ios – 无法通过CBCentral Manager扫描iBecon信号的服务ID

Shared.sharedInstance.centralManager?.scanForPeripherals(withServices: nil,options:[CBCentralManagerScanOptionAllowDuplicatesKey:true])

Shared.sharedInstance.centralManager?.scanForPeripherals(withServices: [serviceID],options:[CBCentralManagerScanOptionAllowDuplicatesKey:true])

我这样用,
连接按钮单击事件
并使用CBCentralManagerDelegate,CBPeripheralDelegate Delegate

func connectDevice(sender:UIButton){


                if peripheral != nil {
                    manager.cancelPeripheralConnection(peripheral)
                    manager = CBCentralManager(delegate: self,queue: nil)
                }
        }



 func centralManagerDidUpdateState(central: CBCentralManager) {
        if central.state == CBCentralManagerState.PoweredOn {
            central.scanForPeripheralsWithServices(nil,options: nil)
        } else {
            self.showAlert(Messages().alert,message: "Bluetooth is not on.")
        }
    }



 func centralManager(central: CBCentralManager,didDiscoverPeripheral peripheral: CBPeripheral,advertisementData: [String : AnyObject],RSSI: NSNumber) {
        let device = (advertisementData as NSDictionary).objectForKey(CBAdvertisementDataLocalNameKey) as? NSString
        print(device)

        if device?.containsString(BEAN_NAME) == true {
            self.manager.stopScan()
            self.peripheral = peripheral
            self.peripheral.delegate = self
            manager.connectPeripheral(peripheral,options: nil)
        }
    }
