Facebook login using Parse not working

Question

I am trying to use Parses SDK to make the single sign on for Facebook but when I press the login button I get this error:

Uh oh. An error occurred: Error Domain=com.facebook.sdk Code=2 "The operation couldn’t be completed. (com.facebook.sdk error 2.)" UserInfo=0x1d5bac20 {com.facebook.sdk:ErrorLoginFailedReason=com.facebook.sdk:SystemLoginDisallowedWithoutError, com.facebook.sdk:ErrorSessionKey=, expirationDate: (null), refreshDate: (null), attemptedRefreshDate: 0001-12-30 00:00:00 +0000, permissions:(null)>}

The code when I hit the button is almost the same as in Parse's tutorial

- (IBAction)loginButtonTouchHandler {
    // The permissions requested from the user
    NSArray *permissionsArray = @[ @"user_about_me", @"user_birthday"];

    // Login PFUser using Facebook
    [PFFacebookUtils logInWithPermissions:permissionsArray block:^(PFUser *user, NSError *error) {
        [_activityIndicator stopAnimating]; // Hide loading indicator

        if (!user) {
            if (!error) {
                NSLog(@"Uh oh. The user cancelled the Facebook login.");
            } else {
                NSLog(@"Uh oh. An error occurred: %@", error);
            }
        } else if (user.isNew) {
            NSLog(@"User with facebook signed up and logged in!");
        } else {
            NSLog(@"User with facebook logged in!");
        }
    }];
}

I have my facebook app all set and everything.

Any leads?

I had the same problem on my device. Same error.

Fix was simple: Settings -> Privacy -> Facebook -> and check your app status there.

You need to do this on your device (iPhone/Simulator) – Sjoerd Perfors Jul 29 '13 at 14:39

for those who are still getting the error, check if the bundle id of the app is the same entered at the facebook app. – Andre Cytryn Mar 01 '14 at 16:39
Fantastic. Somehow, the privacy setting was 'off' and that caused the error. Must warn the user about that...! – fatuhoku Jan 14 '15 at 16:53

I had the same problem on one device (iPhone 5S). The Settings -> Privacy -> Facebook were correct. I had other devices along with the iPhone sim which all worked fine.

Anyway, I tried rebooting which did not fix the issue, also to delete the app and reinstall.

What finally worked was the following:

Turn off the access for the app under Settings -> Privacy -> Facebook.
Try logging into FB from the app. (which fails of course).
Re enable access for the app setting under Settings -> Privacy -> Facebook.
Try logging into FB from the app which now succeeded.

Strange error.

Hope this helps someone.

See the answer below. Sometimes strangely enough the switch is turned on. It helps to relogin with Facebook in System preferences.

Pass an empty permissions array NSArray *permissionsArray = @[];

Make sure your permissions are set in your facebook app console.

I removed my FB access Key and secret from the parse backend and it worked great.

( Parse bug??)

Please makesure you for add at AppDelegate.m

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {

     return [[FBSDKApplicationDelegate sharedInstance] application:application openURL:url sourceApplication:sourceApplication annotation:annotation];
}

and add

[FBSDKAppEvents activateApp];

- (void)applicationDidBecomeActive:(UIApplication *)application {
    [FBSDKAppEvents activateApp];
}

To make it work on Swift 3.1 and iOS 10.3.1, make sure that you have following methods in your app delegate:

Just for Swift 3.1:

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
  let configuration = ParseClientConfiguration {
       $0.applicationId = "XXXXX"
       $0.clientKey = "XXXXXX"
       $0.server = "https://yourserverparse.."
   }

   Parse.initialize(with: configuration)
   PFFacebookUtils.initializeFacebook(applicationLaunchOptions: launchOptions)

   return FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
}

And than:

 func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {

    var isHandled:Bool;

    if #available(iOS 9.0, *) {
        isHandled = FBSDKApplicationDelegate.sharedInstance().application(app, open: url, sourceApplication: options[.sourceApplication] as! String!, annotation: options[.annotation])
    } else {
        // Fallback on earlier versions
        isHandled = FBSDKApplicationDelegate.sharedInstance().application(app, open: url, options: options)
    }

    return isHandled
}

And than:

func applicationDidBecomeActive(_ application: UIApplication) {
    FBSDKAppEvents.activateApp()
}
