title: iOS Instagram login get Instagram user id?
body: <p>I am writing an iOS app that needs to do some basic work against the "Instagram API". To login a user I simply hit the "<a href="https://instagram.com/oauth/authorize/?client_id=%3Cmy_client_id%3E&amp;redirect_uri=%3Credirect%20URI%3E&amp;response_type=token" rel="nofollow">URL</a>":</p>
  
  <p>I do this through a web view. I am able to login the user and get the access token from "Instagram".</p>
  
  <p>So my question is:</p>
  
  <p>I want to be able to know the "Instagram userId" of the user I just logged in.  </p>
  
  <p>How can I get the user id?</p>
