Apple rejected app 10.6 because Facebook opens Safari to login

Answer 1

Apple review Guidelines says here

5.1.1 Data Collection and Storage

(ii) If your app doesn’t include significant account-based features, let people use it without a log-in. Apps may not require users to enter personal information to function, except when directly relevant to the core functionality of the app or required by law. If your core app functionality is not related to a specific social network (e.g. Facebook, WeChat, Weibo, Twitter, etc.), you must provide access without a login or via another mechanism. Pulling basic profile information, sharing to the social network, or inviting friends to use the app are not considered core app functionality.

I've a published app that has an optional login feature without any "account-based features".

I think providing a "continue as guest" option will fix the issue.

Answer 2

This means that your app didn't implement another feature of Facebook anywhere else in your application, if you're asking for explanation. If you make an app that just has Facebook's Log-in API, but nothing else, then your app will be rejected. Find another feature of Facebook (such as sharing or invites) that you can implement somewhere in your application, and try again.
