title: Make api call every hour after app is terminated in IOS
body: <p>I am creating a new ios app and it needs to call web api and update badge number every hour after user manually kill the app or it's in background.
  I have searched long time but couldn't find any great solution.</p>
  
  <p>I do not want to use push notification. Scalability is too huge for every device because I need to do it every hour.</p>
