How do I scale my app to new retina 4.5 resolution (1136x640)?
I have existing xibs and storyboard (non-xib) based applications, and can't find any information about how to auto-scale to new resolution.
Please, give me any links on developer.apple.com or themes on stackoverflow or any other help.
Thanks!
Apple has given the Auto Layout mechanism to allow current and future versions of apps to scale to any size (for both iOS and OSX). I would recommend you check out the Cocoa Auto Layout Guide as your first port of call.
Apple has also shared a few developer talk videos from WWDC 2012 which explain the Auto layout mechanism in a tutorial screencast manner (valid developer account needed)
