ios - Getting all the user's friends that are using the app -

i know title question has been asked lot, new facebook 4.0 sdk problem.

i know if call

[self fcmsendopengraphrequestwithpath:@"me/friends" andcompletionhandler:^(bool seccess, id result, nserror *error) {     if (seccess) {          }     }else{      } }]; 

i user's friends using app , fit 1 paging page (i have noticed 1 page can hold 25 friends).

my problem happens when need page 2,3,4..etc'? know if call graph call 'next' field next page. because facebook sdk uses completionhandlers using recursion won't work, , don't want hard code method call obviously.
