How to target a specific iPhone size when developing in Xcode 6.1

I've built my 4 inch screen and 3.5 inch screen apps in Xcode 5.1.1. Yesterday I downloaded Xcode 6.1 to build those same apps for iPhone 6 and 6+. I'm not using auto layout (because it messes with my UIImageViews) and to use size classes you must also use auto layout. So I can't use size classes either. When I use that 1 storyboard for 4.7inch and 5.5 inch iPhone storyboards that are in Assistant Editor, i want to move an image in only 4.7 inch but instead the image moves in both 4.7 inch and 5.5 inch iPhones. How do I make it that the image moves only in 4.7 inch instead of both?
