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

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 *)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];
             }
         }];
    } }
