title: iOS - CoreLocation and geofencing while app is closed
body: <p>I've read many tutorials about geofencing my iOS app (i.e., <a href="http://mobile.tutsplus.com/tutorials/iphone/geofencing-with-core-location/">here</a>), but none mention whether or not iOS allows any app-specific location data to be handled when the app is closed. </p>
  
  <p>For instance, I understand that when the app is in the background, these services will still persist (if coded correctly), but how about when the user double taps the home button and closes the app? Can location data still be obtained?</p>
