使用facebook連接iPhone的上傳照片的記錄過程

Question

看完之后我在facebook論壇上發了這篇文章：

鏈接

他們正在為Facebook對象提供UIImage。 這似乎合乎邏輯，但這在哪里記錄？ API文檔推廣到所有平台。 iPhone對參數及其數據類型的具體要求在哪里？

謝謝

******更新*****我還沒有遇到任何與Cocoa有關的API文檔。 但是，我確實通過拼湊論壇信息，Facebook示例代碼和一些膠水來收集我需要的信息。

希望他們能在接下來的幾個月內發布更具體的內容。

為了完整性：

以下說明如何與Facebook Connect進行交互： https ： //developers.facebook.com/docs/guides/web/

API調用： https ： //developers.facebook.com/docs/reference/api/

如果您需要擴展權限： https ： //developers.facebook.com/docs/guides/policy/examples_and_explanations/Extended_Permissions/

Mobile Orchard上一個不錯的Obj-C包裝器： http ： //www.mobileorchard.com/marketing-in-code-part-2-setting-a-users-status-in-facebook-from-an-iphone-app-一個教程/

接下來是我對SessionViewController的實現：

照片上傳的圖Api文檔如下。

你可以在這里看到如何在iPhone中做到這一點。

Joe Hewitt（Facebook iPhone應用程序的作者）發布了Facebook應用程序的大部分作為他的Three20框架。 它托管在github上 。
