FBSDKLoginManager logInWithPublishPermissions always returns isCancelled=YES

Question

I am having trouble figuring out how to log a user into my app. [FBSDKAccessToken currentAccessToken] is nil, so I am calling:

[[[FBSDKLoginMana         


        

Answer 1

Also, make sure you are not calling for FBSDKAccessToken.currentAccessToken INSIDE your didFinishLaunchingWithOptions method. The setup in didFinishLaunchingWithOptions needs to complete so the token can initialize before you try to log in to Facebook.

Answer 2

Since FBSDKLoginKit 4.6.0, the logInWithReadPermissions and logInWithPublishPermissions methods of FBSDKLoginManager seems to have additional fromViewController argument and use that to present modals.

I was calling logInWithPublishPermissions inside the callback of logInWithReadPermissions, which at that point the modal is not fully dismissed yet. (I know it's a bad practice to ask permission when it's not needed, but in my case this seems to be the right place to do.) This cause it to fail with isCancelled equals to YES. I added some delay and wait for the modal to be fully dismissed fixed the problem.

Answer 3

You should try adding in your AppDelegate didFinishLaunchingWithOptions :

return [[FBSDKApplicationDelegate sharedInstance] application:application
                                    didFinishLaunchingWithOptions:launchOptions];

This would get u [FBSDKAccessToken currentAccessToken] when user is logged in.

and

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {
    return [[FBSDKApplicationDelegate sharedInstance] application:application
                                                          openURL:url
                                                sourceApplication:sourceApplication
                                                       annotation:annotation];
}

If this method is not present into AppDelegate then it results into cancelled state.

I had the same problem when I landed here, turns out I was only using the deprecated application openURL method because i was using google sign in too. To support iOS 8 and before you have to implement both the current and the deprecated method:

func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {
    return GIDSignIn.sharedInstance().handle(url, sourceApplication: options[UIApplicationOpenURLOptionsKey.sourceApplication] as! String!, annotation: options[UIApplicationOpenURLOptionsKey.annotation]) || FBSDKApplicationDelegate.sharedInstance().application(app, open: url, sourceApplication: options[UIApplicationOpenURLOptionsKey.sourceApplication] as! String, annotation: options[UIApplicationOpenURLOptionsKey.annotation])
}

func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -> Bool {
    return GIDSignIn.sharedInstance().handle(url, sourceApplication: sourceApplication, annotation: annotation) || FBSDKApplicationDelegate.sharedInstance().application(application, open: url, sourceApplication: sourceApplication, annotation: annotation)
}

The deprecated is the second.

Note: The FBSDK method is added after the google one with an or "||" operator but the order doesn't matter and if you wanna only use facebook method just erase the method and the or operator.

Note 2: As swift 3 still stabilizing the method name can change I suggest you always use the auto complete from XCode when overriding and implementing a delegate's method.

Hope this Helps o/

Answer 5

(BOOL)application:(UIApplication *)application
            openURL:(NSURL *)url
            options:(nonnull NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options
{
    return [[FBSDKApplicationDelegate sharedInstance] application:application
                                                          openURL:url
                                                          options:options];
}

// **Still need this for iOS8**
- (BOOL)application:(UIApplication *)application
            openURL:(NSURL *)url
  sourceApplication:(nullable NSString *)sourceApplication
         annotation:(nonnull id)annotation
{
    return [[FBSDKApplicationDelegate sharedInstance] application:application
                                                          openURL:url
                                                sourceApplication:sourceApplication
                                                       annotation:annotation];
}
