title: Find polygon of City or region on Map
body: <p>I want to draw a border around the city or the area user has searched on the map. I am using Google Place API to find Lattitude and Longitude of Location. But I also want boundary of City or area. So I can draw a polygon around that area to show.</p>
  
  <p>For Example, If User search "New York, USA", I want to draw overlay covering only New York City on map. </p>
  
  <p>Is there any API which I can use in ios to find the whole region on the map? </p>
