title: iOS offline map for whole country (OSM)
body: <p>I tried to prepare the OSM ( *.osm.pbf ) - data of whole Italy for using it offline for an iPhone-app. I need zoom-levels from 7 to 16 because there are a lot of POI all over the country.   </p>
  
  <p><a href="https://gist.github.com/jamiely/3584016">This</a> was my starting point. The problem with this solution is the huge file-size of the database. </p>
  
  <p>Is there a open-source solution for vector-based offline map usage for iOS 6/7 ? 
  Or, is it possible to minimize the database file size? </p>
