How put Google MapView in UIView?

问题:

I'm trying to put Google MapView in UIView but I get nothing displayed.

My code,

*.h

#import <UIKit/UIKit.h>
#import <GoogleMaps/GoogleMaps.h>

@interface ViewController : UIViewController

@property (weak, nonatomic) IBOutlet UIBarButtonItem *btnLocate;
@property (weak, nonatomic) IBOutlet GMSMapView *mapView_;
@property (weak, nonatomic) IBOutlet UIView *mapView;

@end

*.m

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

Thanks.

Solution

GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:-33.86
                                                            longitude:151.20
                                                                 zoom:6];

    // Indicating the map frame bounds
    self.mapView_ = [GMSMapView mapWithFrame:self.mapView.bounds camera: camera]; 
    self.mapView_.myLocationEnabled = YES;

    // Add as subview the mapview
    [self.mapView addSubview: self.mapView_]; 

So, i got the solution. Thanks anyway.

Best regards.

Essentially in the storyboard, for the corresponding View(UIVIew) you're going to show the Google Map, you have to set the class as GMSMapView in identity inspector.

This is how view controller would look like in Swift 3.

class GMapsViewController: UIViewController {
    @IBOutlet weak var mapContainerView: GMSMapView!

    override func viewDidLoad() {
        super.viewDidLoad()

        let camera = GMSCameraPosition.camera(withLatitude: -33.86, longitude: 151.20, zoom: 6.0)

       let marker = GMSMarker()
       marker.position = CLLocationCoordinate2D(latitude: -33.86, longitude: 151.20)
       marker.title = "Sydney"
       marker.map = mapContainerView

       mapContainerView.moveCamera(GMSCameraUpdate.setCamera(camera))


       }
}
