记录使用Facebook连接iPhone进行上传照片的过程 [英] Documented process for using facebook connect for the iPhone to upload photos
问题描述
看完后，我在Facebook论坛上发贴了这篇文章：
After looking I did come accross this post on the facebook forums:
他们正在向facebook对象提供UIImage。这似乎是合乎逻辑的，但这里记录在哪里？ API文档通用于所有平台。 iPhone的参数和数据类型的具体要求在哪里？
They are feeding the facebook object a UIImage. That seems logical, but where is this documented? The API documentation is generalized to all platforms. Where are the iPhone specific requirements for arguments and their data types?
谢谢
******更新*****
我还没有遇到任何有关Cocoa的API文档。然而，我已经收集了我所需要的信息，将论坛信息，Facebook示例代码和一些胶水拼凑在一起。
******Update***** I still have not came across any API docs pertaining to Cocoa. I did, however, gather the information I needed by piecing together forum information, Facebook sample code, and some glue.
希望他们会发布一些更具体的东西未来几个月。
Hopefully they'll issue something a little more concrete over the next few months.

接下来是我的实现的一个SessionViewController：
What follows is my implementation of a SessionViewController:
