推荐使用React Native FBSDK：社区驱动的Facebook SDK集成方案

import React from 'react';
import {
  Platform,
  StyleSheet,
  Text,
  View
} from 'react-native';
 
import {
  LoginButton,
  AccessToken,
  GraphRequest,
  GraphRequestManager
} from 'react-native-fbsdk';
 
export default class LoginScreen extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      userInfo: null
    };
  }
 
  componentDidMount() {
    AccessToken.getCurrentAccessToken().then(
      (data) => {
        if (data) {
          this._fetchUserInfo();
        }
      }
    );
  }
 
  _fetchUserInfo() {
    const infoRequest = new GraphRequest(
      '/me',
      null,
      this._responseInfoCallback
    );
    new GraphRequestManager().addRequest(infoRequest).start();
  }
 
  _responseInfoCallback = (error, result) => {
    if (error) {
      console.log('Error fetching data: ', error);
    } else {
      this.setState({
        userInfo: result
      });
    }
  };
 
  render() {
    return (
      <View style={styles.container}>
        <LoginButton
          readPermissions={['public_profile', 'email']}
          onLoginFinished={
            (error, result) => {
              if (error) {
                console.log('Login failed with error: ' + error.message);
              } else if (result.isCancelled) {
                console.log('Login was cancelled');
              } else {
                console.log('Login was successful with permissions: ' + result.grantedPermissions);
                this._fetchUserInfo();
              }
            }
          }
        />
        <Text style={styles.welcome}>
          {this.state.userInfo ? JSON.stringify(this.state.userInfo) : 'No user info'}
        </Text>
      </View>
    );
  }
}
 
const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
  },
  welcome: {
    margin: 10,
    textAlign: 'center',
    color: '#333333',
  },
});

这段代码展示了如何在React Native应用中集成和使用Facebook SDK来实现用户登录，并获取用户的基本信息。代码使用了react-native-fbsdk库中的LoginButton和GraphRequest来简化登录流程和用户信息的获取。同时，它提供了一个简洁的用户界面来显示登录状态和用户信息。
