I have a simple iPhone app, mostly table views, map views and other standard stuff. When I change the project settings to make it universal, everything works fine after a few small tweaks. So the iPad version looks just as a big iPhone app.
Definitely, the app will look better if I use some split views, pop-ups and generally rework the UI to look better on the iPad. But I wonder – will Apple review team accept a universal app that is basically just an enlarged version of the iPhone app?
Btw, I’ve submitted the app without any changes, and it was accepted without any problems.
