上传的帖子没有显示在Facebook页面墙上

Question

我正在尝试使用iOS中的图形API（page_id / photos）和Objective-C上传Facebook页面墙上的帖子，但在看到Facebook页面的响应后，我的帖子将显示在访问者帖子而不是Facebook页面壁。我尝试传递页面访问令牌广告参数并提供manage_pages，publish_pages和publish_action，但仍在帖子中显示帖子。请帮帮我。

这是我的代码：

FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc]
    initWithGraphPath:@"/me/accounts" parameters:@{@"fields":@"id,name,access_token"}
    HTTPMethod:@"GET"];
[request startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection,
         id result,
         NSError *error) {

            NSLog(@"%@",result);

            NSArray *data = [result valueForKey:@"data"];
            NSArray *fbPageAT = [data valueForKey:@"access_token"];


            NSURL *postImgURL = [NSURL URLWithString:upload_file];

            NSDictionary *params = @{
                       @"caption": _createPostTextField.text,
                       @"url": postImgURL,
                       @"access_token": [fbPageAT objectAtIndex:selectedIndex],
                    };

            FBSDKGraphRequest *r = [[FBSDKGraphRequest alloc]
                                          initWithGraphPath:[NSString stringWithFormat:@"/%@/photos",fbPageIDToPost]
                                          parameters:params
                                          HTTPMethod:@"POST"];
            [r startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection,
                                                  id result,
                                                  NSError *error) {
                NSLog(@"%@", result);
            }]; 
        }];
