Answer 1

Czy próbowałeś stosując

[facebook requestWithGraphPath:@"[friend_ID]/feed" andParams:params andHttpMethod:@"POST" andDelegate:self]; 

UPDATE:

zamieszczenie na ścianie przyjaciele nie będą więcej pracować z Graph API. Zamiast tego musisz użyć FBDialog.

@mAc

Najpierw musisz autoryzować Facebook. Następnie zaimplementuj metody "FBRequestDelegate" w swojej klasie. Następnie złożyć zamówienie z wykresu API, jak podano poniżej

[facebook requestWithGraphPath:@"/me/friends" andDelegate:self]; 

Gdy wniosek udało, api wywoła metodę delegata „requestDdidLoad”,

-(void)request:(FBRequest *)request didLoad:(id)result { 

    NSLog(@"Result: %@", result); 

} 

Formularz wynik otrzymasz identyfikator strony frieds
