如何在iphone中以编程方式使用fbrequest在facebook好友墙上发帖？

我搜索了每一个地方，但没有得到一个提示如何做到这一点…我也得到了一些代码，但它不工作。。。有人能给我推荐一些教程或示例代码吗！！！提前谢谢 我正在尝试以下代码：：

-(void)inviteFriend:(CustomButton *)sender
{

    NSString *str=[NSString stringWithFormat:@"%@/feed",sender.inviteUserId];
    if (FBSession.activeSession.isOpen)
    {
        //UIImage *image = [UIImage imageNamed:@"testImage.png"];

        hudApp = [MBProgressHUD showHUDAddedTo:self.view animated:YES];
        hudApp.labelText = @"Page Sharing...";
        [self performSelector:@selector(timeout:) withObject:nil afterDelay:60*5];

        // NSString *fbMessage = [NSString stringWithFormat:@"test"];
        NSString *fbMessage = @"hello testing";


        NSMutableDictionary* params=[NSDictionary dictionaryWithObjectsAndKeys:fbMessage, @"message", FBSession.activeSession.accessToken, @"access_token", nil];

        NSLog(@"feed::%@",str);

        [FBRequestConnection startWithGraphPath:str
                             parameters:params
                             HTTPMethod:@"POST"
                      completionHandler:^(FBRequestConnection *connection, id result,NSError *error) {
                                  NSLog(@"result::%@",result);


                 if(error)
                 {
                  NSLog(@"fail : %@",error.localizedDescription);
                hudApp.labelText = [NSString stringWithFormat:@"%@",error.localizedDescription];
                                  }
                                  else
                                  {
                                      NSLog(@"Success facebook post");
                                      hudApp.labelText = [NSString stringWithFormat:@"Success"];
                                      // txtView.text = @"success";
                                      NSLog(@"success");
                                  }

                                  hudApp.mode = MBProgressHUDModeCustomView;
                                  [self performSelector:@selector(dismissHUD:) withObject:nil afterDelay:1.0];
                              }];
    }
    else
    {
        NSArray *permissions = [NSArray arrayWithObject:@"publish_stream"];
        [FBSession openActiveSessionWithPermissions:permissions allowLoginUI:YES
                          completionHandler:^(FBSession *session, FBSessionState state,NSError *error) {
                                      NSLog(@"session.permissions ? : %@", session.permissions);
                                      [self sessionDoneForPageShare:session state:state error:error withuserid:str];
                                  }
         ];
    }


}

要想贴到朋友的墙上，你需要向

/{friend\u id}/feed

发出请求。然而，Facebook：

删除通过Graph API发布到朋友墙的功能

我们将删除通过图表发布到用户朋友墙上的功能 应用程序编程接口。具体来说，针对[user\u id]/feed的帖子，其中[user\u id]是 与会话用户或stream.publish调用不同，其中 目标用户与会话用户不同，将失败。如果你 要允许人们发布到朋友的时间表，请调用 “提要”对话框。通过用户提及或标记包含朋友的故事 动作标签将显示在朋友的时间线上（假设 朋友批准标签）。有关更多信息，请参阅此博客文章
