How to develop or migrate apps for iPhone 5 screen resolution?
I have an app which was targeted for iPhone 3/3G and iPhone 4(retina) basically (using iOS SDK 5.0). Now i want to port it to iPhone 5. I have Xcode 4.5.1 installed on my machine. Most of the UI implementation is done programatically without using any Xib file.
At this stage i don't understand what to do and from where to start :(
Please help me to get an way...thanks in advance :)
I am pretty new in iOS...
