title: iOS Run Code Once a Day
body: <p>The idea behind this app is very simple: download a file. However this app will be for people who are not always within internet access range, so I need it to know that at, say 9:00 AM, to download a file to the hard drive. There will be a button within the app to do it manually as well, but I've already got that working.</p>
  
  <p>As I understand it, this will be difficult if it is even possible. I know that iOS doesn't like multitasking, but I am also aware that it does allow for background timer functions. I am open to any sort of suggestions anyone might have to accomplish this, even if it means writing a separate app. Thanks.</p>
  
  <p>Edit: I see there is the possibility of working with Notifications, or even maybe the Calendar. Ideas in that category as also welcomed.</p>
  
  <p>Edit 2: I also read something about an external server initiating an app, but it gave no description.</p>
