title: Black screen when assigning google maps to subview
body: <p>I am trying to load places inside Google Map View for iOS6.
  How to set the frame for the Map ?
  Currently it is fullscreen</p>
  
  <pre><code> -(void)loadView {
  
     GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:10.00989
                                                          longitude:76.316142
                                                               zoom:15];
     mapView_ = [GMSMapView mapWithFrame:CGRectZero camera:camera];
     self.view = mapView_;
  
     }
  </code></pre>
  
  <p>I tried by creating a new (small) view inside the current view and add map inside that,but at that time the page is not getting loaded.It shows a full black screen</p>
  
  <pre><code> -(void)loadView {
  
    GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:10.00989
                                                          longitude:76.316142
                                                               zoom:15];
     mapView_ = [GMSMapView mapWithFrame:CGRectZero camera:camera];
  
     [self.view Addsubview:newView];
     self.newView = mapView_;
  
     }
  </code></pre>
