I am working on beacon detecting in foreground, background and kill (remove from background) app.I have kontakt beacon.I have implemented location Manager delegate method but I can’t detect beacon in foreground and background not even called method didEnterRegion and didExitRegion .For solution I merge location manager delegate with KTKDevicesManagerDelegate. I can’t detect beacon in location manager so I have tried implementing in didRangeBeacons of location manager method I start devicesManager.startDevicesDiscovery() of KTKDeviceManagerDelegate that time detect beacon in Foreground and background ,but I can’t detect beacon when we kill app. I have already added in Info.plist NSBluetoothPeripheralUsageDescription , NSLocationAlwaysUsageDescription , NSLocationWhenInUseUsageDescription , bluetooth-central , fetch , location.
I have added following on didFinishLaunchingWithOptions requestAlwaysAuthorization(),requestWhenInUseAuthorization().
//MARK:- Variable initializers
var devicesManager: KTKDevicesManager!
var locationManager = CLLocationManager()
let region = CLBeaconRegion(proximityUUID: NSUUID(uuidString: "********")! as UUID, identifier: "detected")
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
Kontakt.setAPIKey(“*******************”)
self.locationManager.delegate = self
devicesManager = KTKDevicesManager(delegate: self)
//When bluetooth Is on that time
devicesManager.startDevicesDiscovery(withInterval: 3)
}
//MARK: - KTKDevicesManagerDelegate Method
extension AppDelegate: KTKDevicesManagerDelegate {
func devicesManager(_ manager: KTKDevicesManager, didDiscover devices: [KTKNearbyDevice]) {
for device in nearbyDevices {
if let uniqueID = device.uniqueID {
print("Detected a beacon \(uniqueID)")
} else {
print("Detected a beacon with an unknown unique ID")
devicesManager.stopDevicesDiscovery()
}
}
}
func devicesManagerDidFail(toStartDiscovery manager: KTKDevicesManager, withError error: Error?) {
print("Discovery did fail with error: \(error)")
devicesManager.stopDevicesDiscovery()
}
}
//MARK: - Location Manager Method
extension AppDelegate: CLLocationManagerDelegate {
private func locationManager(manager: CLLocationManager!, didChangeAuthorizationStatus status: CLAuthorizationStatus) {
print("STATUS CHANGED: \(status.rawValue)")
if status == .authorizedAlways {
print("YAY! Authorized!")
locationManager.startMonitoring(for: region)
}
}
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
print("update location")
locationManager.startMonitoring(for: region)
locationManager.startRangingBeacons(in: region)
}
func locationManager(_ manager: CLLocationManager, didStartMonitoringFor region: CLRegion) {
print("The monitored regions are: \(manager.monitoredRegions)")
locationManager.startMonitoring(for: region)
locationManager.startRangingBeacons(in: region as! CLBeaconRegion)
}
func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {
print("Location Manager failed with the following error: \(error)")
}
func locationManager(_ manager: CLLocationManager, didRangeBeacons beacons: [CLBeacon], in region: CLBeaconRegion) {
// print("beacons : \(beacons.count)")
devicesManager.startDevicesDiscovery()
//So called didDiscover method of KTKDevicesManagerDelegate method
}
func locationManager(_ manager: CLLocationManager, monitoringDidFailFor region: CLRegion?, withError error: Error) {
print("FAIL!")
}
