Remove particular GMSMarker from GMSMapview using Google Map sdk in ios

Question

I am integrating google maps sdk. Its all work fine. But how to remove particular Marker(Pin Point) when second will appear.(I am not using Mapkit)

I want the following:

Answer 1

To remove a particular pin from GMSMapView keep reference of pin (if there are multiple then use array) then use this code

currLocMarker.map  = nil;

To remove all things including pins poly lines from GMSMapView use this code

[ _mapView clear];

Answer 2

Yes, I got that solution. Add pin like the following:

- (void)mapView:(GMSMapView *)mapView didTapAtCoordinate:(CLLocationCoordinate2D)coordinates {

pCoordinate.latitude =coordinates.latitude;
pCoordinate.longitude =coordinates.longitude;

[[GMSGeocoder geocoder] reverseGeocodeCoordinate:CLLocationCoordinate2DMake(coordinates.latitude, coordinates.longitude) completionHandler:^(GMSReverseGeocodeResponse *resp, NSError *error)
                {
     [currLocMarker setTitle:NSLocalizedString(@"current_location_title", nil)];
     currLocMarker.icon = [UIImage imageNamed:@"pin.png"];
     currLocMarker.position = CLLocationCoordinate2DMake(coordinates.latitude,       coordinates.longitude);
     currLocMarker.map = self.mapView;} ] ;}

Please remove the following line if you used in the above:

GMSMarker *currLocMarker = [[GMSMarker alloc] init];

Answer 3

loop all marker in the map , and you can use title or snippet to decide which marker you remove

as map.markers is no longer to use in google map ios sdk , you need to have a nsmutablearray to store all marker for looping purpose

and you can make use of userData of the marker , marker.userData , which i prefer to store a nsdictionary information in the marker in order to prevent from duplicate name of title .

cheers.

Check This one and try it in your code

Answer 5

This worked for me -

func removeMarkers(mapView: GMSMapView){
    for (index, _) in markers.enumerate() {
        //print("Item \(index): \(element)")
                    self.markers[index].map = nil
    }
}

where

    var markers = [GMSMarker]()

markers contains all the marker overlays for the mapView

Answer 6

swift 5

func mapView(_ mapView: GMSMapView, didTap marker: GMSMarker) -> Bool
{
    let alertcontrolserver = UIAlertController.init(title : nil, message : "Are you sure you want to Remove ! ", preferredStyle: .alert)
        let okbtn = UIAlertAction(title: "Yes", style: .default, handler: { UIAlertAction in  marker.map = nil
             })
    let cancelbtn = UIAlertAction(title: "No", style: .default, handler: nil)
        alertcontrolserver.addAction(okbtn)
       alertcontrolserver.addAction(cancelbtn)
        self.present(alertcontrolserver, animated: true, completion: nil)
    return true
}
