how to obtain facebook credentials in iphone app when using face.com API

I am trying to make a sample iPhone app that can use the faces.recognize API call. 开发者_如何转开发 I can successfully connect to the Face.com API using RestKit, however, I have no idea how to obtain the user id, session, etc.

How can this be done?

I think reading the documentation properly would have helped more. I found a related in just 5 minutes of research at Face.com . There are a list of methods there and the realted sample responses. What you need is, I think, this URL:

http://developers.face.com/docs/api/account-users/

Getting the userID, session, etc. is actually a part of the Facebook API (not face.com) and some info about it can be found here: http://developers.facebook.com/docs/guides/mobile/
