title: ios background fetch app settings - read from info.plist in code
body: <p>In my iOS App I've enable the Backgrdound Fetch capability available since iOS 7 (Project > Capablities > Background Modes > Background Fetch).</p>
  
  <p>Initially, I defined a boolean setting (I called it "<em>Enable Background Fetch</em>") in <code>Root.plist</code> allowing the app to enable/disable this functionality but, after recompiling and executing, I've noticed that in the app settings screen, a boolean setting named "<em>Background App Refresh</em>" is already added automatically on top of my other custom settings.</p>
  
  <p>My question is: can I access the value of this automatically added property, and not have to define my own duplicate setting key? I need to read the value of the property from my app code, since other aspects of my app's behaviour depend on whether background fetches are enabled or not.</p>
  
  <p>Can I invoke <code>NSUserDefaults.standardUserDefaults().boolForKey(...)</code> and in this case which value for the key should I use?</p>
