Description John Hair 2014-07-19 08:59:15 UTC
public class MainTabbedPage: TabbedPage
        public MainTabbedPage()
            Title = "Main";
            // The value of Thickness.Top is ignored in iOS, TabbedPage is instead using the value from Right for the Top thickness
            Padding = new Thickness(10, 20, 10, 0);
Comment 1 John Hair 2014-07-19 09:21:35 UTC
Thickness is also broken after rotating
Comment 2 Sadik Ali 2014-08-19 08:13:44 UTC
I have checked this issue  but I am unable to reproduce this issue.

I have created a Xamrin.Form application on XS and added a TabbedPage on shared project and set the iOS project as  "Set as Startup Project". I have also rotate the screen of simulator and observed that   "thickness" is not broken.

Could you please provide a sample application and build information? So, that we can reproduce this issue.
