Solução
Você já tentou usar,
[facebook requestWithGraphPath:@"[friend_ID]/feed" andParams:params andHttpMethod:@"POST" andDelegate:self];
ATUALIZAR:
A publicação no Wall Wall não funcionará mais com a API do gráfico. Em vez disso, você deve usar o fbdialog.
Outras dicas
@Mac
Você tem que autorizar o Facebook primeiro. Em seguida, você implementa os métodos 'FBRequestDelegate' para sua classe. Em seguida, faça uma solicitação com a API Graph, conforme dado abaixo
[facebook requestWithGraphPath:@"/me/friends" andDelegate:self];
Depois que sua solicitação for bem -sucedida, a API ligará para o método delegado de 'requestddidload',
-(void)request:(FBRequest *)request didLoad:(id)result {
NSLog(@"Result: %@", result);
}
Formar o resultado, você obterá o ID da página Frieds
