I am new to iOS programming and obviously new to XCode etc as well. I create a user interface for an app and I want it to be consistent throughout all the devices. I got the job done, but it took more effort than I wanted it to, and it seems like it's pretty ineffective that I can't separate the view with percentages in the user interface editor itself.
Is it so that I am missing or must it really be programmed? If the latter, then how?
