How do I limit an iOS app only to 4 inch screen devices?

Question

Is there a setting in Xcode that lets me declare that my app only supports 4" screen devices (iPhone 5 and the newest iPod Touch)?

Answer 1

Nope.

Because iOS 7 supports devices with 3.5" screens, you can't use the only-support-iOS-x technique.

Also, there isn't a setting in Xcode or a key for requiredDeviceCapabilities which allows you to make the app 4-inch only.
