IOS App Store Submission Checklist - anything else to add?
I've got one you can add: iPad applications don't have to support all four orientations. However, whichever orientation you do support (in our instance, portrait) you must support the top-up and bottom-up variations unless some special circumstance warrants only supporting one or the other. Just had a submission rejected earlier this week for this reason. FYI, here is the response we received from Apple:10.1We found that your app does not comply with the Apple iOS Human Interface Guidelines, as required by the App Store Review Guidelines.Specifically, we noticed your app only supported the top-up variant of the portrait orientation, but not the bottom-up variant.While supporting both variants of both orientations, each with unique launch images, provides the best user experience and is recommended, we understand there are certain applications that must run in the portrait orientation only. In this case, it would be appropriate to support both variants of that orientation in your application, e.g., Home button up and down.Addressing this issue typically requires only a simple and straightforward code modification. However, if you require assistance, the Apple Developer Support Team is available to provide code-level assistance.For more information, please review the Aim to Support All Orientations section of the iOS Human Interface Guidelines.
