title: Instagram API: Get User's Info (on iOS)
body: <p>My app is able to get the AccessToken after the user logs into Instagram, and Instagram calls back to my app. </p>
  
  <p>I now want to get the user's information, most importantly his/her username.</p>
  
  <p>All I have is the access token. I couldn't find a call that gives the current user's information without passing the {user-id} to it. For Example:</p>
  
  <pre><code>https://api.instagram.com/v1/users/{user-id}/?access_token=ACCESS-TOKEN
  </code></pre>
  
  <p>How do you get this information with just the AccessToken (like Twitter, Facebook, Tumblr, etc.)?</p>
