React Native save image in iOS camera roll

Question

How to save the image in the response label on the iOS camera? has a uri source. The CameraRoll class has a method called saveImageWithTag, but it's unclear how to use it. I think the documentation is not good enough.

I have the same problem and I test my own CameraRoll API, it provides a static function

static saveImageWithTag(tag, successCallback, errorCallback)
