My problem is that I have storyboard which support multiple languages (6). Since app was created before iOS6 I have 6 versions of storyboard. Now UI has been redesign a bit (mostly order of views has been changed) and I did changes only in English version.
Now how to propagate those changes to other languages with minimum effort?
I've noticed that since iOS6 and XCode 4.5 I can get rid of multiple storyboards and just provide translated strings for other languages.
I've found this answer and this tutorial, but this refers only to new projects nothing about how to do this for old big projects.
