title: Push Notification on iOS
body: <p>I'm pretty new to iOS development, and was just wondering is it possible to activate your iOS application with a Push Notification.</p>
  
  <p>On Android it is possible to use services for background work, but with iOS, unfortunately you can't, I know some things work, like VoIP, but that would be rejected by Apple, as far as I know, but what I mean is could I make my iOS application do just a little bit of work for like 30 seconds or so, every so often, via Push Notifications?</p>
  
  <p>PS: I know Push Notification is for advanced users, but I want to know if the above is possible otherwise I will have to scrap my idea =[</p>
  
  <p>Thanks.</p>
