I previously used the following to clear and reset the Facebook access token
[FBSession.activeSession closeAndClearTokenInformation];
Since the update to 4.0 this no longer works. FBSession.activeSession
has changed to [FBSDKAccessToken currentAccessToken]
.
I however can't find the latest version of closeAndClearTokenInformation that works with the latest version. Any suggestions?
FBSDKLoginManager *logMeOut = [[FBSDKLoginManager alloc] init];
[logMeOut logOut];
or
[FBSDKAccessToken setCurrentAccessToken:nil];
[FBSDKProfile setCurrentProfile:nil];
to logout
Then when you login again, make sure to set:
login.loginBehavior = FBSDKLoginBehaviorWeb;
Like so:
FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];
login.loginBehavior = FBSDKLoginBehaviorWeb;
[login logInWithReadPermissions:@[@"user_friends"] handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) {
etc...
}];
I found some info in the docs saying FBSDKLoginBehaviorWeb can be used for "kiosk" apps; which I guess are apps designed to have more than one person log into them routinely.
One thing to note, this login method creates a modal UIWebView which is set up for portrait mode. I'm not sure if its possible to change this yet.
