Our design team decided to use a custom layout for social sharing. For example, it will have 2 buttons on social networks (Telegram and Twitter for example). After deprecating a Social framework (iOS 11) is it possible to share directly to (Telegram for example)in iOS 13?
I don't want to use UIActivityViewController. I need to open specific social extensions without UIActivityViewController!
I have checked this: Social framework is deprecated in iOS11
You can only do this with applications that support custom url schemas.
Some of them have official api, like instagram, some may have a private one that you can use as well, but at your own risk: the creators can remove or change this functionality; and some have none.
But you won't be able to create a post or message like you do in the UIActivityViewController, only to pass some data that the other application will somehow handle.
