title: Fetch friends birthday using facebook graph api v2.0
body: <p>In v1.0, it was possible to ask for permissions that would allow an app to see a limited amount of friend data, such as a person's friend's likes, their birthdays, and so on.</p>
  
  <p>In v2.0, those permissions have all been removed. It's no longer possible for an app to see data from a person's friends unless those friends have also logged into the app and granted permission for the app to see it that data.</p>
  
  <p>Now the issue is that how we can get the friends birthday.I am using  user_friends permission that is providing me list of friends with their id, first name,middle name,gender but not birth day.</p>
