Question

I am trying fetch my Friends who are using my application from facebook and but in the response i am getting empty list list. Please guide me what i am doing wrong. I am using the following code

[[FBRequest requestForMe] startWithCompletionHandler: ^(FBRequestConnection *connection, NSDictionary<FBGraphUser> *user, NSError *error) {
                if (error) {
                    //error
                    NSLog(@"%@",error);
                }else{
                    FBRequest* friendsRequest = [FBRequest requestForMyFriends];
                    [friendsRequest startWithCompletionHandler: ^(FBRequestConnection *connection,NSDictionary* result,NSError *error) {
                        NSArray* friends = [result objectForKey:@"data"];

                        NSLog(@"%@",result);

                        for (NSDictionary<FBGraphUser>* friend in friends)
                        {
                            NSLog(@"%@ %d",friend.username,[friend.id intValue]);
                        }
                    }];
                }
            }];

Possible reasons:

1) You don't have the rights to get connections of this account (wrong apikey/passkey or rights not properly set)

2) Check what is stored in "result" variable and the answer status: it may guide you in some way.

3) Finally, try to get some simpler informations (like your own username) to be sure you have access to these informations.

In the new version of Facebook's API you will get ONLY friends that installed the app (i.e. is_app_user is 1). You can't get friends who haven't logged in with your app anymore. Instead, you can get taggable_friends. This will return a list with all of your friends, but here "id" field will be different, not the real facebook id. Its only for tagging, i.e. for passing to field "tags" like:

 NSDictionary *params = @{@"message":self.invitationText.text,
                         @"tags":ids,
                         @"caption":@"...",
                         @"name":@"...",
                         @"place":@"123456789",
                         @"link":APP_STORE_URL};

[FBRequestConnection startWithGraphPath:@"/me/feed"
                             parameters:params
                             HTTPMethod:@"POST"
                      completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
                            //...
                      }];
