使用Core Bluetooth处理iBecon信号我能够使用CBCentralManager扫描选项搜索nil: –
- Shared.sharedInstance.centralManager?.scanForPeripherals(withServices: nil,options:[CBCentralManagerScanOptionAllowDuplicatesKey:true])
但是,当我提供我理想的服务ID,即: –
- Shared.sharedInstance.centralManager?.scanForPeripherals(withServices: [serviceID],options:[CBCentralManagerScanOptionAllowDuplicatesKey:true])
它从不调用didDiscoverPeripheral Delegate方法,我也需要在后台模式下扫描外设,并且根据Apple文档,您需要在需要在后台模式下扫描时明确提供服务ID.任何人都可以帮助我在这里做错事.
解决方法
我这样用,
连接按钮单击事件
并使用CBCentralManagerDelegate,CBPeripheralDelegate Delegate
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)
- }
- }
