title: Why Was This App Rejected?
body: <p>Apple rejected this app, and even provided a long explanation in the Resolution Center, but I am not certain why.  Could someone help me translate?</p>
  
  <blockquote>
    <p>2.23</p>
    
    <p>We found that your app does not follow the iOS Data Storage
    Guidelines, which is required per the App Store Review Guidelines.</p>
    
    <p>In particular, we found that on launch and/or content download, your
    app stores downloaded media (MP3 files). To check how much data your
    app is storing:</p>
    
    <ul>
    <li>Install and launch your app</li>
    <li>Go to Settings > iCloud > Storage &amp; Backup > Manage Storage</li>
    <li>If necessary, tap "Show all apps"</li>
    <li>Check your app's storage</li>
    </ul>
    
    <p>The iOS Data Storage Guidelines indicate that only content that the
    user creates using your app, e.g., documents, new files, edits, etc.,
    may be stored in the /Documents directory - and backed up by iCloud.</p>
    
    <p>Temporary files used by your app should only be stored in the /tmp
    directory; please remember to delete the files stored in this location
    when the user exits the app.</p>
    
    <p>Data that can be recreated but must persist for proper functioning of
    your app - or because customers expect it to be available for offline
    use - should be marked with the "do not back up" attribute. For NSURL
    objects, add the NSURLIsExcludedFromBackupKey attribute to prevent the
    corresponding file from being backed up. For CFURLRef objects, use the
    corresponding kCFURLIsExcludedFromBackupKey attribute.</p>
    
    <p>For more information, please see Technical Q&amp;A 1719: How do I prevent
    files from being backed up to iCloud and iTunes?.</p>
    
    <p>It is necessary to revise your app to meet the requirements of the iOS
    Data Storage Guidelines. For discrete code-level questions, you may
    wish to consult with Apple Developer Technical Support. Please be sure
    to:</p>
    
    <ul>
    <li>include the complete details of your rejection issues</li>
    <li>prepare any symbolicated crash logs, screenshots, and steps to reproduce the issues for when the DTS engineer follows up.</li>
    </ul>
    
    <p>For information on how to symbolicate and read a crash log, please see
    Tech Note TN2151 Understanding and Analyzing iPhone OS Application
    Crash Reports.</p>
    
    <p>If you have difficulty reproducing this issue, please try testing the
    workflow as described in
    <a href="https://developer.apple.com/library/ios/qa/qa1764/" rel="nofollow">https://developer.apple.com/library/ios/qa/qa1764/</a>Testing Workflow
