Google Maps for iOS - How can you tell if a marker is within the bounds of the screen?

Question

I\'m trying to figure out a straightforward way to determine in Google Maps for iOS if a given GMSMarker is within the bounds of the visible map. There seems to be solution

Answer 1

A code example based on Andy's helpful response:

- (void)snapToMarkerIfItIsOutsideViewport:(GMSMarker *)m{
    GMSVisibleRegion region = _mapView.projection.visibleRegion;
    GMSCoordinateBounds *bounds = [[GMSCoordinateBounds alloc] initWithRegion:region];
    if (![bounds containsCoordinate:m.position]){
        GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:m.position.latitude
                                              longitude:m.position.longitude
                                                   zoom:_mapView.camera.zoom];
        [self.mapView animateToCameraPosition: camera];
    }
}
