title: Can I have a timer running during iOS 4.0+ multi-tasking?
body: <p>So I have just managed to build a timer on my iOS app I'm working on, and it works great! Except for the fact that the whole point of the timer is to be able to multi-task with it.</p>
  
  <p>Meaning, I want to be able to be in my app, set a timer, hit go, have it start ticking down to 0, and allow users to switch over to another app, and do that app until the timer hits 0, at which point a local notification will fire and alert them that time is up.</p>
  
  <p>Currently I have the timer and the notifications bit figured out, but when I double tap the home button to multi-task away, the timer stops, and then when I return to it, it picks back up where it left off, as if I had never left...which defeats the purpose of the timer!!</p>
  
  <p>Is it possible to have a timer run in the background with iOS 4.0?</p>
  
  <p>Thanks</p>
