      andParams:params 
      andDelegate:self]; 

pero necesito para colocar en la pared de mi amigos. ¿Cómo puedo hacer esto

En este post que han mencionado sobre targetId tengo que hacer algo con eso.

Answer 1

¿Ha intentado utilizar,

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

ACTUALIZACIÓN:

Difusión en la pared de amigos ya no irán de trabajar con Graph API. En su lugar, debe usar FBDialog.

Answer 2

@mAc

Primero debe autorizar el facebook. Luego implementa los métodos 'FBRequestDelegate' para su clase. A continuación, hacer una petición con la API gráfica que se indican a continuación

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

vez que su solicitud tuvo éxito, api llamará al método delegado requestDdidLoad ',

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

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

} 

formar el resultado obtendrá el ID de la página frieds
