title: Google API OVER_QUERY_LIMIT issue in iOS
body: <p>I have typical issue. </p>
  
  <ol>
  <li>I am hitting Place search API and Getting Results.</li>
  <li>After that i need Show the Driving Distance for each of the Place to display.</li>
  <li>To do so i am hitting Google API 10 times to fetch 10 Driving distance.</li>
  <li><p>But as google does not allow multiple hit within a seconds, So google is returning OVER_QUERY_LIMIT after 1 or 2 response.</p>
