title: Draw path in MKMapView using Google Map
body: <p>I implement MKMapView in my application to draw a path between two place,i found all lat long between two point using google map API but it shows the path through road.
  My problem is that i want to show the path in building,</p>
  
  <p>For example:
  I want to draw path between the gate1 to gate 2 of Building, i pass the "to and from" lat-long in to the google MAP API, it shows the path through road so it shows the wrong distance. </p>
  
  <p>I tried the indoor map also but it works only in register buildings.</p>
