iBeacon major and minor value inside didEnterRegion

Question

I'm trying to access the major and minor values for the closest beacon within the didEnterRegion delegate. However, when printing the values to the console they return null

- (void)locationManager:(CLLocationManager *)manager didEnterRegion:(CLRegion *)region {

    if ([region isKindOfClass:[CLBeaconRegion class]]) {

        CLBeaconRegion *beaconRegion = (CLBeaconRegion *)region;

        int major = [beaconRegion.major intValue];
        int minor = [beaconRegion.minor intValue];

        NSLog(@" Major %@ Minor %@", beaconRegion.major, beaconRegion.minor);

        }
}

Answer 1

The region monitoring callback you have implemented will not tell you the individual identifiers of the beacons you detect. If you want to get the identifiers for individual beacons detected, you have to use the beacon ranging APIs as @Larme says in his comment. The callback for ranging includes a second parameter that is an array of all beacons seen.
