objective c - How to design single storyboard file that supports all iphone screen sizes?

Question

I am using storyboard and xcode 4.6 for designing Iphone app. I have very complex viewscontrollers and some of the subviews(like scrollview's and autocomplete tablviews) have generated dynamically. When app build for iphone 4 everything works fine. But, when using Iphone(retina-4 inch) simulator, I noticed that there is space at the top and bottom of the screen and also some of the subviews (like scrollviews and autocomplete tableviews ..) misplaced and covering other subviews in that viewcontroller. I tried to search and found some are suggesting to design/load two xib files based on screen size. I have enabled both autoresize masks and autolayout, but still the problem persists.

How to design a single storyboard file that is feasible for both Iphone-4 and Iphone-5.

Thanks in advance...

Answer 1

use the button in the picture below to toggle between retina 4 in and 3.5 inch. use the autosizing tool under the size inspector on the top right to get views to position themselves correctly.
