Facebook authorization fails on iOS6 when switching FB account on device

Question

I\'m using die Facebook SDK 3.1.1 to implement FB Connect in my iOS application. This works fine in the simple case with either the new FB integration (logged in on iOS) or

Answer 1

I have the same problem on 3.1.3 FB SDK with iOS7.1. And I find a solution here. Hope it help!!
I have tried all answers here.
@loganathan nil permissions, @ill_always_be_a_warriors fbResync.
All of those don't work for me.

But I found it will works well when I launch the same code in iPhone 7.1 simulator
(without SSO"Single Sign On")

The same code works well on old version iOS FB SDK(not sure which version, but not 3.13)
(but no SSO will show when try to login)

So, I try to re-write a sample problem. I found several different here.
1. https://developers.facebook.com/docs/ios/getting-started Add new FacebookDisplayName
2. I modify my BundleID for iTune connect but I am not update it back to Faceboook App Dev


After modify those setting, it works on my iOS app with SSO feature.
Hope it help!!
