Question

我正在研究在前景，背景中执行信标检测并杀死（从后台删除）应用程序。我有kontakt信标。我已经实现了位置管理器委托方法，但无法在前景和背景中检测信标。甚至称为方法didEnterRegion和didExitRegion。对于解决方案，我将位置管理器委托与KTKDevicesManagerDelegate合并。我无法在位置管理器中检测到信标，因此我尝试在位置管理器方法的didRangeBeacons中实现，我启动了KTKDeviceManagerDelegate的devicesManager.startDevicesDiscovery()，该时间可在前景和背景中检测信标，但是当我们杀死应用程序时，我无法检测到信标。我已经在Info.plist中添加了NSBluetoothPeripheralUsageDescription，NSLocationAlwaysUsageDescription，NSLocationWhenInUseUsageDescription，bluetooth-central，fetch，location。我在didFinishLaunchingWithOptions requestAlwaysAuthorization(),requestWhenInUseAuthorization()上添加了以下内容。

    //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!")
    }

    func locationManager(_ manager: CLLocationManager, didEnterRegion region: CLRegion) {
        print("Region Entered")

        locationManager.startMonitoring(for: region)
        locationManager.startRangingBeacons(in: region as! CLBeaconRegion)

    }


    func locationManager(_ manager: CLLocationManager, didExitRegion region: CLRegion) {
        print("Region exited")

        locationManager.startMonitoring(for: region)
        locationManager.startRangingBeacons(in: region as! CLBeaconRegion)

    }

}

Answer 1

您必须在NSLocationAlwaysUsageDescription中添加并允许位置。如果您在执行该时间didEnterRegion方法的信标区域中并且在执行该时间didExitRegion方法的信标区域之外，则我们开始并停止设备发现。我们可以检测到前台，后台，手机锁定以及应用程序处于杀死状态的信标。

按如下所示修改您的方法。

    func locationManager(_ manager: CLLocationManager, didEnterRegion region: CLRegion) {
            print("Region Entered")
            devicesManager.startDevicesDiscovery()


        }


        func locationManager(_ manager: CLLocationManager, didExitRegion region: CLRegion) {
            print("Region exited")
            devicesManager.stopDevicesDiscovery()    
        }
