使用 facebook connect 为 iPhone 上传照片的记录过程 [英] Documented process for using facebook connect for the iPhone to upload photos
问题描述
看了之后,我确实在 facebook 论坛上看到了这篇文章:
After looking I did come accross this post on the facebook forums:
他们正在向 facebook 对象提供 UIImage.这似乎合乎逻辑,但这是在哪里记录的?API 文档适用于所有平台.iPhone 对参数及其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****我仍然没有遇到任何与 Cocoa 相关的 API 文档.不过,我确实通过拼凑论坛信息、Facebook 示例代码和一些胶水来收集我需要的信息.
******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.
希望他们能在接下来的几个月内发布更具体的内容.
Hopefully they'll issue something a little more concrete over the next few months.

接下来是我对 SessionViewController 的实现:
What follows is my implementation of a SessionViewController:
