i'm using latest fbsdk v4.3 using login version v2.3.

i need stop , close current active session couldn't able find out fbsession class , corresponding methods.

can please me out rid of issue when user taps on facebook provided logout button can stop , close current active session.

i tried below code throwing me error 'unknown type name 'fbsession'.

fbsession *session = [session activesession]; [session closeandcleartokeninformation]; [session close]; [fbsession setactivesession:nil];

in v4.x of facebook sdk can use new fbsdkloginmanager class , call logout method have same effect.

in background calls [fbsdkaccesstoken setcurrentaccesstoken:nil] remove access token , resets facebook profile cached in fbsdkprofile
