screen shot of error React Native：

  

使用fbsdk时可能出现未处理的承诺拒绝

显示出上述错误的黄色屏幕。我尝试了很多调试这个，但dint工作很友好请帮我调试这个错误。

我的代码：

import React, { Component } from 'react';
import {
  AppRegistry,
  StyleSheet,
  Text,
  View,
  TouchableOpacity,
} from 'react-native';

import FBSDK, { LoginManager } from 'react-native-fbsdk'

export default class fbappss extends Component {


   _fbAuth(){

        LoginManager.logInWithReadPermissions(['public_profile']).then(function(result){

          if (result.isCancelled) {

              console.log('Login was cancelled'); 
          } else {

              console.log('Login was a success' + result.grantedPermission.toString());
          }
        }, function(error) {

            console.log('an error occured:' +error);
        })

        }

  render() {
    return (
      <View>
        <TouchableOpacity onPress={this._fbAuth()}>
        <Text>facebook</Text>
        </TouchableOpacity>
      </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,
  },
});

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