Swift 3将视频上传到带有标题的Facebook

Question

以下代码用于将视频上传到Facebook。但是，我如何提供与视频相关的文字/标题/评论。提前谢谢。

func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject]) {

    let video : FBSDKShareVideo = FBSDKShareVideo()
    video.videoURL = info[UIImagePickerControllerMediaURL] as! NSURL
    let content : FBSDKShareVideoContent = FBSDKShareVideoContent()
    content.video = video

}
