title: How to hide default labels on Google Maps iOS SDK
body: <p>I am using <code>GoogleMapSDK v1.8</code> on my latest iOS app.
  Is it possible to display a normal  map (<code>kGMSTypeNormal</code>) without any of the default labels? </p>
  
  <p>For example, hiding some or all of the following: <strong>city labels, road labels, public transport icons, etc</strong>.
  I hope there is a way to do this.
  Please guide me the correct way to achieve my objective.</p>
