FBConnect iOS SDK publish_action问题

Question

我必须说我现在感觉像个白痴。 :)我在Facebook，Google和StackOverflow上走来走去，仍然找不到我做错了什么的答案！ :)我已经看了两Facebook的例子： Hackbook和WishList 。 Wishlist显然是应该告诉我怎么做的人，但是我所看到的所有示例都将对象部分作为URL。 我不一定希望这样做，因为我只想发帖说（此用户）正在玩[MyGame] 。

好的，这是我的目标。 我有一个iPhone游戏。 我想做Spotify在听一首歌曲时做的事情，这首歌会发布到时间轴和股票行情指示器上。 我还想用它在用户的时间轴和股票报价中发布玩家的分数。

我用一个名为Play的动作和一个名为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的动作？

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

这是我到目前为止所获得的简洁版本，非常感谢您的帮助：

几个注意事项：我有一个单身的FacebookInfo ，负责处理Facebook委托和事物。 我还有一个FacebookUser类，用于保存当前会话的当前用户信息，并在致电给me时填充。 我还有一个DLog方法，该方法仅在调试模式下才执行NSlog。

当用户单击Play中的“ 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，因此以后我可以调用相同的方法并使用诸如Score类的操作，并相应地修改帖子。

    Facebook *_facebook;
    FacebookUser *_facebookUser;

哇，我知道这是一篇很长的文章，但是我希望有人可以帮助我指出正确的方向。

更新1：（2012/18/02）

好。 因此，我决定制作一个页面，其中包含我不想做的og元数据，并为我的对象提供了url。 根据FB文档，可在此处找到：

Open Graph Mechanics

When users take an action in your app, such as cook the Stuffed Cookie, the app calls a Graph API to create a new cook action that connects the user with the Stuffed Cookie object. This is accomplished by issuing a HTTP POST to the user’s /me/myapp:cook connection with the URL of the recipe object. Facebook will then crawl the object URL, read the metadata, and connect the object to user's Graph via the action.

The diagram below illustrates the process:

User takes an action in the app, such as "cook" a "recipe"
App calls a Graph API /me/action:object=Object_URL
Facebook will crawl the object URL, read its meta tags and connects the object to the user's Graph via the action.

如果我们可以在应用程序本身中将这些内容定义为我不需要网站的情况下的参数，那将很酷。

从2012年4月21日起，Facebook要求您创建一个页面来获取所需的数据。
