title: Is EXIF data stripped by iOS and/or Twitter on Tweets with images?
body: <p>I'm trying to tweet an image from an iOS5 app with code like this:</p>
  
  <pre><code>TWTweetComposeViewController *tweeter = [[TWTweetComposeViewController alloc] init];
  [tweeter addImage:image];
  </code></pre>
  
  <p>I think my EXIF is being stripped out, but not sure if it is my fault, the iOS Twitter code or the Twitter service.  I haven't found an authoritative answer yet, but <a href="https://dev.twitter.com/discussions/696" rel="noreferrer">How can I get geotagged pictures posted on twitter?</a> seemed to point at Twitter and <a href="http://www.digitaltrends.com/photography/twitter-photo-sharing-goes-live-for-all-users/" rel="noreferrer">Twitter photo sharing goes live for all users</a> had this in their news story:</p>
  
  <blockquote>
    <p>Photographers will be interested to learn that all EXIF data,
    information that identifies what equipment was used to take a picture
    as well as the settings used, is stripped from the photos after
    uploading</p>

  <p>I'm trying to find an official source or better authority that my code.  I also tried to Tweet a picture from the Photos app, which also seems to have lost EXIF (location) data after upload.</p>
