FBConnect iOS SDK publish_action問題

Question

我必須說我現在感覺像個白癡。 :)我一直在Facebook，谷歌和StackOverflow上下，仍然無法得到我做錯了什麼的答案！ :)我看了兩個Facebook示例：Hackbook和WishList。 Wishlist顯然是應該告訴我該怎麼做的人，但是全部我見過的例子有OBJECT部分作爲URL。我不一定希望這樣，因爲我只想讓帖子說（此用戶）正在玩[MyGame]。

好的，這是我的目標。我有一款iPhone遊戲。我想要做什麼，當你聽一首歌，時間軸和股票的帖子。我也想用它來將玩家的得分發布在用戶的時間軸和代碼中。

我使用名爲Play的動作和名爲Game的對象及其聚集器來設置Open Graph。我想我也需要一個叫做Score的動作？

無論如何，我可以使用feed對話框成功發佈到用戶的牆上，但這不是我想要的Play操作。

這裏是什麼，我走到這一步，一個簡潔的版本，任何的幫助深表感謝：

夫婦注： 我有一個單身FacebookInfo這需要處理Facebook的代表和東西照顧。我也有一個FacebookUser類，它保存當前用戶的當前會話信息，當調用me時填充。我也有一個DLog方法，它只在調試模式下執行NSlog。

當用戶點擊我遊戲中的Play按鈕時，我想在下面調用我的方法[[Facebook sharedInfo] publishAction:@"play"]。我通過NSString作爲動作，因此稍後我可以調用相同的方法並使用類似Score的動作，並相應地修改該帖子。

哇，我知道這是一個很長的帖子，但我希望有人能幫點我朝着正確的方向。

UPDATE 1：（2012/18/02）

好的。所以我決定做一個包含我不想做的og元數據的頁面，併爲我的對象提供url。按照該FB文檔，發現here：

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.

這將是冷靜，如果我們可以定義的應用程序本身這些東西作爲params用於在那裏，我不需要一個網站的情況。

截至4/21/12 Facebook要求您創建一個頁面以獲取所需的數據。
