How to post a photo on social media networks?

Question

React Native

I'm building a React Native postcard app for a uCoz website.
I'm interested to know how to implement sending a postcard in .gif format via instant messengers installed on the phone? Maybe there is some kind of SDK, library?
If you can, then help, otherwise the whole Internet has been covered - not a damn useful thing.

Answer 1

Through the phone - is it through the standard sharing window? Then through the standard element UIActivityViewController . Search the internet for anything related to it.
