title: Undefined symbols for architecture armv7 while using Google-Maps-iOS-SDK (1.8.1)
body: <p>I am trying to add <strong>Google-Maps-iOS-SDK (1.8.1) using cocoapods (0.33.1)</strong>.</p>
  
  <p>Deployment target version: <strong>iOS 7.0</strong></p>
  
  <p>I have added this pod: <code>pod 'Google-Maps-iOS-SDK'</code>, '~> 1.8'
  Downloaded and installed sdk properly.</p>
  
  <p>I started adding header file and sample map view loading code from <a href="https://developers.google.com/maps/documentation/ios/start" rel="noreferrer">here</a>.</p>
  
  <p>I have properly added API keys. In one view controller's <code>- (void)viewDidLoad</code>,<br>
  I have added following code:</p>
  
  <pre><code> // Create a GMSCameraPosition that tells the map to display the
  // coordinate -33.86,151.20 at zoom level 6.
  GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:-33.86
                                                          longitude:151.20
                                                               zoom:6];
  GMSMapView *mapView_ = [GMSMapView mapWithFrame:CGRectZero camera:camera];
  mapView_.myLocationEnabled = YES;
  self.view = mapView_;
  
  // Creates a marker in the center of the map.
  GMSMarker *marker = [[GMSMarker alloc] init];
  marker.position = CLLocationCoordinate2DMake(-33.86, 151.20);
  marker.title = @"Sydney";
  marker.snippet = @"Australia";
  marker.map = mapView_; 
  </code></pre>
  
  <p>I got this error on build for iPhone (not in simulator)</p>

  <p>I also tried using google map iOS sdk manual installation (without cocoapods). I have also added linker flag: <code>-ObjC</code>. It builds fine but crash on runtime showing selector not found error like this:</p>
  
  <p>an NSException is thrown with the description -
  -[GMSMapView animateToCameraPosition:]: unrecognized selector sent to instance.</p>
  
  <p>I just need to use google map iOS SDK either using cocoapod or from manual installation. </p>
  
  <p>Am I missing anything here? </p>
  
  <p><strong>Edit</strong></p>
  
  <p>If there is anything related with Pods.xcconfig then here is the content of that file:  </p>
