iphone - MPMoviePlayerViewController 虽然通过了身份验证，但无法播放视频

Question

尝试使用 MPMoviePlayerViewController 观看视频时出现此错误。视频网址在 Safari 浏览器上运行良好，但在 iPhone/iPad 上却不行。

NSConcreteNotification 0x122b9ab0 {name = MPMoviePlayerPlaybackDidFinishNotification; object = <MPMoviePlayerController: 0x12243330>; userInfo = {
    MPMoviePlayerPlaybackDidFinishReasonUserInfoKey = 1;
    error = "Error Domain=MediaPlayerErrorDomain Code=-11829 \"Cannot Open\" UserInfo=0x122bc190 {NSLocalizedDescription=Cannot Open}";

使用 Charles 代理，我可以看到那里的请求：

Status  Complete
Response Code   401 Unauthorized
Protocol    HTTP/1.1
Method  GET
Content-Type    text/html

然后

Status  Complete
Response Code   206 Partial Content
Protocol    HTTP/1.1
Method  GET
Content-Type    video/mp4

然后

Status  Complete
Failure Client closed connection before receiving entire response
Response Code   206 Partial Content

Method  GET
Content-Type    video/mp4

同样的问题在这里iOS：播放需要身份验证的视频在 QuickLook 中有效，但在 MPMoviePlayerViewController 中无效
