Cannot put a google maps GMSMapView in a subview of main main view?

Question

I\'m struggling with this problem! I want to add a google maps GMSMapView into a UIView that is only a portion of the main UIView of m

Answer 1

Following the google tutorial for Swift in Sep-2017

I fixed by putting the code in viewDidLoad like this

var mapView: GMSMapView!

override func viewDidLoad() {
    super.viewDidLoad()

    // Create a GMSCameraPosition to display the initial center of the map
    let camera = GMSCameraPosition.camera(withLatitude: 23.885942, longitude: 45.079162, zoom: 5.1)

    // Set the frame size , don't forget to replace "<CustomFrame>" with the required frame size
    mapView = GMSMapView.map(withFrame: "<CustomFrame>", camera: camera)

    // Add the map to any view here 
    view.addSubview(mapView)  //or customView.addSubview(mapView)
}

Answer 2

I was getting the black screen just because i forgot to add this line:

[super loadView];

Answer 3

(void)viewDidLoad {
    GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:-33.86
                                                        longitude:151.20
                                                             zoom:14];

    GMSMarker *marker = [[GMSMarker alloc] init];
    marker.position = CLLocationCoordinate2DMake(-33.86, 151.20);
    marker.title = @"Sydney";
    marker.snippet = @"Australia";
    marker.map = self.mapContainerView;

    //set the camera for the map
    self.mapContainerView.camera = camera;

    self.mapContainerView.myLocationEnabled = YES;
}

My suggestions:

1. Link the UIView from your storyboard to your header file as a UIView instance variable, not a GMSMapView
2. Change the mapWithFrame:camera: method to be set to your linked UIView's bounds
3. At the end of the viewDidLoad: method, set the UIView instance variable to your GMSMapView, or add a subview. I've had trouble with this as well, and fooling around with this usually will work.

.h

@interface MapViewController: UIViewController <CLLocationManagerDelegate>
{
    IBOutlet UIView *mapViewOnSreen;
}

.m

- (void)viewDidLoad
{
    [super viewDidLoad];

    // Do any additional setup after loading the view.
    GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:-33.8683
                                                                longitude:151.2086
                                                                     zoom:10];
    _mapView = [GMSMapView mapWithFrame:mapViewOnScreen.bounds camera:camera];
    _mapView.myLocationEnabled = YES;

    mapViewOnScreen = _mapView
    //OR [self.view addSubview:_mapView];
    //OR [mapViewOnScreen addSubview:_mapView];   <--This worked for me
}

*Edit: I created a small UIView inside the main view using IB. I followed the steps listed and I was able to view the map inside the small UIView when I set [mapViewOnScreen addSubview:_mapView];

Answer 5

you can do it through IB

.h
@property (weak, nonatomic) IBOutlet GMSMapView *theMapView;

.m
GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:-33.868
                                                        longitude:151.2086
                                                             zoom:12];

//This next line is not needed if you have a GMSMapView outlet
//self.theMapView = [GMSMapView mapWithFrame:self.theMapView.frame camera:camera];
self.theMapView.camera=camera;
self.theMapView.mapType = kGMSTypeSatellite;
self.theMapView.delegate=self;

set the UIVIEW class to be GMSMapView in the identity inspector.

then make an IBOutlet from it :D and hola it is work :P
