title: How to show a Info window in iOS Google maps without tapping on Marker?
body: <p>I am new to iOS development. This is regarding Marker info window in Google Maps iOS SDK.</p>
  
  <p>I understand, we can create a marker with info window using GMSMarkerOption.</p>
  
  <pre><code>GMSMarkerOption *myLocationOption = [GMSMarkerOption alloc];
  myLocationOption .title = @"My Location";
  myLocationOption .snippet = @"Lat:...., Lang:....";
  
  [mapView addMarkerOption:myLocationOption];
  </code></pre>
  
  <p>As per the above code, Marker displayed in the Map View as expected. 
  And tapping on marker shows the "My Location" info window in Google maps which is good.</p>
  
  <p>Is there anyway we can show the info window programmatically when the user goes to Custom Map Screen?</p>
