I believe that this is what they do (or at least, this is how I would go with it):
1) get image content of the view I want to flip with:
UIGraphics.BeginImageContext (view.Bounds.Size);
view.Layer.RenderInContext (UIGraphics.GetCurrentContext ());
var viewImage = UIGraphics.GetImageFromCurrentImageContext ();
UIGraphics.EndImageContext ();
2) then just split the view in half and place it in two UIImageViews
3) place these two views on top of your view you want to appear being flipped (folded)
4) using the view.layer.transform call the rotation transformation with pivot point exactly at the top and middle of the view, which will make it appear to flip and fold there
5) job done, have drink :-)
Cheers & happy coding.
