title: Google maps sdk - Map overlays evrything in my storyboard
body: <p>So i am using xcode 6.2 and i am starting with making apps.
  but i have a question: whenever i drag something in my storyboard like a navigation bar the map overlays it, it simply won't show up, please help.
  Here is my code</p>
  
  <pre><code>#import "ViewController.h"
  
  @interface ViewController () {
      GMSMapView *mapView;
  }
  
  @end
  
  @implementation ViewController
  
  - (void)viewDidLoad {
      [super viewDidLoad];
      GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:43.642510 longitude:-79.387038 zoom:12 bearing:0 viewingAngle:0];
      mapView = [GMSMapView mapWithFrame:CGRectZero camera:camera];
      mapView.myLocationEnabled = YES;
      self.view = mapView;
  
  
      GMSMarker *marker = [[GMSMarker alloc] init];
      marker.position = CLLocationCoordinate2DMake(43.642510, -79.387038);
      marker.title = @"CN-Tower";
      marker.snippet = @"A beautifull tower";
      marker.map = mapView;
      marker.opacity = 0.7;
  }
  </code></pre>
  
  <p>Thanks anyway,
  JP</p>
