I have an app perfectly designed for iPhone 4s and 5s. But I am worrying about Retina 3.5 and 4 displays.
I am using xib ie; Retina 4 in iPhone, I am running in simulator or iphone 5s with retina 4 .
But UIElements are missing while running the program in Retina 3.5.
How to make the app compatible for Retina 3.5 and 4
