EDITING GEOFENCES
For a circular geofence it’s possible to change its center and radius using center and radius properites respectively.
To modify a polygonal geofence use coordinates property.
To update a geofence when its corresponding editable NMGeoObject is modified (for example, when a user drags a NMGeoCircle to a different location), use NMGeoObjectListener onGeoObjectChanged: method:

- (void)onGeoObjectChanged:(NSUInteger)geoObjectID {
NMGeoObject *geoObject = [self geoObjectForId:geoObjectID fromArray:geoObjects];
NMGeofence *geofence = [self geoGeofenceForGeoObject:geoObject fromArray:geofences];
if ([geoObject isKindOfClass:[NMGeoCircle class]] && [geofence isKindOfClass:[NMGeofenceCircular class]]) {
NMGeoCircle *circle = (NMGeoCircle *)geoObject;
NMGeofenceCircular *geofenceCircular = (NMGeofenceCircular *)geofence;
geofenceCircular.radius = circle.radius;
geofenceCircular.center = circle.center;
} else if ([geoObject isKindOfClass:[NMGeoPolygon class]] && [geofence isKindOfClass:[NMGeofencePolygonal class]]) {
NMGeoPolygon *polygon = (NMGeoPolygon *)geoObject;
NMGeofencePolygonal *geofencePolygonal = (NMGeofencePolygonal *)geofence;
geofencePolygonal.coordinates = [polygon.vertices copy];
}
