Use this code: 

if (FBSession.activeSession.isOpen)
{
    [FBSession.activeSession closeAndClearTokenInformation];
}

Swift version

import FBSDKLoginKit

FBSDKLoginManager().logOut()

Using FBSDK 4.4

#import <FBSDKLoginKit/FBSDKLoginManager.h>

then use this code to logout.

FBSDKLoginManager *manager = [[FBSDKLoginManager alloc] init];
[manager logOut];

hope this will help :)
