我正在尝试将大文件视频文件上传到 Facebook，但无论采用何种方法，结果总是相同的。该过程会上传 5-35mb 的数据，然后超时。这发生在 WiFi 上。
我尝试过使用 Facebook SDK 3.1.1、iOS 社交库（即 SLRequest）和 AFNetworking。
社交库和 afnetworking 会出现超时错误，而 Facebook SDK 只返回代码 5，无法完成操作，HTML 错误 200，但如果我通过仪器观看网络活动，它具有相同的签名，即一定数量的在停止之前上传兆字节。
请注意，使用这三种方法中的任何一种，我都可以毫无问题地上传较小的视频。
有没有人遇到过这个问题并找到任何解决方案或原因？
ps 我相信它是一个 Facebook 错误，如果其他人想订阅它以鼓励他们调查它，我已经在那里记录了一个问题（https://developers.facebook.com/bugs/265409976924087）。
