Cannot Put a Google Maps Gmsmapview in a Subview of Main Main View

Using the Google Maps SDK in views other than the main view

Here's how...

• add a UIView into the view controller where you're working
• set it's class to be GMSMapView in the identity inspector.

Then control-drag it to your code as you would for any other outlet.

You can lazily instantiate it in its setter...

- (void) setMapView:(GMSMapView *)mapView {
    if (!mapView) {
        mapView = [[GMSMapView alloc] initWithFrame:mapView.bounds];
    }
    _mapView = mapView;
}

To display a map Google's sample code becomes...

  GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:1.285
                                                          longitude:103.848
                                                               zoom:12];
  self.mapView = [GMSMapView mapWithFrame:CGRectZero camera:camera];

iOS Google maps sdk - markers are not pointed while using subview instead of main view

Re-Initializing the map was causing the issue. Once it is removed it solved the issue. But Re-initializing GMSMapView is causing the issue ? Its an absurd thing, but it solved the issue.

CLLocationCoordinate2D position = CLLocationCoordinate2DMake(
                                                             12.778376,
                                                             -122.409853);
currentLocation = [[CLLocation alloc] initWithLatitude:position.latitude longitude:position.longitude];
GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:eventLocation.coordinate.latitude
                                                        longitude:eventLocation.coordinate.longitude
                                                             zoom:13];
//[self.gmapsView removeFromSuperview];//removing the subview
//self.gmapsView = [GMSMapView mapWithFrame:self.gmapsView.frame camera:camera];
//self.gmapsView.delegate = self;

//self.gmapsView = self.gmapsView; //set map

// [self.view addSubview:self.gmapsView];//Adding back did the magic
self.gmapsView.delegate = self; //set delegate
self.gmapsView.camera = camera; //set camera

GMSMarker *marker = [GMSMarker markerWithPosition:position]; //Adding Marker
marker.map = self.gmapsView;
[self.gmapsView animateToLocation:currentLocation.coordinate];

Unable to recognize gestures on a subview in a GMSMapView

Put the following code:

mapView.settings.consumesGesturesInView = false

From the Google Maps iOS SDK Reference:

Controls whether gestures by users are completely consumed by the
GMSMapView when gestures are enabled (default YES). This prevents
these gestures from being received by parent views.

When the GMSMapView is contained by a UIScrollView (or other
scrollable area), this means that gestures on the map will not be
additional consumed as scroll gestures. However, disabling this (set
to NO) may be useful to support complex view hierarchies or
requirements.

Google Maps SDK not displaying properly in UIView?

Finally figured it out...

removed:

self.googleMapView = mapView;

replaced:

[self.googleMapView addSubview:mapView];

Google Maps GMSMapView on custom UIView

If you want to add a mapView after the loading of the view, then you need to create an object of GMSMapView. So break the outlets of your mapView since it will be created dynamically.

import UIKit
import GoogleMaps

class MapViewController: UIViewController {

    //Take a Google Map Object. Don't make outlet from Storyboard, Break the outlet of GMSMapView if you made an outlet
    var mapView:GMSMapView?

    override func viewDidLoad() {

        super.viewDidLoad()

        mapView = GMSMapView.map(withFrame: CGRect(x: 100, y: 100, width: 200, height: 200), camera: GMSCameraPosition.camera(withLatitude: 51.050657, longitude: 10.649514, zoom: 5.5))

        //so the mapView is of width 200, height 200 and its center is same as center of the self.view
        mapView?.center = self.view.center

        self.view.addSubview(mapView!)

    }
}

Here is the output. mapView is of width = 200 and height = 200 with center as same as self.view

Unable to navigate Google Map to location

I found solution by change outlet type GMSMapView and setting camera in viewDidLoad method.

in .h file

@property (weak, nonatomic) IBOutlet GMSMapView *mapView;

in viewDidLoad

GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:-33.86  longitude:131.20   zoom:6];
self.mapView.camera = camera;

Adding a marker to a GMSMapView subview ios

Your code is getting the map from self.views[0], then creating a new map, then adding a marker to that new map. Then you do nothing with the new map, so it won't be displayed. Nothing has been added to the original map, and so you don't see the marker.

I think you need something like this:

var tempMapSubView = self.views[0] as! GMSMapView

var position = CLLocationCoordinate2DMake(37.7833, -122.4167)

var marker = GMSMarker()
marker.position = position
marker.map = tempMapSubView
