The core component of Navmii SDK responsible for geofencing is NMGeofenceManager. This class provides an API for managing user geofences and transition event notifications.
CREATING GEOFENCE MANAGER
NMSdk class contains a property geofenceManager which allows Navmii SDK user to access geofence manager instance. The geofence manager instance can only be accessed if the SDK is started.
GEOFENCE TYPES
The geofence manager supports two types of geofence geometry:
NMGeofenceCircular
NMGeofencePolygonal
GEOFENCE EVENTS
The geofence manager provides a NMGeofenceListener interface to handle transition events:
- (void)onGeofenceEnter:(nonnull NSString *)geofenceId geofenceTag:(nullable NSString *)geofenceTag;
- (void)onGeofenceExit:(nonnull NSString *)geofenceId geofenceTag:(nullable NSString *)geofenceTag;
You can add listeners using addGeofenceListener method:
[sdk.geofenceManager addGeofenceListener:geofenceListener];
Don't forget to detach listeners using removeGeofenceListener method:
[sdk.geofenceManager removeGeofenceListener:geofenceListener];
