React Native 通知 DeviceEventEmitter

1. A页面注册监听事件,别忘了在组件销毁的时候将其移除

import {DeviceEventEmitter} from 'react-native';

componentDidMount() {
    this.listener = DeviceEventEmitter.addListener('xxxName',(param) => {
        
    });
}

componentWillUnmount(){
    this.listener.remove();
}

2. B页面发送一个通知

import {DeviceEventEmitter} from "react-native"

DeviceEventEmitter.emit('xxxName',param);
