推荐答案

如果您想使用UIImagePicker保存视频，可以通过以下方式轻松将它们保存到相册：

If you want to save videos with a UIImagePicker, you can easily save them to the Photos Album via:

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info; {
  NSURL * movieURL = [[info valueForKey:UIImagePickerControllerMediaURL] retain];// Get the URL of where the movie is stored.
  UISaveVideoAtPathToSavedPhotosAlbum([movieURL path], nil, nil, nil);
}

这允许您将其保存到相册，并保留参考路径电影后来使用。我不太确定这是否是你需要的，但它确实可以让你保存电影。

This allows you to save it to the Photos Album, and keep a reference path to the movie for use later. I'm not quite sure if this is what you need, but it does allow you to save movies.

编辑：如果你真的想要要将电影保存到文档目录，只需使用上面的代码，然后更改行：

If you really want to save the Movie to documents directory, simply take the above code, and change the line:

UISaveVideoAtPathToSavedPhotosAlbum([movieURL path], nil, nil, nil);

到

NSData * movieData = [NSData dataWithContentsOfURL:movieURL];

这将为您提供电影的数据，并从那里，您可以将该数据写入文件目录。希望有所帮助！

This will give you the data of the movie, and from there, you can write that data to the documents directory. Hope that helps!
