iOS FBConnent login popup issue

Question

I'm using FBConnect on the iOS. I tried to prevent the login popup by using: - (void)viewDidLoad {

permissions = [[NSArray arrayWithObjects:
                @"read_stream", @"offline_access", @"user_events", nil] retain];

FBtryAppDelegate *delegate = (FBtryAppDelegate*) [[UIApplication sharedApplication] delegate];

facebook = delegate.facebook;

[facebook authorize:permissions delegate:self];

}

and every time it opens the login dialog and closes itself automatically without entering the details.

I don't want the dialog appear at all if the login is already exist.

what can I do? Thanks.

You should store the access token and the expiration date first. Then, you can check if the token is saved or not. Please, refer to this SO post.
