FBSession checkThreadAffinity

Question

I have used facebook authentication via facebook's SDK. If fbaccount is available then it's working fine but in the absent of fbaccount it crashes with this error:

FBSession checkThreadAffinity

I am using this code for the auth process

Please check what I am doing wrong in above code.

Answer 1

I had the same issue. The problem was that I was trying to call methods om the [FBSession activeSession] or any FBSession static method from another thread. My conclusion is that the FBSession object is not thread safe.

I cannot find any issue in your code. However, check when you first call the FBSession object, is it called from the main thread? If its not, that could be the cause.
