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

When you tap on specific marker this will remove that marker

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

    marker.map = nil;
    return YES;
}

Answer 2

I made like this:

GMSMarker *myMarker;

- (void)mapView:(GMSMapView *)mapView didTapAtCoordinate:(CLLocationCoordinate2D)coordinate
{
    [[NSOperationQueue mainQueue] addOperationWithBlock:^{
        if (myMarker) {
            myMarker.map = nil;
            myMarker = nil;
        }
        myMarker = [[GMSMarker alloc] init];
        myMarker.position = CLLocationCoordinate2DMake(coordinate.latitude, coordinate.longitude);
        myMarker.title = @"title";
        myMarker.map = mapView_;
    }];
}

and worked well for me !

Answer 3

In case you have different markers, and you want to remove only specific markers from the map, then you have to hold that marker(s) object.

say if you have 
var removableMarkers: [GMSMarker]?

you have to append those markers in the above array when adding markers to map

Now, when you want to remove those markers:
  _ = self.removableMarkers.map({
            $0.map = nil
        })
self.RemovableMarkers = []

That's it!
