这里描述的是flutter与原生工程的通信交互
我的做法是写了个文件覆盖了methodChannel的代理方法，将收发功能封装进了一个类
SwiftFlutterBridge.swift、并将通信约定字符写在了宏定义文件里FlutterBridgeConst.swift
- 必不可少的约定字符为以下三种(根据自己的项目需要去设定)
static let MethodChannel = "com.example.flutter/method"
static let EventChannel = "com.example.flutter/event"
static let BasicMessageChannel = "com.example.flutter/basicMessage"- 在AppDelegate里注册通信
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
// 注册与Flutter的通信
SwiftFlutterBridge.shared.load(methodChannel: FlutterBridgeConst.MethodChannel, eventChannel: FlutterBridgeConst.EventChannel, messageChannel: FlutterBridgeConst.BasicMessageChannel)
self.window?.backgroundColor = .white
self.window?.rootViewController = UINavigationController(rootViewController: RootViewController())
self.window?.makeKeyAndVisible()
return true
}- 遵守协议代理及加载flutter页面 可以根据需要仅仅跳转或是直接加载
SwiftFlutterBridge.shared.delegate = self
DispatchQueue.main.async {
self.addChild(SwiftFlutterBridge.shared.flutterViewController)
self.view.addSubview(SwiftFlutterBridge.shared.flutterViewController.view)
SwiftFlutterBridge.shared.flutterViewController.view.frame = self.view.bounds
SwiftFlutterBridge.shared.flutterViewController.view.autoresizingMask = [.flexibleWidth, .flexibleHeight]
}- 原生向flutter发送信息
func sendMessageToFlutter(message: Any) {
if let messageChannel = basicMessageChannel {
messageChannel.sendMessage(message)
}
}Flutter这边的方法是使用工厂模式将
EventChannel、BasicMessageChannel、MethodChannel写在了flutter_bridge_manager.dart文件里
- 向原生发送信息
// 这个字典紧紧是为了举个例子
Map<String, dynamic> map = {"name": listTitleArray[index], "arguments": "test"};
MethodChannelManager.instance.methodChannel
.invokeMethod(listTitleArray[index], map);- 接收native发来的信息
BasicMessageChannelManager.instance.basicMessageChannel.setMessageHandler((message) async {
Map map = json.decode(message);
print('basicMessageMethod:' + '$map');
});
