Ios ReactNative-如何在ViewController中调用函数

我是ReactNative新手，我正在尝试将ReactNative集成到我当前的项目中

在my ViewController中包含RCTrotView和实现如下的代码：

ViewController.swift

override func viewDidLoad() {
    super.viewDidLoad()        
    .....
        let bridge = RCTBridge(bundleURL: jsCodeLocation, moduleProvider: nil, launchOptions: nil)

        let reactRootView = RCTRootView(bridge: bridge, moduleName: "Index", initialProperties: props)

        self.view.addSubview(reactRootView);
        reactRootView.frame = self.view.bounds
        reactRootView.delegate = self;
    ....     
}

func onReactEvent(event :NSDictionary , callback: RCTResponseSenderBlock) {}

@objc func sendCustomEventToHost(event: NSDictionary, callback: RCTResponseSenderBlock) -> Void {}

let bridge = RCTBridge(bundleURL: jsCodeLocation, moduleProvider: nil, launchOptions: ["controller":self"])

let controller = self.bridge.launchOptions["controller"]

反应管理器。swift

override func viewDidLoad() {
    super.viewDidLoad()        
    .....
        let bridge = RCTBridge(bundleURL: jsCodeLocation, moduleProvider: nil, launchOptions: nil)

        let reactRootView = RCTRootView(bridge: bridge, moduleName: "Index", initialProperties: props)

        self.view.addSubview(reactRootView);
        reactRootView.frame = self.view.bounds
        reactRootView.delegate = self;
    ....     
}

func onReactEvent(event :NSDictionary , callback: RCTResponseSenderBlock) {}

@objc func sendCustomEventToHost(event: NSDictionary, callback: RCTResponseSenderBlock) -> Void {}

let bridge = RCTBridge(bundleURL: jsCodeLocation, moduleProvider: nil, launchOptions: ["controller":self"])

let controller = self.bridge.launchOptions["controller"]

因此，我如何在我的视图控制器中调用onReactEvent（）函数，从ReactNativeManager中的函数sendCustomEventToHost（）。

谢谢

在

ReactNativeManager

中，您必须创建ViewController的实例。 例如：

let viewC = ViewController()

然后你只要打电话：

viewC.onReactEvent(....)

我知道如何使用启动选项将ViewController传递给ReactNativeManager

ViewController.swift

override func viewDidLoad() {
    super.viewDidLoad()        
    .....
        let bridge = RCTBridge(bundleURL: jsCodeLocation, moduleProvider: nil, launchOptions: nil)

        let reactRootView = RCTRootView(bridge: bridge, moduleName: "Index", initialProperties: props)

        self.view.addSubview(reactRootView);
        reactRootView.frame = self.view.bounds
        reactRootView.delegate = self;
    ....     
}

func onReactEvent(event :NSDictionary , callback: RCTResponseSenderBlock) {}

@objc func sendCustomEventToHost(event: NSDictionary, callback: RCTResponseSenderBlock) -> Void {}

let bridge = RCTBridge(bundleURL: jsCodeLocation, moduleProvider: nil, launchOptions: ["controller":self"])

let controller = self.bridge.launchOptions["controller"]

访问 反应管理器。swift

override func viewDidLoad() {
    super.viewDidLoad()        
    .....
        let bridge = RCTBridge(bundleURL: jsCodeLocation, moduleProvider: nil, launchOptions: nil)

        let reactRootView = RCTRootView(bridge: bridge, moduleName: "Index", initialProperties: props)

        self.view.addSubview(reactRootView);
        reactRootView.frame = self.view.bounds
        reactRootView.delegate = self;
    ....     
}

func onReactEvent(event :NSDictionary , callback: RCTResponseSenderBlock) {}

@objc func sendCustomEventToHost(event: NSDictionary, callback: RCTResponseSenderBlock) -> Void {}

let bridge = RCTBridge(bundleURL: jsCodeLocation, moduleProvider: nil, launchOptions: ["controller":self"])

let controller = self.bridge.launchOptions["controller"]

希望这有帮助

因为我想在之前初始化的ViewController中使用一些变量。代码“let viewC=ViewController（）”将初始化具有不同地址的新控制器。我不知道如何调用父ViewController的方法，该父ViewController包含从ViewController推送的RCTrootViewArractNativeManager？ReactNativeManager类继承自RCTBridgeModule，由React Native view启动，其方法由React Native view调用。
