title: iPhone MapKit Framework to cache Google map for offline use
body: <p>I am planning on a map project for hiking on iPhone.</p>
  
  <p>Since the area for hiking may not be covered by mobile network. Therefore, it is necessary to pre-cache the map (Google) of the area.</p>
  
  <p>1) Can MapKit Framework support caching Google Map on iPhone locally ?
  2) Can MapKit Framework support to use offline map during GPS-ing ?</p>
  
  <p>Thanks.</p>
