项目 中 采用React Native 开发 ，观看直播调用iOS 原生接口
RN代码
import React,{ Component } from 'react'; import { Platform,StyleSheet,Text,View,TouchableHighlight,NativeModules,NativeEventEmitter,} from 'react-native'; const instructions = Platform.select({ ios: 'Press Cmd+R to reload,\n' + 'Cmd+D or shake for dev menu',android: 'Double tap R on your keyboard to reload,\n' + 'Shake or press menu button for dev menu',}); var nativeBridge = NativeModules.RNIOSWatchLiveExportJsToReact; const NativeModule = new NativeEventEmitter(nativeBridge); export default class App extends Component<{}> { render() { return ( <View style={styles.container}> <Text style={styles.welcome}> Welcome to 北京四中网校! </Text> <TouchableHighlight style = {styles.btn} onPress = {this._pressBackButton.bind(this)}> <Text style={styles.btnText}> 看直播 </Text> </TouchableHighlight> </View> ); } _pressBackButton () { const options = { domain:"etiantian.gensee.com",roomNumber:"78608221",nickName:"etiantian",watchPassword :"933767" } NativeModule.addListener('watchLiveOpertion',(data)=>this._watchLiveHandle(data)); NativeModules.watchLive.watchLive(options,(data)=>this._watchLiveHandle(data)); } _watchLiveHandle(response) { console.log("result",response); if (response.close) { NativeModule.removeAllListeners('watchLiveOpertion'); console.log('结束直播观看'); } else if (response.error) { NativeModule.removeAllListeners('watchLiveOpertion'); console.log('观看失败：',response.error); }else { console.log('观看成功'); } } }
