Voglio postare qualcosa nel muro degli amici degli utenti.

Io lo uso per postare nella parete utente

SBJSON *jsonWriter = [[SBJSON new] autorelease]; 

    NSDictionary* actionLinks = [NSArray arrayWithObjects:[NSDictionary dictionaryWithObjectsAndKeys: 
                  @"Always Running",@"text",@"http://itsti.me/",@"href", nil], nil]; 

    NSString *actionLinksStr = [jsonWriter stringWithObject:actionLinks]; 
    NSDictionary* attachment = [NSDictionary dictionaryWithObjectsAndKeys: 
           @"a long run", @"name", 
           @"The Facebook Running app", @"caption", 
           @"it is fun", @"description", 
           @"http://itsti.me/", @"href", nil]; 
    NSString *attachmentStr = [jsonWriter stringWithObject:attachment]; 
    NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys: 
            @"Share on Facebook", @"user_message_prompt", 
            actionLinksStr, @"action_links", 
            attachmentStr, @"attachment",nil]; 

    [facebook dialog:@"feed" 
      andParams:params 
      andDelegate:self]; 

ma ho bisogno di inserire nel mio muro amici. come posso fare questo

In questo post hanno menzionato su targetId devo fare qualcosa con quello.

Answer 1

Hai provato a usare,

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

UPDATE:

distacco su amici muro non ci sarà più lavorare con Graph API. Invece è necessario utilizzare FBDialog.

@mAc

Devi autorizzare facebook prima. Quindi implementa i metodi "FBRequestDelegate" nella tua classe. Poi fare una richiesta con il grafico API come indicato di seguito

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

Una volta che la richiesta è riuscita, api chiamerà il metodo delegato 'requestDdidLoad',

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

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

} 

Modulo il risultato che si otterrà l'ID pagina di frieds
