react-native导航路由未定义

Question

启动我的应用时出错： 未定义不是对象（评估＆＃39; route.title＆＃39;）

我希望导航器能够通过“设置”来初始化。路线，因为我是initalRoute = {{title：＆＃39;设置＆＃39;}}

如何在初始应用加载时定义路由？

＆＃13;

＆＃13;

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

import SetupComponent from './src/setup/setup.component';
import HomeComponent from './src/home/home.component';

export default class AwesomeProject extends Component {
  render() {
    return (
      <Navigator
        initalRoute={{ title: 'Setup'}}      
        renderScene={(route, navigator) => {
        console.log("routing", route.title);

          if (route.title === 'Setup'){
            return <SetupComponent navigator={navigator} />
          }
          if (route.title === 'Home') {
            return <HomeComponent navigator={navigator} />
          }        
           console.log("return default");
      
        }}
      />        
    
    );
  }
}
AppRegistry.registerComponent('AwesomeProject', () => AwesomeProject);

您的导航器组件定义中存在拼写错误 - 您的代码应为initalRoute时应为initialRoute。更改此行，您应该会看到错误已修复。
