FBConnect iOS SDK publish_action 问题

Question

我必须说我现在感觉自己像个白痴。 :) 我一直在 Facebook、Google 和 StackOverflow 上上下下，但仍然无法得到我做错了什么的答案！ :) 我查看了两个 Facebook 示例：Hackbook 和 WishList。 Wishlist 显然应该告诉我该怎么做，但是 ALL 我见过的示例将 OBJECT 部分作为 URL。我不一定希望这样，因为我只想在帖子中说（此用户）正在玩 [MyGame]。

好的，这是我的目标。我有一个 iPhone 游戏。当你听一首歌时，我想做 Spotify 所做的事情，它会发布到时间线和自动收报机上。我还想用它在用户的时间轴和股票代码上发布玩家的分数。

我使用名为 Play 的操作和名为 Game 的对象及其聚合器来设置 Open Graph。我想我还需要一个名为 Score 的操作？

无论如何，我可以使用feed 对话框成功地发布到用户的墙上，但这不是我想要的Play 操作。

这是我到目前为止所得到的简明版本，非常感谢任何帮助：

夫妻注意事项： 我有一个单身人士FacebookInfo，负责处理 Facebook 代表和其他事情。我还有一个FacebookUser 类，它保存当前会话的当前用户信息，在调用me 时填充。我还有一个 DLog 方法，它只在调试模式下执行 NSlog。

当用户在我的游戏中点击Play 按钮时，我想在下面调用我的方法[[Facebook sharedInfo] publishAction:@"play"]。我将NSString 作为操作传递，所以稍后我可以调用相同的方法并使用Score 之类的操作，然后相应地修改帖子。

    Facebook *_facebook;
    FacebookUser *_facebookUser;

哇，我知道这是一篇很长的帖子，但我希望有人能帮助我指出正确的方向。

更新 1：（2012/18/02）

好的。所以我决定制作一个包含我不想做的 og 元数据的页面，并为我的对象提供 url。根据 FB 文档，找到 here:

开放图形力学

当用户在您的应用程序中执行操作时，例如烹制 Stuffed Cookie，应用程序会调用 Graph API 来创建新的烹制操作，将用户与 Stuffed Cookie 对象联系起来。这是通过使用配方对象的 URL 向用户的 /me/myapp:cook 连接发出 HTTP POST 来完成的。然后，Facebook 将抓取对象 URL，读取元数据，并通过操作将对象连接到用户的 Graph。

下图说明了这个过程：

用户在应用程序中执行操作，例如“烹饪”“食谱”
应用调用 Graph API /me/action:object=Object_URL
Facebook 将抓取对象 URL，读取其元标记并通过操作将对象连接到用户的 Graph。

如果我们可以在应用程序本身中将这些东西定义为我不需要网站的情况的参数，那就太酷了。

截至 2012 年 4 月 21 日，Facebook 要求您创建一个页面以获取所需数据。
