title: What does “TopicDisallowed” error reason in APNS?
body: <p>Explained in Apple's Development APNS Document:</p>
  <blockquote>
  <p>TopicDisallowed is 'Pushing to this topic is not allowed.'</p>
  <p>'The topic is currently the bundle identifier of the target application on an iOS device.'</p>
  <p>So TopicDisallowed means bundle identifier disable?</p>
  <p>Our App is off the shelf in the Apple Store，but we can use old apns protocol to push。</p>
