swift - 我怎样才能使这个 imagePickerController 能够接受编辑过的图像？

Question

如何让这个 imagePickerController 能够接受编辑后的图像？

选择图像并调整图像(缩放进出)并选择完成时，图像会恢复为原始状态。我可以在我的代码中添加什么来保存缩放图像并将其显示在我的 ImageView 中？

到目前为止，以下是我的代码:

let cameraRollAction = UIAlertAction(title: "Camera Roll", style: .default) { (action) in
    if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.photoLibrary) {
        let picker = UIImagePickerController()
        picker.delegate = self
        picker.allowsEditing = true
        picker.mediaTypes = [kUTTypeImage as String]
        picker.sourceType = UIImagePickerControllerSourceType.photoLibrary
        self.present(picker, animated: true, completion: nil)
        self.newPic = false
    }

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
    let mediaType = info[UIImagePickerControllerMediaType] as! NSString
    if mediaType.isEqual(to: kUTTypeImage as String) {
        let selectedImage = info[UIImagePickerControllerOriginalImage] as! UIImage
        profileImageView.image = selectedImage
        if newPic == true {
            UIImageWriteToSavedPhotosAlbum(selectedImage, self, #selector(imageError), nil)
        }
    }
    self.dismiss(animated: true, completion: nil)
}
