推荐答案

您需要通过通用HTTP连接机制自行请求数据，例如 NSURLConnection 。如果 NSHTTPURLResponse 的标题通过了您的测试，那么您应该将其保存到 NSCachesDirectory 并将URL传递给这个资源到 AVPlayer 就像这样：

You'll need to request the data yourself via a generic HTTP connection mechanism such as NSURLConnection. If the NSHTTPURLResponse's headers pass your test, then you should save it into the NSCachesDirectory and pass off the URL to this resource to the AVPlayer like so:

NSData *data = //your downloaded data.
NSString *filePath = //generate random path under NSCachesDirectory
[data writeToFile:filePath atomically:YES];

AVPlayer *player = [AVPlayer playerWithURL:[NSURL fileURLWithPath:filePath]];
//...
