I received the following from Apple. I tried fixing the constraints for just iPad but I can get the scroll bar to come on top. How would I fix this? It is an iPhone only app. Thanks
From Apple 2. 4 PERFORMANCE: HARDWARE COMPATIBILITY Performance - 2.4.1
We noticed that your app did not run at iPhone resolution when reviewed on iPad running iOS 10.2. Specifically, we were unable to register as the sign-up option was behind the amount section.
We've attached screenshot(s) for your reference.
Next Steps
Please revise your app to ensure it runs and displays properly at iPhone resolution on iPad.
Resources
For information on iOS device screen sizes and resolutions, please see the iOS Human Interface Guidelines as well as the Points versus Pixels in the View Programming Guide for iOS.
Additional Information
If you have difficulty reproducing a reported issue, please try testing the workflow described in Technical Q&A QA1764: How to reproduce bugs reported against App Store submissions.
If you have code-level questions after utilizing the above resources, you may wish to consult with Apple Developer Technical Support. When the DTS engineer follows up with you, please be ready to provide: - complete details of your rejection issue(s) - screenshots - steps to reproduce the issue(s) - symbolicated crash logs - if your issue results in a crash log
This is not an issue with supported devices - even if the iOS app is for iPhone only, it has to run on iPhone resolution on an iPad. This is the same sizing (or very, very close) as running on a iPhone 4 simulator, based on the screenshots.
Fix the constraints for iPhone 4 and it will be approved.
I got the same issue with my app which had the Deployment Info set to iPhone. Did they attach a screenshot with their response?
The issue with mine was that the constraints weren't set up properly. On smaller screen sizes (which the 1x setting on the iPad shows) my buttons were pushed together.
Check out your build on the simulator using an iPhone 5.
I had the same issue with my app.
My application was intended for iPhone and not for iPad, but the apple review team told me this:
It would be appropriate to revise your app to ensure that it runs on iPad at iPhone resolution.
My solution:
Optimize the user interface for iPhone 4
I hope it helps.
Supported minimum iOS version is not relevant! I got rejection with iPad (1X) screenshot. App supports min version 10!
The problem is your app supports "minimum iOS version=9". it means your app must support 1x (not only2x or 3x) . Probably Apple itc review team tests the apps on ipad mini with 1x screen for iphone 4 device testing.
just optimize UI for 1x (iphone 4/4s)
I had also same issues throw me by apple. i search and got it solution to give support iPhone4 . this will resolved the issues.
Update your view constraint and give support to iphone4 or Run the app in the ipad and give support.
Simple remove suffix _iphone.storyboard or _ipad.storyboard, just may use Main.storyboard will fix this appstore issue
