Icons and splash in ios and wp8

I am creating ionic applications 1.2 in Visual Studio 2015. To try to publish my application I copied my icon (192x192) and my splash screen (2048x2048) to the directory “res” the root of my application and ran the “ionic resources”. went wrong.
I copied to the folder “resources” and it worked.
I generated the android application and it worked perfectly.
I generated the application both iOS and WP8 and the images were not loaded.
I follow the tutorials from the ionicframework.com site

what did I do wrong?
