iphone - 如何在 Objective C 中将好友标记为 Facebook 中的用户帖子

Question

我正在尝试使用 Facebook Feed Dialog 发布文本和图像，我可以发布到我自己的墙上，但无法标记 friend 。我可以从 FBFriendPickerViewController 选择一个 friend ，但是当我单击完成时，我收到返回错误 5 。在 stackoverflow 的一个问题(ios-Facebook SDK 3.0 Error 5 When Posting Status Update)中，有几种方法可以导致此错误，我已经纠正了该问题中提到的所有可能的方法。

提要对话框是否正确 [FBRequestConnection startWithGraphPath:@"%@/feed"参数:params

这是我的代码，

- (IBAction)pickFriendsList:(UIButton *)sender
{
    FBFriendPickerViewController *friendPickerController = [[FBFriendPickerViewController alloc] init];
    friendPickerController.title = @"Pick Friends";
    [friendPickerController loadData];

    [friendPickerController presentModallyFromViewController:self animated:YES handler:
     ^(FBViewController *sender, BOOL donePressed) {

         if (!donePressed) {
             return;
         }

         NSString* fid;
         NSString* fbUserName;

         for (id<FBGraphUser> user in friendPickerController.selection)
         {
             NSLog(@"\nuser=%@\n", user);
             fid = user.id;

             fbUserName = user.name;

             NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:@"aaaaaa", @"message", @"http://webecoist.momtastic.com/wp-content/uploads/2009/01/nature-wonders.jpg", @"picture", @"My Susfsdfsdfs sdf sfsdfp", @"name", nil];

             NSLog(@"\nparams=%@\n", params);


             [FBRequestConnection startWithGraphPath:@"%@/feed" parameters:params HTTPMethod:@"POST"
                                   completionHandler:^(FBRequestConnection *connection, id result, NSError *error)


              {
                  //Tell the user that it worked.
                  UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Shared"
                                                                      message:[NSString stringWithFormat:@"Invited %@! error=%@", fbUserName, error]
                                                                     delegate:nil
                                                            cancelButtonTitle:@"OK"
                                                            otherButtonTitles:nil];

                  [alertView show];
                  NSLog(@"%@ alertview description",alertView.message);

              }
              ];

         }

     }];

}

错误:

Answer 1

注意:您的代码中缺少 FB 用户 ID

更改您的代码如下:

[FBRequestConnection
             startWithGraphPath:[NSString stringWithFormat:@"%@/feed", fid]
             parameters:params
             HTTPMethod:@"POST"
             completionHandler:^(FBRequestConnection *connection,
                                 id result,
                                 NSError *)

问候，
