CLRegionState UnKnown When I'm in the Region

I am testing iBeacon, I used the method didDetermineState:, and CLRegionState- CLRegionStateUnknownwhen I am inside the region, can someone tell me why?

My Bluetooth is turned on and detects beacons when I have their range for CLBeaconStateUnknown, the sender and receiver are in the range (1 Meter), here is my implementation

-(void)locationManager:(CLLocationManager *)manager didDetermineState:(CLRegionState)state forRegion:(CLRegion *)region
{

    switch (state) {
    case CLRegionStateInside:
        currentBeconRegion = (CLBeaconRegion *)region;
        [self.locationManager startRangingBeaconsInRegion:currentBeconRegion];
        NSLog(@"INSIDE the Region");//not logging
        break;
    case CLRegionStateOutside:
        NSLog(@"OUTSIDE the Region");
        break;
    case CLRegionStateUnknown:
    default:
        NSLog(@"Region state UNKNOWN!!!"); //Logging on console
        statusLabel.text = @"Region state UNKNOWN!!!";
    //[self.locationManager stopRangingBeaconsInRegion:beaconRegion];           
    [self.locationManager startRangingBeaconsInRegion:beaconRegion];//Suceessfully ranging the beacon

        break;
    }
}

I restarted both my devices and reinstalled the application, still encountering the same problem, and also did not shoot didEnterRegion:and didExitRegion:.

- (void)viewDidLoad
 {

 [super viewDidLoad];    
//set peripheralManager delegate
self.peripheralManager = [[CBPeripheralManager alloc] initWithDelegate:self
                                                                 queue:nil
                                                               options:nil];


//Set location managaer delegate
self.locationManager = [[CLLocationManager alloc] init];
self.locationManager.delegate = self;


uuid = [[NSUUID alloc] initWithUUIDString:@"E01D235B-A5DB-4717-8D2F-28D5B48931F1"];

// Setup a new region with that UUID and same identifier as the broadcasting beacon
self.beaconRegion = [[CLBeaconRegion alloc] initWithProximityUUID:uuid identifier:@"testRegion"];
self.beaconRegion.notifyEntryStateOnDisplay = YES;
self.beaconRegion.notifyOnEntry = YES;
self.beaconRegion.notifyOnExit = YES;

}

I had the same problem before and the answer was: I just forgot to call:

[self.locationManager startMonitoringForRegion:beaconRegion];

At first, I mistakenly suggested that if you start to hesitate:

[self.locationManager startRangingBeaconsInRegion:beaconRegion];

... and getting data for rssi, accuracy and UUID in the method locationManager:didRangeBeacons:inRegion:, CLLocationManager should be able to find out that the phone is in this region, but apparently not. Therefore, when querying the state using:

[self.locationManager requestStateForRegion:beaconRegion];

I got CLRegionStateUnknownfor this area in locationManager:didDetermineState:forRegion:, like you.
