我想在 Realm 中使用 Jitsi-Meet(视频通话库)。当我在 iOS 上运行应用程序时,Realm 不起作用。它显示以下错误:

2018-12-28 16:22:34.504 [error][tid:main][RCTModuleData.mm:179] Realm has no setter or ivar for its bridge, which is not permitted. You must either @synthesize the bridge property, or provide your own setter method.

如果我删除 Jisti-Meet 库,Realm 可以正常工作。Jitsi-Meet 在没有领域的情况下也能正常工作。

重现步骤

  1. 创建一个新的 react-native 应用程序:react-native init AwesomeProject
  2. 安装领域-js:npm install realm --savereact-native link realm
  3. 安装 React Native Jisti Meet:npm install react-native-jitsi-meet --save
  4. 在 Build setting 下将Dead Code Stripping设置为 No,将Enable Bitcode设置为 No 并将Always Embed Swift Standard Libraries设置为 Yes
  5. 添加node_modules/react-native-jitsi-meet/ios/WebRTC.frameworknode_modules/react-native-jitsi-meet/ios/JitsiMeet.framework嵌入二进制文件。
  6. 选择Build Settings,找到Search Paths。编辑 BOTHFramework Search PathsLibrary Search Paths. 并在两个部分上添加路径:$(SRCROOT)/../node_modules/react-native-jitsi-meet/ioswithrecursive

现在运行应用程序,应用程序将显示错误。

代码示例

文件名:App.js

import React, {Component} from 'react';
import {Platform, StyleSheet, Text, View, Button} from 'react-native';
import Realm from 'realm';

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',
});


type Props = {};
export default class App extends Component<Props> {

  constructor(props) {
    super(props);
    this.state = { realm: null };
  }


  componentWillMount() {
    Realm.open({
      schema: [{name: 'Dog', properties: {name: 'string'}}]
    }).then(realm => {
      realm.write(() => {
        realm.create('Dog', {name: 'Rex'});
      });
      this.setState({ realm });
    });
  }

  render() {

    const info = this.state.realm
    ? 'Number of dogs in this Realm: ' + this.state.realm.objects('Dog').length
    : 'Loading...';


    return (
      <View style={styles.container}>
        <Text style={styles.welcome}>Welcome to React Native!</Text>
        <Text style={styles.instructions}>To get started, edit App.js</Text>
        <Text style={styles.instructions}>{instructions}</Text>
        <Button title="Video" 
        // onPress = {() => initiateVideoCall()} 
        />
        <Text style={styles.welcome}>
          {info}
        </Text>
      </View>
    );
  }
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
    backgroundColor: '#F5FCFF',
  },
  welcome: {
    fontSize: 20,
    textAlign: 'center',
    margin: 10,
  },
  instructions: {
    textAlign: 'center',
    color: '#333333',
    marginBottom: 5,
  },
});

领域和工具的版本

  • Realm JS SDK 版本:2.21.1(低版本也有同样的问题)
  • 节点或 React Native:RN 0.57.8
  • 客户端操作系统和版本:iOS Real Device - 12.1.2
  • MacOS:10.13.6 高山脉
  • React Native 的调试器:无
