title: Any solutions for offline OpenStreetMaps with routing?
body: <p>Currently, we are trying to develop app with offline maps and routing (navigation). OpenStreetMaps looks promising (at least as an offline maps), however I'm unable to find any related routing API or SDK for it. I know, OpenStreetMaps can be used as tile images OR as vector data. But can this vector data be used for route calculation? Is there any SDK already developed with shortest and fastest route calculation? IMHO route calculation from raw data can be very time-consuming task and might be considered as separate project.</p>
  
  <p>I also started to look for alternatives and found <a href="http://googlegeodevelopers.blogspot.com/2012/12/a-new-way-to-add-google-maps-to-your.html" rel="nofollow">Google native iOS map app</a>, however, still searching is there offline map and routing support. Any ideas and experience on that will be appreciated. </p>
