I have written an async call to download a video of mp4 format. The response result is an NSData. How can I open the NSData in any video player framework which should be supported in IOS 3.

推荐答案

NSData本质上是一个容器对象，因此不是您可以在视频播放器中播放的格式.无需查看任何代码或数据结果，您就可以使用

An NSData is basically a container object, and thus not in a format you can play in a video player. Without seeing any code, or the results of your data, you can create an NSString from data with

NSString *dataString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];

现在您有了一个字符串，您可以使用以下方式创建一个NSURL

Now that you have a string, you can create an NSURL with

NSURL *movieURL = [NSURL URLWithString:dataString];

从那里，您应该能够使用

From there, you should be able to pass this into an MPMoviePlayerController with

MPMoviePlayerController *moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:movieURL];
