title: Drawing polyline in realtime
body: <p>I'm fairly new to ios and I would like to know what would be the best approach to draw polyline on google map while user is on the move. So it would only show the path the user has traveled. I'm thinking about using current location as the destination and redraw the polyline as user moves. </p>
  
  <p>EDIT : I'm not even sure if google map is the way to go for this particular scenario since this app is free and there will be fee for API call over 2500 times/day. Is it better to go with Apple Map?</p>
