iOS Facebook SDK Error Domain com.facebook.sdk Code 2 and Code 7

Question

I am developing the application which allow user to login via Facebook (using Facebook SDK for it). The error appears when a user has already logged in Facebook in iPhone se

Answer 1

I think that these codes are vague enough that there will be lots of different things.

In the end I found that the problem was that my app bundle ID hadn't been updated when I had prepped my app for the app store. Login in to your Facebook developers account and make sure the app ID is correct.
