Question

我的应用程序在前台和后台运行时可以正常运行信标监控，即使我退出应用程序它在后台启动应用程序..但是当我重新启动手机时它不会被唤醒..

//我也在使用背景模式进行定位

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

    //do i have to do anything here

    return true
}

//当应用程序命中背景波纹管方法将触发并且我正在开始区域监控

func applicationDidEnterBackground(_ application: UIApplication) {


    do {
        try DLGatewayInterface.getInstance().enableBackgroundWakeups()
        try DLGatewayInterface.getInstance().startBackgroundScan(start: true)
    } catch let error {
        print(error)
    }


}

//当应用程序启动区域监控时，这将触发我设置委托

var gatewayBridgeDelegate: DLGatewayBridgeDelegate?
private var locationManager:CLLocationManager
private var Region:CLBeaconRegion
var savedDevices = UserDefaults.standard
var major = ""
var minor = ""

override init() {


    locationManager = CLLocationManager()


    super.init()

    locationManager.delegate = self

    // required as "ALWAYS" for iBeacon
    locationManager.requestAlwaysAuthorization()

}

//每当app遇到背景时都会触发

public func startRegionMonitoring()
{

    if let beaconName = UserDefaults.standard.value(forKey: "beaconDeviceRegion") as? String{
        print(beaconName)

        self.decimalToHexForMajorMinor(value: beaconName)

        danlawRegion = CLBeaconRegion(
            proximityUUID: BeaconServiceId,
            major: CLBeaconMajorValue(DLUtils.beaconMajor),
            minor: CLBeaconMinorValue(DLUtils.beaconMinor),
            identifier: "Danlaw")
                // reset the regions...just in case
          stopRegionMonitoring()
        // only add it if you need to
        if(!locationManager.monitoredRegions.contains(Region)) {
            locationManager.startMonitoring(for: Region)
        }
    }

}


public func stopRegionMonitoring(){
    danLogDebug()
    locationManager.stopMonitoring(for: danlawRegion)
    resetRegions() // clear all regions...
}




 extension DLLocationManager: CLLocationManagerDelegate {
public func locationManager(_ manager: CLLocationManager, 
didChangeAuthorization status: CLAuthorizationStatus) {
    if status == .authorizedAlways || status == .authorizedWhenInUse {

    }
}

public func locationManager(_ manager: CLLocationManager, 
didFailWithError error: Error) {
    danLogWarn(error.localizedDescription)
}

public func locationManager(_ manager: CLLocationManager, 
didUpdateLocations locations: [CLLocation]) {

}

public func locationManager(_ manager: CLLocationManager, 
didEnterRegion region: CLRegion) {
    // in this bellow method i am calling scanning again
    onRegionEnter(region: region.identifier)

}

public func locationManager(_ manager: CLLocationManager, didExitRegion region: CLRegion) {

    onRegionExit(region: region.identifier)

}

public func locationManager(_ manager: CLLocationManager, monitoringDidFailFor region: CLRegion?, withError error: Error) {

}
public func locationManager(_ manager: CLLocationManager, didDetermineState state: CLRegionState, for region: CLRegion) {


    onRegionDetermineState(region: region.identifier, state: state.rawValue)
}
public func locationManager(_ manager: CLLocationManager, didStartMonitoringFor region: CLRegion) {

    onRegionMonitorStart(region: region.identifier)
}

}

您必须设置信标监控并在didFinishLaunching中设置CoreLocation委托。如果不这样做，您将无法获得自动启动行为。

var locationManager: CLLocationManager?  

func application(_ application: UIApplication,  didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
  locationManager = CLLocationManager()
  locationManager?.delegate = self
  let region = CLBeaconRegion(proximityUUID: Uuid, identifier: "my_region")
  locationManager?.startMonitoring(for: region)
}

当我重新启动设备时，我的IOS应用程序没有得到任何区域更新？
