我使用 react-native 来分享我在 mycode 中写的

   const FBSDK = require('react-native-fbsdk');

import React, { Component } from 'react';
import {
  AppRegistry,
  StyleSheet,
  Text,
  TouchableHighlight,
  View,
} from 'react-native';
const {
  LoginButton,
  ShareDialog,
} = FBSDK;

class HelloFacebook extends Component {
  constructor(props) {
    super(props);
    const shareLinkContent = {
      contentType: 'link',
      contentUrl: 'https://www.facebook.com',
      contentDescription: 'Wow, check out this great site!',
    };

    this.state = {
      shareLinkContent: shareLinkContent,
    };
  }

  shareLinkWithShareDialog() {
    var tmp = this;
    ShareDialog.canShow(this.state.shareLinkContent).then(
      function(canShow) {
        if (canShow) {
          return ShareDialog.show(tmp.state.shareLinkContent);
        }
      }
    ).then(
      function(result) {
        if (result.isCancelled) {
          alert('Share cancelled');
        } else {
          alert('Share success with postId: '
            + result.postId);
        }
      },
      function(error) {
        alert('Share fail with error: ' + error);
      }
    );
  }

  render() {
    alert("render")
    return (
      <View style={styles.container}>
        <LoginButton />
        <TouchableHighlight style={styles.share}
          onPress={this.shareLinkWithShareDialog.bind(this)}>
          <Text style={styles.shareText}>Share link with ShareDialog</Text>
        </TouchableHighlight>
      </View>
    );
  }
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
    backgroundColor: '#F5FCFF',
  },
  shareText: {
    fontSize: 20,
    margin: 10,
  },
});

AppRegistry.registerComponent('HelloFacebook', () => HelloFacebook);

但是这里的输出我只得到了我想分享的链接，我没有得到任何我想分享的描述 我需要的是： 我想分享 contentDescription 和 contentUrl，所以请任何人给我建议我的代码有什么问题吗，非常感谢任何帮助
