I am new in Xamarin iOS development and one thing bugs me.
In storyboard, when I select "view as Iphone 4s" and select UIViewController, in Layout tab of Properties window, it have width of 320px.
Actually every iPhone have 2x smaller width of UIViewController then it is shown on this link: http://www.iphoneresolution.com/
Iphone 6 plus is exception - it has 3x smaller width.
Please look at attached screenshot.
P.S. auto layout and use size classes are turned off in storyboard.
