I find paragraph 2.10 of App store review guidelines a bit ambiguous. It says : "iPhone Apps must also run on iPad without modification, at iPhone resolution, and at 2X iPhone 3GS resolution"
My app is deployment target is iphone and the supposed device orientation is portait
When I tested my app on ipad simulator it looks as follows:
This is just a piece of the view to give you the notion of how it actually look like - the app view does not fit the whole frame of ipad simulator.
The reason why I got my app rejected is completely different, however I don't want to waste another 8 days to see the rejection again because of some weird issue, so that's why I ask. Moreover, do you know if they stop review when they encounter a problem? Or they always undeline all the issues? My question is: should I do something with this ipad view even if my app's target device is iphone? If yes, what do you suggest me to do?
Thanks in advance
iPad will be able to download your iPhone app and run it, but your app won't be fully compatible with it. iPad users may encounter issues such as bugs and incompatible features.
iPad users will only be able to download your app from the App Store by searching its name and filtering the search results with "iPhone Only". Therefore don't expect full visibility.
Your iPhone app will run successfully on an iPad most of the times but it will be presented with a scaled screen.
