PFLoginViewController not showing Facebook login button with Swift

Question

Here is my Swift code:

        let loginViewController = PFLogInViewController()
        loginViewController.delegate = self;
        loginViewController.signUpController.delegate = self;
        loginViewController.fields = PFLogInFields.Facebook
        self.presentViewController(loginViewController, animated: animated, completion: nil)

I have tried everything possible, but don't know why it is not showing the Facebook login button. It just shows the default fields.

Answer 1

Check again:

1. if you have in appdelegate [PFFacebookUtils initializeFacebook]
2. you have to add, also PFLogInFieldsDismissButton
3. you must also set the facebookPermissions property to the a list of the permissions we want to be granted by the user

Example for ObjC

if (![PFUser currentUser]) {        
        // Customize the Log In View Controller
        PFLogInViewController *logInViewController = [[PFLogInViewController alloc] init];
        [logInViewController setDelegate:self];
        [logInViewController setFacebookPermissions:[NSArray arrayWithObjects:@"friends_about_me", nil]];
        [logInViewController setFields: PFLogInFieldsFacebook | PFLogInFieldsDismissButton];

        // Present Log In View Controller
        [self presentViewController:logInViewController animated:YES completion:NULL];
    }
