title: Found empty data in sqlite when send via MFMailcomposeController
body: <p>I am sending <strong>SQLite(Coredata sqlite file)</strong> file via email but found empty data in all tables in the received mail. </p>
  
  <p>I am using below code:</p>
  
  <pre><code>MFMailComposeViewController *mc = [[MFMailComposeViewController alloc] init];
  mc.mailComposeDelegate = self;
  [mc setSubject:subject];
  [mc setMessageBody:body isHTML:FALSE];
  if (attachmentData) {
   [mc addAttachmentData:attachmentData mimeType:fileMimeType fileName:fileName];
  }
  if (!recipients || recipients.count == 0) {
   recipients = @[];
  }
  [mc setToRecipients:recipients];
  [presentedViewController presentViewController:mc animated:YES completion:nil];
  </code></pre>
  
  <blockquote>
    <p>Here, fileMimeType = "application/x-sqlite3" and fileName: xyz.sqlite</p>
  </blockquote>
  
  <p>Found the same <a href="https://stackoverflow.com/q/26833013/1635315">question</a> here, but with no solution. Any idea how to do that?</p>
