Creating Universal UI files

Question

Is there any tutorial available for creating Universal UI which can run on iPad as well as iPhone on different resolution. I tried looking in the official documentation, but couldn't find anything about UI files.

Answer 1

I notice you've tagged this question with Marmalade, so I'm assuming you are talking about how to write a Universal app in Marmalade? If so then creating a Universal UI is pretty much up to you to implement in the best way you see fit.

By default all Marmalade apps are Universal apps, though you can limit to iPad only with the MKB setting iphone-ipad-only.

Marmalade does come with the iwui module that allows you to lay out user interfaces with buttons and text boxes etc. but ultimately unless you have a very simple UI you'll need to either provide different UI layouts for each screen resolution/orientation you wish to support, or do some fancy laying out in code.

Apple wisely chose to persuade developers into creating separate UIs for iPhone and iPad since the one-layout-fits-all approach generally looks bad at any screen size.
