How to write an authorization page for an ios application?

Question

Objective-C

There is an application, you need to write a page on which user registration will take place, as well as a separate tab for logging in, and in addition to logging in with a username and password, you need support for logging in through social network accounts. Where can I find instructions on how to implement such an idea? Access to the main application is not available until authorization...
