我正在尝试构建导航,当我添加
时遇到问题{
initialRouteName: 'Loading',
}
当我使用没有initialRouteName的stacknavigator时,一切正常。我正在进行ios仿真(本机运行ios),并且已经尝试过几次Pod安装。
这是app.js
import React from 'react';
import Loading from './Loading';
import SignUp from './SignUp';
import Login from './Login';
import Main from './Main';
import { createAppContainer } from 'react-navigation';
import { createStackNavigator } from 'react-navigation-stack';
const AppNavigator = createStackNavigator(
{
Home: Loading,
Home: SignUp,
Home: Login,
Home: Main,
},
{
initialRouteName: 'Loading',
}
);
export default createAppContainer(AppNavigator);
这是错误:
TypeError: undefined is not an object (evaluating 'routeConfigs[initialRouteName].params')
This error is located at:

有人知道这个问题可能是什么吗?
非常感谢!

据我所知,initialroutename使用的是索引名称,而不是屏幕名称。在您的项目中,您必须使用“主页”。
因此您必须在屏幕之间使用不同的名称。喜欢,
const AppNavigator = createStackNavigator(
{
loading: Loading,
signUp: SignUp,
login: Login,
main: Main,
},
{
initialRouteName: 'loading',
}
);
此外,我认为将名称“ Home”用于四个屏幕是一个非常糟糕的主意。您必须尝试在屏幕之间使用不同的名称。

更改此内容:
{
initialRouteName: 'Loading',
}
收件人:
{
initialRouteName: 'Home',
}
屏幕键应作为参数传递给initialRouteName

谢谢,我确实不是在指屏幕。
