title: Can iPhone apps start on start-up?
body: <p>I've answered <a href="https://stackoverflow.com/q/8523072/840973">two</a> different <a href="https://stackoverflow.com/q/6690435/840973">questions</a> now, both explaining how VOIP apps <strong>don't</strong> start on start-up, yet people seem to think they do.</p>
  
  <p>I'm not 100% sure myself, someone linked me to a <a href="https://developer.apple.com/library/ios/#documentation/iPhone/Conceptual/iPhoneOSProgrammingGuide/AdvancedAppTricks/AdvancedAppTricks.html#//apple_ref/doc/uid/TP40007072-CH7-SW14" rel="nofollow noreferrer">part of the apple docs</a>, which doesn't really mention anything about auto-starting of apps.</p>
  
  <p>I was originally going on prior knowledge and <a href="https://stackoverflow.com/a/6690577/840973">this answer</a>, but after another person saying that they do, I'm really not sure. </p>
  
  <p>As far as I'm aware, apps only react to push notifications, and can't be launched into the background when a device is turned on.</p>
  
  <p>Can we please clarify whether it is possible to auto-start an app or not?</p>
