I have three brand new Kontakt.io beacons and used this tutorial and its source to try and identify them with my iPhone 4s. All I did is change the UUID (all Kontakt.io beacons had the same UUID fromt the start) and add some code:
This line is supposed to force the app to check also if it's already IN the region
[self.locationManager requestStateForRegion:self.myBeaconRegion];
These lines are supposed to check if the system is set up in the correct way:
NSArray *locationServicesAuthStatuses = @[@"Not determined",@"Restricted",@"Denied",@"Authorized"];
NSArray *backgroundRefreshAuthStatuses = @[@"Restricted",@"Denied",@"Available"];
BOOL monitoringAvailable = [CLLocationManager isMonitoringAvailableForClass:[self.myBeaconRegion class]];
NSLog(@"Monitoring available: %@", [NSNumber numberWithBool:monitoringAvailable]);
int lsAuth = (int)[CLLocationManager authorizationStatus];
NSLog(@"Location services authorization status: %@", [locationServicesAuthStatuses objectAtIndex:lsAuth]);
int brAuth = (int)[[UIApplication sharedApplication] backgroundRefreshStatus];
NSLog(@"Background refresh authorization status: %@", [backgroundRefreshAuthStatuses objectAtIndex:brAuth]);
When I start the app, with the iBeacons next to my phone, didEnterRegion is not fired. Also when I take out the battery and put them back in (to simulate going out of the range and going back in), nothing happens. Other Github-example codes didn't work for me either when using real iBeacons, only when I use another iPhone to transmit the signals.
This is the ViewController.h:
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
// Initialize location manager and set ourselves as the delegate
self.locationManager = [[CLLocationManager alloc] init];
self.locationManager.delegate = self;
// Create a NSUUID with the same UUID as the broadcasting beacon
NSUUID *uuid = [[NSUUID alloc] initWithUUIDString:@"A77A1B68-49A7-4DBF-914C-760D07FBB87B"];
// Setup a new region with that UUID and same identifier as the broadcasting beacon
self.myBeaconRegion = [[CLBeaconRegion alloc] initWithProximityUUID:uuid
identifier:@"com.appcoda.testregion"];
// Tell location manager to start monitoring for the beacon region
[self.locationManager startMonitoringForRegion:self.myBeaconRegion];
// Force app to check if it's already IN the region
[self.locationManager requestStateForRegion:self.myBeaconRegion];
// Check if beacon monitoring is available for this device
if (![CLLocationManager isMonitoringAvailableForClass:[CLBeaconRegion class]]) {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Monitoring not available" message:nil delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles: nil]; [alert show]; return;
}
NSArray *locationServicesAuthStatuses = @[@"Not determined",@"Restricted",@"Denied",@"Authorized"];
NSArray *backgroundRefreshAuthStatuses = @[@"Restricted",@"Denied",@"Available"];
BOOL monitoringAvailable = [CLLocationManager isMonitoringAvailableForClass:[self.myBeaconRegion class]];
NSLog(@"Monitoring available: %@", [NSNumber numberWithBool:monitoringAvailable]);
int lsAuth = (int)[CLLocationManager authorizationStatus];
NSLog(@"Location services authorization status: %@", [locationServicesAuthStatuses objectAtIndex:lsAuth]);
int brAuth = (int)[[UIApplication sharedApplication] backgroundRefreshStatus];
NSLog(@"Background refresh authorization status: %@", [backgroundRefreshAuthStatuses objectAtIndex:brAuth]);
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (void)locationManager:(CLLocationManager*)manager didEnterRegion:(CLRegion *)region
{
// We entered a region, now start looking for our target beacons!
self.statusLabel.text = @"Finding beacons.";
[self.locationManager startRangingBeaconsInRegion:self.myBeaconRegion];
}
-(void)locationManager:(CLLocationManager*)manager didExitRegion:(CLRegion *)region
{
// Exited the region
self.statusLabel.text = @"None found.";
[self.locationManager stopRangingBeaconsInRegion:self.myBeaconRegion];
}
-(void)locationManager:(CLLocationManager*)manager
didRangeBeacons:(NSArray*)beacons
inRegion:(CLBeaconRegion*)region
{
// Beacon found!
self.statusLabel.text = @"Beacon found!";
CLBeacon *foundBeacon = [beacons firstObject];
// You can retrieve the beacon data from its properties
//NSString *uuid = foundBeacon.proximityUUID.UUIDString;
//NSString *major = [NSString stringWithFormat:@"%@", foundBeacon.major];
//NSString *minor = [NSString stringWithFormat:@"%@", foundBeacon.minor];
}
This is the NSLog output:
2014-05-29 00:49:19.951 BeaconReceiver[2803:60b] Monitoring available: 1
2014-05-29 00:49:19.967 BeaconReceiver[2803:60b] Location services authorization status: Authorized
2014-05-29 00:49:20.109 BeaconReceiver[2803:60b] Background refresh authorization status: Available
Thanks a lot for your help!!
