Sharing on social media

I am creating a small ios app in which i want to share some links on Social media platforms like Twitter, Gmail, Phone message, Facebook.

I dont want to just open app/website, It should open it with passed url in Post page so that i can just click Post/Send to send message.

Can anyone guide me to do it in Twitter/Gmail/Whatsapp/Facebook/Phone Message ?
Do we have any xojo library for this ?
