Reset Facebook Token Reference - Facebook SDK 4.0

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.
has changed to
[FBSDKAccessToken currentAccessToken]

I however can't find the latest version of closeAndClearTokenInformation that works with the latest version. Any suggestions?

Answer Source
FBSDKLoginManager *logMeOut = [[FBSDKLoginManager alloc] init];
[logMeOut logOut];


[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) {

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.
