iPhone: Social media integration

I am developing iPhone app where I need to provide integration with different social media like FaceBook, Twitter, Google etc. I have seen couple of iPhone applications that allow people to login using their existing FB or Twitter accounts and allow to post comments, like/unl开发者_如何学编程ike, follow people etc. I want to implement something similar but not sure where to start with. Could anyone please suggest me right direction? Any documentation and sample code would be great help.

Thanks.

http://developers.facebook.com/ has just about all the info you might need. Further also look in Apples library as it contains sample code and extensive information about most topics.

@AppleDeveloper, check out Socialize; this is exactly the problem we're working to solve: http://www.GetSocialize.com. Full feature list at http://go.GetSocialize.com/features

The problem with just putting Facebook into your app is that your download base of users aren't all friends on Facebook. So any sharing in the app using Facebook will only go out to that user's friends.

Socialize lets all users of the app see the social actions other users of the app take, in addition to allowing those social actions to be shared on Facebook (and soon Twitter & Google+ as well). Then we give you a reporting dashboard so you can see the effect of all the social actions on downloads & user engagement: http://go.GetSocialize.com/dashboard

Let me know if this is the type of thing you're looking for.
