title: GMSMapViewDelegate Methods Not Being Called?
body: <p>I am using the Google Maps iOS API. None of the delegate methods are firing. How do I make them work?</p>
  
  <p>MapViewController.h:</p>
  
  <pre><code>@interface MapViewController : UIViewController &lt;GMSMapViewDelegate&gt;
  @property (strong, nonatomic) IBOutlet GMSMapView *mapView_;
  
  @end
  
  #import "MapViewController.h"
  #import &lt;GoogleMaps/GoogleMaps.h&gt;
  @interface MapViewController ()
  
  @end
  </code></pre>

      @synthesize mapView_;
