Creating Retina capable app icons and images
I've just added the new iOS7 widgets, and dragged across the app icon. First thing I wanted to do was add an image to the icon to get it looking slick. When I added a 114px image (retina size) it was obviously too large, and there were no controls to change this size.
I replaced it with a 57px (non-retina) image background (which worked), but it looks terrible when previewing on the iPhone.
Is there a way to import retina & non-retina images to get around this (and still have the prototypes work on both retina and non-retina devices)?
