我在 swift 4 中的 imagePickerViewController 出现错误

Question

为 ImagepickerViewController 调用委托方法时出现此错误

Error Domain=PlugInKit Code=13 "query cancelled" UserInfo={NSLocalizedDescription=query cancelled}

我的委托方法是

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any])
{

    if let image = info[UIImagePickerControllerOriginalImage] as? UIImage
    {
         UserDefaults.standard.set(UIImagePNGRepresentation(image), forKey: "avatarImage")
    }
    else
    {
        //Error message
    }
    self.dismiss(animated: true, completion: nil)
}

编辑：我尝试了其他问题的答案，但它们没有用
