get user email from twitter framework in ios

i am using Twitter framework (iOS-5 and iOS-6 ) to get user details but i need user email id to be able to log in in my system. I have seen many post regarding this like

link1

link2

and i have also checked twitter reverse api here

but it is giving me only auth tokens.

Can someone please confirm me that we can't get user email from twitter or i am not been able to figure it out. Already i have wasted my lots of time searching for this please help.

Thanks

You certainly can't get user email from Twitter.
