Answer 1

请检查如下：

- (void)viewDidLoad   
{
  [super viewDidLoad];
  if ([self.mapView isKindOfClass:[GMSMapView class]]) {
    self.mapView.myLocationEnabled = YES;

    self.mapView.mapType = kGMSTypeNormal;

    self.mapView.settings.compassButton = YES;

    self.mapView.settings.myLocationButton = YES;

    self.mapView.delegate = self;
  }else
  {
    NSLog(@"Make sure your object is GMSMapView because its not!!");
  }  
}
