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

This can happen when your Facebook App doesn't have "publish_actions" permission, or you're not using a test user.

On Facebook, go to manage your app, then make sure that the Facebook user you're using is defined under "Roles" as an admin or tester.

If it's not a test user or admin - Facebook will require "publish_actions" permission to be reviewed and approved before allowing your app to use it, until then you'll receive a "isCancelled=YES" result.

After testing your app with this permission, it is possible to submit this permission for review, you'll need to upload a binary that demonstrates usage of this permission with exact details on how to use it. After it's approved, you'll be able to use it with non-test Facebook users.

Answer 2

call this methord,

FBSDKLoginManager *loginManager = [[FBSDKLoginManager alloc] init];
[loginManager logInWithReadPermissions:@[@"user_friends"] handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) {
   code
}];

Answer 3

FBSDKLoginManagerLoginResult.isCancelled is unexpectedly YES:

The SDK will report a cancellation if the user explicitly taps a cancel button in the login dialogs, or if they manually app switch back to your app (known as an implicit cancellation). You should make sure you are not initiating a login flow as part of your app delegate's lifecycle (such as starting a login inside application:openURL:sourceApplication:annotation:) as that will mimic an implicit cancellation. If you must, dispatch the login initiation later to the main queue so that the app delegate's lifecycle completes first.

Answer 4

This method works in iOS 9

// Facebook Login Completion delegate
- (void)loginButton:(FBSDKLoginButton *)loginButton didCompleteWithResult:(FBSDKLoginManagerLoginResult *)result error:(NSError *)error
{
    if (result){
        NSLog(@"%@",result);
        NSLog(@"%@",result.grantedPermissions);
       [self getFacebookData:result];
     }
}  

- (void)getFacebookData:(FBSDKLoginManagerLoginResult *)result{

   if (![result.grantedPermissions containsObject:@"email"])
   {
      FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];
      login.loginBehavior = FBSDKLoginBehaviorWeb;
      [login logInWithReadPermissions:@[@"email"] fromViewController:self handler:^(FBSDKLoginManagerLoginResult *result, NSError *error)
       {
         if (error)
         {
             // Process error
         }
         else if (result.isCancelled)
         {
             // Handle cancellations
         }
         else
         {
             if ([result.grantedPermissions containsObject:@"email"])
             {
                 NSLog(@"result is:%@",result);
                 if ([FBSDKAccessToken currentAccessToken]) {
                     [[[FBSDKGraphRequest alloc] initWithGraphPath:@"me" parameters:@{@"fields": @"first_name, last_name, email, id"}]
                      startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
                          if (!error) {
                              NSLog(@"fetched user:%@", result);
                              [self registerWithFacebook:result];
                          }else{
                              NSLog(@"%@",error);
                          }
                      }];
                 }


             }
         }
     }];


 }else{
    if ([FBSDKAccessToken currentAccessToken]) {
        [[[FBSDKGraphRequest alloc] initWithGraphPath:@"me" parameters:@{@"fields": @"first_name, last_name, email, id"}]
         startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
             if (!error) {
                 NSLog(@"fetched user:%@", result);
                 [self registerWithFacebook:result];
             }else{
                 NSLog(@"%@",error);
             }
         }];
    }
}

}

NOTE : Use FBSDKLoginBehaviorWeb instead of FBSDKLoginBehaviorBrowser. This will surely work

Answer 5

I also faced the same issue and i spent almost 2 hours to resolve the issue. What i did is

FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];
**[login logOut];** // adding this single line fixed my issue
[login logInWithReadPermissions: @[@"public_profile"] fromViewController:self  handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) {
     if (error) {
         NSLog(@"Process error");
     } else if (result.isCancelled) {
         NSLog(@"Cancelled");
     } else {
         NSLog(@"Logged in");
         [self GetData];
     }
 }] // I called this logout function 

and the issue was fixed

i was using both google and Facebook login so i had to implement my openURL method like this, iOS 9+

- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options {
    if ([[url absoluteString] containsString:@"YOURFBID"]) {
        return [[FBSDKApplicationDelegate sharedInstance] application:app openURL:url options:options];
    } else {
        return [[GIDSignIn sharedInstance] handleURL:url
                                   sourceApplication:options[UIApplicationOpenURLOptionsSourceApplicationKey]
                                          annotation:options[UIApplicationOpenURLOptionsAnnotationKey]];
    }
    return NO;
}

// you can perform further any operations using the access token

- (void)GetData {
    if ([FBSDKAccessToken currentAccessToken]) {
        NSDictionary *AccessToken = [FBSDKAccessToken currentAccessToken];
        [[[FBSDKGraphRequest alloc] initWithGraphPath:@"me" parameters:@{@"fields": @"id, name, first_name, picture.type(large) ,last_name"}]
         startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
             if (!error) {
                 //NSLog(@"fetched user:%@", result);
                 //NSDictionary *Result = result;
                 NSDictionary *params = [NSMutableDictionary dictionaryWithObject:[AccessToken tokenString] forKey:@"access_token"];

             } else {
                 [self showAlertController:@"Error" message:error.localizedDescription];
             }
         }];
    } }

Answer 6

1.check already added

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

2.check already added

- (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];
}

3. write this statement [FBSDKProfile enableUpdatesOnAccessTokenChange:YES]; before

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

4.call logInWithReadPermissions method in dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(1 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{}
