swift - iBeacon swift 在检测 Beacon 时需要 'requestWhenInUseAuth'？

Question

我尝试找到信标，所以总是第一次请求获取 locationPermission，但我更改为 requestWhenInUseAuth，它找不到信标。 请求始终验证

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{



        }

    }

alwaysAuth应该可以扫描beacon吗？

为了监控信标，您必须请求并获得 .authorizedAlways。如果你不这样做，你将不会得到 didEnter 或 didExit 回调。您可以仅使用 .authorizedWhenInUserange 信标，但显示的代码永远不会开始测距，仅进行监控。
