facebook sdk logout issue for ios

Question

I am using facebook sdk for ios for the first time. I have been facing a weird problem. The facebook sdk lets me logout but wont let me login with a different user. do you guys have any idea how to solve this.

I am pasting something that i have used for logout..

- (IBAction)buttonTouched:(id)sender
{
  // If the session state is any of the two "open" states when the button is clicked
  if (FBSession.activeSession.state == FBSessionStateOpen
      || FBSession.activeSession.state == FBSessionStateOpenTokenExtended) {

    // Close the session and remove the access token from the cache
    // The session state handler (in the app delegate) will be called automatically


      NSHTTPCookie *cookie;
      NSHTTPCookieStorage *storage = [NSHTTPCookieStorage sharedHTTPCookieStorage];
      for (cookie in [storage cookies])
      {
          NSString* domainName = [cookie domain];
          NSRange domainRange = [domainName rangeOfString:@"facebook"];
          if(domainRange.length > 0)
          {
              [storage deleteCookie:cookie];
          }
      }






    [FBSession.activeSession closeAndClearTokenInformation];

  // If the session state is not any of the two "open" states when the button is clicked
  } else {
    // Open a session showing the user the login UI
    // You must ALWAYS ask for public_profile permissions when opening a session
    [FBSession openActiveSessionWithReadPermissions:@[@"public_profile"]
                                       allowLoginUI:YES
                                  completionHandler:
     ^(FBSession *session, FBSessionState state, NSError *error) {

         [[FBRequest requestForMe] startWithCompletionHandler:^(FBRequestConnection *connection, NSDictionary<FBGraphUser> *user, NSError *error) {
             if (error) {
                 NSLog(@"error:%@",error);
             } else {

                 NSLog(@"user dictionary %@",user);
                 // retrive user's details at here as shown below
                 NSLog(@"FB user first name:%@",user.first_name);
                 NSLog(@"FB user last name:%@",user.last_name);
                 NSLog(@"FB user birthday:%@",user.birthday);
                 NSLog(@"FB user location:%@",user.location);
                 NSLog(@"FB user username:%@",user.username);
                 NSLog(@"FB user gender:%@",[user objectForKey:@"gender"]);
                 NSLog(@"email id:%@",[user objectForKey:@"email"]);
                 NSLog(@"location:%@", [NSString stringWithFormat:@"Location: %@\n\n",
                                        user.location[@"name"]]);

             }
         }];

       // Retrieve the app delegate
       AppDelegate* appDelegate = [UIApplication sharedApplication].delegate;
       // Call the app delegate's sessionStateChanged:state:error method to handle session state changes
       [appDelegate sessionStateChanged:session state:state error:error];
     }];
  }
}

I am getting a text "You have already authorized Myappname" logging in for the second time after logout. But i am not getting the option for other users to get logged in.

Any help will be appreciated. Thanks in advance.

There is no session like in Websites in ios so you have to log out from Facebook account from safari and than you can again login. as i understand from your question i answered.
