RN与原生的通信记录

此文以iOS与RN通信为例实现了 1.RN给原生发消息：RN调用原生方法，传递参数  原生中导出MODULE和METHOD供RN调用 RCT_EXPORT_MODULE(PushNative) // RN跳转原生界面 RCT_EXPORT_METHOD(RNOpenChatVCWithUserInfo:(NSDictionary *)userInfo){     dispatch_async(dispatch_get_main_queue(), ^{       RootTabBarController *tabBar = [RootTabBarController new];       AppDelegate *app = (AppDelegate *)[[UIApplication sharedApplication] delegate];       [app.nav pushViewController:tabBar animated:NO];     });   }

RN中 先导入，再调用 import { ..., NativeModules } from 'react-native' NativeModules.PushNative.RNOpenChatVCWithUserInfo(UserInfo)

2.原生给RN发消息：原生通讯类发出消息事件，RN中捕捉 原生发出消息事件 PushNative * pushNative = [PushNative shareInstance];
[pushNative sendEventWithName:@"onCloseWithIndex" body:@{@"selIndex": @0}]; RN中 import {...,NativeModules,NativeEventEmitter} from 'react-native' const PushNativeEmitter = new NativeEventEmitter(NativeModules.PushNative); this.listener = PushNativeEmitter.addListener('onCloseWithIndex', (obj) => { // 处理 }
