Parse api remove 'you already allowed this application' after the user has allowed the application

I use the parse.com login controller to register users on facebook.

if the user has allowed the application before he receives "you have already allowed this application" from facebook.

Does anyone know how to solve this?

Im code using:

PFLogInViewController *logInController = [[PFLogInViewController alloc] init];
logInController.delegate = self;
logInController.fields =  PFLogInFieldsFacebook ;
logInController.facebookPermissions = [NSArray arrayWithObjects:@"publish_stream", nil];
NSLog(@"%@",logInController.facebookPermissions);
[self.navigationController presentModalViewController:logInController animated:YES];
