print("file attacher")
let file = UIImagePickerController()
file.delegate = self
file.sourceType = UIImagePickerControllerSourceType.photoLibrary
file.mediaTypes = ["public.image", "public.movie"]

推荐答案
您不能限制显示的内容或阻止用户选择更大的视频.用户选择后,您可以查看该文件并决定不对其进行任何操作.
You cannot limit what’s displayed or prevent the user from choosing a bigger video. After the user chooses, you can look at the file and decide to do nothing with it.
