title: Ask for iOS 8 device APNS token twice
body: <p>So I already have called </p>
  
  <pre><code>[[UIApplication sharedApplication]registerForRemoteNotifications] 
  </code></pre>
  
  <p>and successfully got apns token through </p>
  
  <pre><code>didRegisterForRemoteNotificationsWithDeviceToken
  </code></pre>
  
  <p>delegate method but I did nothing with it and iOS do not allow me to ask user for push notification access again.</p>
  
  <p>How can I get device APNS token after user already accepted to receive notification?</p>
