Info about how to connect to Facebook, Twitter, etc.?

I’m looking to this but I can’t find anything related on connecting with Facebook and others, I’ve read people saying that we need to do this with C++ and such but it sounds like you need to guess all that without any info about it.

So, any of you guys got this on your app??
