当检测到信标时，iBeacon Swift需要'requestWhenInUseAuth'吗？

Question

我尝试找到信标，因此requestAlways总是第一次获得locationPermission，但是我更改为requestWhenInUseAuth，它找不到信标。 requestAlwaysAuth

locationManager = CLLocationManager.init()
        locationManager.delegate = self
        locationManager.requestWhenInUseAuthorization()

func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) {

        if status == .authorizedWhenInUse {
            monitorBeacons()
        }

    }

func locationManager(_ manager: CLLocationManager, didRangeBeacons beacons: [CLBeacon], in region: CLBeaconRegion) {

        if beacons.count > 0 {

            majorArray.removeAll()

            for beacon in beacons {
                //                print("uuid: \(beacon.proximityUUID.uuidString) major: \(beacon.major) minor: \(beacon.minor)")

                let major = "\(beacon.major)"
                let num = (major as NSString).integerValue

                if !majorArray.contains(num){
                    majorArray.append(num)

                }

            }

        }else{



        }

    }

始终认证可以扫描信标吗？

要监控信标，您必须请求并获取获取.authorizedAlways。如果不这样做，将不会获得didEnter或didExit回调。您只能使用.authorizedWhenInUse来进行 range 信标，但是显示的代码永远不会开始进行测距，而只是监视。
