I have an app that creates graphics and I've only tested it on an iPad with retina display (screen scale of 2). Because the app heavily depends on this screen density, I'm looking for a way to exclude earlier versions of iPad, as well as iPad mini from being able to download my app from the app store.
Is there some xCode project flag or some device feature that I can use to make sure that my iOS 6.0 app would not be sold to devices which do not have retina displays?
Thank you!
