ios - Facebook request for friends returns 0 friends when session is open -

i building ios application connected facebook. got of facebook related code (pretty copied of it) tokencachehowto project. have run 2 problems, 1 had simple fix, think may causing second problem.

at first login wasn't persisting. had copied code tokencachehowto, confused why , looked solution. found question , said if removed @[@"basic_info"] permissions parameter work. , did. still confused why work. note: removed @[@"basic_info"] opensessionwithallowloginui method in app delegate.

my problem want list of users friends, following request in app delegate.

fbrequest* friendsrequest = [fbrequest requestformyfriends]; [friendsrequest startwithcompletionhandler: ^(fbrequestconnection *connection,                                               nsdictionary* result,                                               nserror *error) {     nslog(@"under");     nsarray* friends = [result objectforkey:@"data"];     nslog(@"found: %i friends", friends.count); }]; 

this code outputs found: 0 friends within app delegate, if put code in same place in tokencachehowto outputs found: x friends x actual number of friends. confusing me because able users information such id , name facebook , store on server.

i realize there simple solution don't have grasp of facebook sdk yet , i'm stuck.

try working fine me , ensure permissions like

nsarray *array = [nsarray arraywithobjects:@"user_friends", nil]; 

and fetch friend

-(void)getfriendlist   {     fbrequest* friendsrequest = [fbrequest requestwithgraphpath:@"me?fields=friends.fields(first_name,last_name)" parameters:nil httpmethod:@"get"];     [friendsrequest startwithcompletionhandler: ^(fbrequestconnection *connection,                                                   nsdictionary* result,                                                   nserror *error) {         nsdictionary* friendsdic = [result objectforkey:@"friends"];         nsarray *friends = [friendsdic objectforkey:@"data"];         (nsdictionary *friend in friends) {             nslog(@"firstname %@",friend[@"first_name"]);             nslog(@"last name %@",friend[@"last_name"]);         }      }]; }
