In Backbone.js platform, I can login with a social network and pass an optional parameter ('create: false') telling Kinvey to do not create a new user if no user with the provided social identity exists.



Thanks.

My question is, How can I do this on login method on iOS?

Fabrício, what are you looking to have happen?

I just can't find HOW can I do login with facebook, using this method



loginWithSocialIdentity:accessDictionary:withCompletionBlock:



and DO NOT create a new user on kinvey if that facebook profile is not linked with an account on kinvey.



I mean, login with facebook never create an account, it is just a shortcut for an existing user for doing login.

I see now, this currently not supported with the iOS KinveyKit.

If you created a username abc@kinvey.com with password, then a user is created in the user collection. Then if you log out and use Facebook, whose email is also abc@kinvey.com, to log in (with Facebook), you actually created another user whose username is also abc@kinvey.com. This is a violation of unique username. Then many errors will follow....
