Answer 1

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 !
