title: Change GMSMapView default map background color in iOS
body: <p>The GMSMapView in iOS has a default background color of tan, or something like it. </p>
  
  <p>I have a requirement to change that color to white. I've tried using a subclass of GMSTileLayer without success (or errors). I need to place custom map overlays with white backgrounds onto the map view. In areas without the overlays, the base map color needs to match (white).</p>
  
  <p>Tried the following without any luck:</p>
  
  <pre><code>[mapView setBackgroundColor:[UIColor whiteColor]];
  </code></pre>
  
  <p>Can anyone offer suggestions, or point me to a resource (other than Google) that might help? </p>
  
  <p>Thanks!</p>
