title: UIActivityViewController - preserve file name of attached files from read from URL
body: <p>Is there an equivalent code to this (code below) for iOS6 UIActivityViewController? The question is, can I share data via url and preserve the file name? As of now the only way I can figure out how to do it is to convert the PDF to NSData and add the data as an activityItem. Works fine, but I lose the name of the attached pdf.</p>
  
  <pre><code>[composer addAttachmentData:pdfData mimeType:@"application/pdf" fileName:@"myPDF.pdf"];
  </code></pre>
