Google Maps iOS SDK "mapView:didTapMarker:" crashes - ios

Question

I have a subclass of GMSMarker called customMarker.
My user gets notifications every time he approaches one of the markers on the map.
I want that when the user clicks on a notification, the marker will be already selected (when the app opens from the notification) adn its infoWindow will be visible.
I try to do it like this:
-(void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification
{
AroundersViewController *aroundersVC=[[UIStoryboard storyboardWithName:#"Main" bundle:nil] instantiateViewControllerWithIdentifier:#"aroundersPage"];
NSString *markerIdentifier=[[notification userInfo] objectForKey:#"markerIdentifier"];
CustomMarker *notificationsMarker=[self.monitorLocationVC markerForIdentifier:markerIdentifier];
[aroundersVC mapView:aroundersVC.mapView didTapMarker: notificationsMarker]; //App crashes here
}
But the app crashes with this error log message:
2016-02-11 20:39:30.355 App[15887:4216691] -[AroundersViewController mapView:didTapMarker:]: unrecognized selector sent to instance 0x7fa01bcf5890
