Facebook and twitter login with Parse iOS only works once

Question

I\'m using the twitter and Facebook login in the Parse SDK. For every app launch I can log into each service once, but when I logout using [PFUser logOut] I am unable to log in

Answer 1

OK, I finally solved this. The problem was that in my app setup on twitter, the permissions were set to 'Read only', not 'Read and Write'.

Changing this setting solved the problem with both facebook and twitter.

Answer 2

In you logout method, you should clear the Facebook session token as well like below:

[[FBSession activeSession]closeAndClearTokenInformation];

This will clear the active Facebook session's token.
