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:

If i tap on map then one marker pin is generate at that location now if i tap on another location on map then two pins are displayed but i want to remove the old marker pin.

I also use,

[self.mapView clear];

But it was clear all other marker points from GMSMapview.

Following is the code to add pin on Map:

            GMSMapView *mapView;
            GMSMarker *currLocMarker = [[GMSMarker alloc] init];
            currLocMarker.map  = nil;
            [currLocMarker setTitle:NSLocalizedString(@"current_location_title", nil)];
            currLocMarker.icon = [UIImage imageNamed:@"pin_fetch_location.png"];
            currLocMarker.position = CLLocationCoordinate2DMake(pCoordinate.latitude, pCoordinate.longitude);
            currLocMarker.map = self.mapView;

Please help me to solve out this stuff..!!

Thanks in advance..:)

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

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 !
