Getting null values in FB request response dictionary

I am trying to fetch all list of albums in a logged in facebook account with the following code... But unfortunately i am not able to get any list at all th result is dictionary..is like

{
    data =     (
    );
}

Any idea what i did wrong in the below code...

 FBRequest* friendsRequest = [FBRequest requestForGraphPath:@"me/albums"];

   [friendsRequest startWithCompletionHandler: ^(FBRequestConnection*connection,NSDictionary* result,NSError *error) {
                                                          if(!error)

                                                       {
                                                              NSLog(@"%@",result);
                                                              //NSArray *albums;


                                                          }

Here is the full method

- (BOOL)retrieveFacebookPhotosWithCompletionBlock:(void (^)(NSArray *, NSError *))completionBlock
{
    //FBSession *activeFBSession=[FBSession activeSession];

    //activeFBSession.state;


    [FBSession openActiveSessionWithReadPermissions:nil
                                       allowLoginUI:YES
                                  completionHandler:^(FBSession *session,
                                                      FBSessionState state,
                                                      NSError *error) {
                                      if (error) {

                                          NSLog(@"Error");
                                      } else if (session.isOpen) {

                                          [[FBRequest requestForMe] startWithCompletionHandler: ^(FBRequestConnection *connection, NSDictionary<FBGraphUser> *user, NSError *error) {
                                              if (error) {
                                                  //error
                                                  completionBlock(nil, error);
                                              }else{
                                                  FBRequest* friendsRequest = [FBRequest requestForGraphPath:@"me/albums"];

                                                  [friendsRequest startWithCompletionHandler: ^(FBRequestConnection *connection,NSDictionary* result,NSError *error) {
                                                      if(error)
                                                          completionBlock(nil, error);
                                                      else
                                                      {
                                                          NSLog(@"%@",result);
                                                          //NSArray *albums;


                                                      }
                                                  }];
                                              }
                                          }];

                                      }
                                  }];



        return YES;
}

Yes it is because of the permissions you have given .As mentioned above you have to give permission for accessing photos via key user_photos. Either you can refer the sample project provided by facebook SDk for more keys and the particular permissions each offer.or the facebook developer page.

To get access to photos you need user_photos permission while you open the Facebook session.Try to change the code as below.

[FBSession openActiveSessionWithReadPermissions:
[NSArray arrayWithObjects:@"user_photos",nil] allowLoginUI:YES
completionHandler:^(FBSession *session, FBSessionState status, NSError *error) {
                                         //YOUR CODE
                                           }];

you need to get permission for "user_photos" for getting the albums.

When I tried it without the permissions then I received the same response as you. Using graph api explorer

When I got new access_token with permission than I received proper response from the api.
