ViewController not showing on Google Map didTapMarker method - iOS

Question

I have a DetailViewController that is to be shown when user taps a marker on the mapView_. Initially I load the VC and set it hidden, and when the user would tap a marker, I would load values in the VC and show it. But it is not happening. Here's my code.

@property (strong, nonatomic) GMSMapView *mapView;

- (void)viewDidLoad 
{
    [super viewDidLoad];

    _whisperDetailView.hidden = YES;

    [_whisperDetailView initlize];
    _whisperDetailView.viewController = self;

    GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:-33.86
                                                            longitude:151.20
                                                                 zoom:6];
    mapView_ = [GMSMapView mapWithFrame:CGRectZero camera:camera];
    mapView_.myLocationEnabled = YES;
    self.view = mapView_;
}



- (BOOL)mapView:(GMSMapView *)mapView didTapMarker:(GMSMarker *)marker
{

    _detailView.whisper = marker.userData;
    _detailView.hidden = NO;

    return YES;
}

Storyboard snapshot:

Funny thing is I was using Mapbox before and was doing exact same thing in its didSelectAnnotation function and everything was working great. I recently had to switch to Google Map and now its not working.

Any help is appreciated. Thanks.

Okay I've got it working now! Posting the answer for anyone else stuck in same situation:

I changed the way I was adding my mapView_. instead of assigning self.view = mapView in viewDidLoad, I inserted mapView as a subview to my main view, like this:

mapView_ = [GMSMapView mapWithFrame:CGRectMake(0, 0, self.view.bounds.size.width, self.view.bounds.size.height) camera:camera];
[self.view insertSubview:mapView_ atIndex:0];

And alas! everything works like a charm now! When I tap a marker, my DetailViewController shows with proper sizes and as I set it up in storyboard.
