问题描述
您知道，使用
[[MPMoviePlayerController alloc] initWithContentURL: aURL];
现在，我想实现一个自定义NSURLProtocol，在该协议中，我将解密已由AlgorithmDES加密的电影源.那有可能吗?感谢您提出任何想法.需要您的帮助〜
now ,i want to achieve a custom NSURLProtocol in which i will decrypt a movie source that had be encrypt by AlgorithmDES.Is that possibility? thanks for giving any ideas.need you help~
推荐答案
更新:我曾与Apple谈过此事，目前无法将MPMoviePlayerController与NSURLProtocol子类一起使用！
UPDATE: I spoke to Apple about this and it's not possible to use MPMoviePlayerController with a NSURLProtocol subclass at the moment!
嘿，
我不确定，但是有可能.我目前正在研究类似的东西，但还没有完全发挥作用.我发现MPMoviePlayerController与我的自定义NSURLProtocol子类进行交互，但是考虑NSURLRequest的HTTPHeaders似乎很重要，因为它们定义了MPMoviePlayerController需要的字节范围.
I am not sure but it could be possible. I am currently working on something similar but haven't got it fully working. What I have found out is that MPMoviePlayerController interacts with my custom NSURLProtocol subclass BUT it seems to be important to take the HTTPHeaders of the NSURLRequest into account because they define a range of bytes the MPMoviePlayerController needs.
如果将它们转储到您的NSURLProtocol子类中，您将获得两次类似的内容:
If you dump them in your NSURLProtocol subclass you will get something like this twice for the start:
2011-01-16 17:00:47.287 iPhoneApp[1177:5f03] Start loading from request: {
Range = "bytes=0-1";
}
所以我的主意是，只要您可以提供正确的范围并返回MPMoviePlayerController可以播放的mp4文件，就应该有可能！
So my GUESS is that as long as you can provide the correct range and return a mp4 file that can be played by the MPMoviePlayerController it should be possible!
