swift获取app网络和本地网络权限

请求蓝牙权限：

 //蓝牙if #available(iOS 13.1, *) {let autostate = CBManager.authorizationif(autostate == .notDetermined){print("")self.manager = CBCentralManager(delegate: nil, queue: DispatchQueue.main,options: [CBCentralManagerOptionShowPowerAlertKey:false])
//                    manager.state}} else {let manager = CBCentralManager(delegate: nil, queue: DispatchQueue.main)let state:CBManagerAuthorization = manager.authorizationswitch(state){case .notDetermined:
//                    KdBLEService.shared().requestBleToothPermission()breakcase .restricted:breakcase .denied:breakcase .allowedAlways:break@unknown default:break}}

无线网权限：

CTCellularData().cellularDataRestrictionDidUpdateNotifier = {state inswitch state {case .restrictedStateUnknown://未知item.pstate = .unknownlet reachAbility:Reachability = Reachability.forInternetConnection()let wifiState:NetworkStatus = reachAbility.currentReachabilityStatus()switch(wifiState){case NotReachable:item.serviceState = falsebreakdefault:break}case .restricted://受限制if(item.pstate != .stricted){item.pstate = .strictedself.stateAsyncUpdate?()}item.pstate = .strictedcase .notRestricted://Reachability库文中尾部放入//不受限制print("第一次进来也会显示这个状态，第一次进来需要")let reachAbility:Reachability = Reachability.forInternetConnection()let wifiState:NetworkStatus = reachAbility.currentReachabilityStatus()switch(wifiState){case NotReachable:item.serviceState = falsebreakdefault:break}if(item.pstate != .on){item.pstate = .on}self.stateAsyncUpdate?()item.pstate = .on@unknown default:print("")}

本地网络权限：

class LocalNetworkPermissionTester {var connection: NWConnectionvar success = falsevar semaphore: DispatchSemaphoreinit(semaphore: DispatchSemaphore) {self.semaphore = semaphorelet dispatchQueue = DispatchQueue(label: "LocalNetworkPermissionTester")self.connection = NWConnection(host: "127.255.255.255", port: 9, using: .udp)self.connection.stateUpdateHandler = { state inswitch state {case .ready:self.success = truesemaphore.signal()case .waiting(_):
//                if #available(iOS 14.2, *) {
//                    print("reason: \(self.connection.currentPath?.unsatisfiedReason)")
//                    if case .localNetworkDenied? = self.connection.currentPath?.unsatisfiedReason {
//                        self.success = false
//                        semaphore.signal()

//                }default:break}}connection.start(queue: dispatchQueue) // this will trigger the prompt if necessary}
}

 public func getLocalNetPermission(item:KdPermissionItem){
//        Task.init {
//            do{
//                let isOK = try await  KdLocalNetworkManager().requestAuthorization()
