ESTBeaconManager initialization

BLE Beacons
1

I am trying to initialize the beacon manager object and start ranging beacons on a button click but the ESTBeaconManagerDelegate methods are not being called. Below shown is the code.

-(IBAction)startRangingBeacons:(id)sender
{
      self.beaconManager = [ESTBeaconManager new];
      self.beaconManager.delegate = self;
      self.beaconRegion = [[CLBeaconRegion alloc]
                             initWithProximityUUID:[[NSUUID alloc]
                                                    initWithUUIDString:@"B9407F30-F5F8-466E-AFF9-25556B57FE6D"]
                             identifier:@"ranged region"];
    [ self.beaconManager requestAlwaysAuthorization];
     [self.beaconManager startRangingBeaconsInRegion:self.beaconRegion];
}

- (void)beaconManager:(id)manager didRangeBeacons:(NSArray *)beacons
             inRegion:(CLBeaconRegion *)region
{
    DDLogInfo(@"didRange called");
}

- (void)beaconManager:(id)manager
rangingBeaconsDidFailForRegion:(CLBeaconRegion * _Nullable)region
            withError:(NSError *)error
{
    DDLogInfo(@"error in ranging --- %@",[error localizedDescription]);
}

Please help me to resolve this issue.

Did you added ESTBeaconManagerDelegate?
