Doesn't follow iOS App Store Guidelines for Camera Permissions

[coderforlife]

SPECIFIC ISSUE ENCOUNTERED

Just submitted an app for review to the App Store using the SDK, and it was rejected since if the user does not grant camera permissions, the app forces the settings page to open automatically. Apparently, you are supposed to instead show a message about why it is important and give them the option to go to the permission settings page or skip (doing the same thing as the skip button does*).

SMARTPHONE (please complete the following information):

• OS
  • Android
  • iOS

EXPECTED BEHAVIOR

Denying camera permissions should not jump to the app permission settings page automatically without informing the user first.

VERSIONS USED

What version of Google Cardboard are you using?
Cardboard SDK v1.30.0

https://github.com/Marena-AB/Mindscape-360 (however, setup is not straightforward at the moment)

ADDITIONAL CONTEXT

• We also discovered that the Skip button itself doesn't work on iOS. We had to modify

  cardboard/sdk/qrcode/ios/qr_scan_view_controller.mm

  Line 224 in f9a197a

  [skipButton addTarget:nil

  from skipButton addTarget:nil to skipButton addTarget:self to get it to work at all.

We have written replacement code in
https://github.com/MoravianUniversity/Mindscape-360/blob/main/iosApp/iosApp/qr_code.mm
and
https://github.com/MoravianUniversity/Mindscape-360/blob/main/iosApp/iosApp/qr_scan_view_controller.mm
for those files which you may be able to just reuse.
