title: How to add gif to attachment in iPhone mail?
body: <p>I add .jpg this way:</p>
  
  <pre><code>UIImage *sentPic = self.image;
  NSData *imageData = UIImageJPEGRepresentation(sentPic, 1);
  [picker addAttachmentData:imageData mimeType:@"image/jpg" fileName:@"pic.jpg"];
  </code></pre>
  
  <p>I change it to "image/gif".But it doesn't work fine. Th Gif is just a still image in the mail.</p>
