安卓外围设备与IOS交互代码

安卓外围设备与iOS设备交互的代码需要使用跨平台的技术，例如蓝牙、Wi-Fi、NFC等。以下是一个使用蓝牙进行安卓外围设备与iOS设备交互的示例代码：

安卓设备代码：

BluetoothAdapter bluetoothAdapter = BluetoothAdapter.getDefaultAdapter();

// 扫描周边设备并连接
bluetoothAdapter.startDiscovery();
BluetoothDevice device = null;
for(BluetoothDevice d : bluetoothAdapter.getBondedDevices()) {
    if(d.getName().equals("iOS设备名称")) {
        device = d;
        break;
    }
}
if(device == null) {
    // 没有找到iOS设备
    return;
}
BluetoothSocket socket = device.createRfcommSocketToServiceRecord(UUID.fromString("00001101-0000-1000-8000-00805F9B34FB"));
socket.connect();

// 发送数据
OutputStream outputStream = socket.getOutputStream();
outputStream.write("Hello iOS!".getBytes());
outputStream.flush();

iOS设备代码：

import CoreBluetooth

let peripheralName = "安卓设备名称"

var centralManager: CBCentralManager!
var peripheral: CBPeripheral!

// 初始化蓝牙管理器并扫描周边设备
centralManager = CBCentralManager(delegate: self, queue: nil)
centralManager.scanForPeripherals(withServices: nil, options: nil)

// 实现CBCentralManagerDelegate协议
extension ViewController: CBCentralManagerDelegate {
    func centralManagerDidUpdateState(_ central: CBCentralManager) {
        if central.state == .poweredOn {
            centralManager.scanForPeripherals(withServices: nil, options: nil)
        }
    }
    
    func centralManager(_ central: CBCentralManager, didDiscover peripheral: CBPeripheral, advertisementData: [String : Any], rssi RSSI: NSNumber) {
        if peripheral.name == peripheralName {
            self.peripheral = peripheral
            centralManager.connect(peripheral, options: nil)
        }
    }
    
    func centralManager(_ central: CBCentralManager, didConnect peripheral: CBPeripheral) {
        peripheral.delegate = self
        peripheral.discoverServices(nil)
    }
}

// 实现CBPeripheralDelegate协议
extension ViewController: CBPeripheralDelegate {
    func peripheral(_ peripheral: CBPeripheral, didDiscoverServices error: Error?) {
        if let services = peripheral.services {
            for service in services {
                peripheral.discoverCharacteristics(nil, for: service)
            }
        }
    }
    
    func peripheral(_ peripheral: CBPeripheral, didDiscoverCharacteristicsFor service: CBService, error: Error?) {
        if let characteristics = service.characteristics {
            for characteristic in characteristics {
                if characteristic.properties.contains(.writeWithoutResponse) {
                    peripheral.writeValue("Hello Android!".data(using: .utf8)!, for: characteristic, type: .withoutResponse)
                }
            }
        }
    }
}

以上代码仅供参考，具体实现还需要根据具体需求进行调整。
