvxViewController.View;
uiView.ClipsToBounds = true;
uiView.Hidden = false;
uiView.Frame = new RectangleF(0, 0, 320, 200);
CollectionView.AddSubview(uiView);
CollectionView.BringSubviewToFront(uiView);
Works: SubviewThree inherits UIViewController
var mvxViewController = new SubviewThree(); // SubviewThree inherits UIViewController
var uiView = mvxViewController.View;
uiView.ClipsToBounds = true;
uiView.Hidden = false;
uiView.Frame = new RectangleF(0, 0, 320, 200);
CollectionView.AddSubview(uiView);
CollectionView.BringSubviewToFront(uiView);
Works:
var label = new UILabel(); // All simple controls work just fine
label.Text = "Test Label";
label.ClipsToBounds = true;
label.Hidden = false;
label.Frame = new RectangleF(0, 0, 320, 200);
CollectionView.AddSubview(label);
CollectionView.BringSubviewToFront(label);
What's the best way to achieve this in MvvmCross? Note that I cannot use data binding (and add it via view model's ObservableCollection) here since the view to be added depends on user action - it may not be of same type.
Here's what I'm trying to do:
On right/left button touch, I want to swap views. The views are bound to different view models. The swapped view can either be either of V1 type (having a bar and another UIView) or some other type (just a UIView).
Here's my github link with sample project, just in case if the above image is not clear. You can just run the app and click on Add button. The code for adding view to subview is in BarCell.cs, line 158. There I've commented the above mentioned lines of code.

In order for MvvmCross to create a View and to hook it up with it's ViewModel, MvvmCross uses a MvxViewModelRequest object. In iOS this is connected to the View using a Request property.
You can hook this up yourself if you want to - it's just a get/set property that has to be set before ViewDidLoad occurs - see IMvxTouchView.cs
Alternatively:
if you want MvvmCross to create the View (including doing the ViewModel-View lookup) then there are some extension methods in https://github.com/slodge/MvvmCross/blob/v3/Cirrious/Cirrious.MvvmCross.Touch/Views/MvxCanCreateTouchViewExtensionMethods.cs
if you don't need a viewController, then the MvxView class may be sufficient for you - see the N=32 video for an example of its use - http://slodge.blogspot.co.uk/2013/06/n32-truth-about-viewmodels-starring.html
