How to implement Login with FaceBook in iOS app

Question

I want to implement an app which uses FaceBook login to enter the app. How can I do this. I have seen few guidelines like this https://developers.facebook.com/docs/howtos/login-with-facebook-using-ios-sdk/

I want to support iOS 3.0 and above. But really confused how to implement this. Can some one point some useful tutorials ?

Thanks

Answer 1

What you are looking for is called SSO (single sign on) for Facebook. You can use Facebook code as a starting point.

You would have a serious difficulties supporting iOS 3.x because Apple doesn't support it anymore, With the new xCode you can submit apps from 4.3 and above so consider if you want to waste your precious time debugging on something irrelevant in most cases.
