import React from 'react';
import { Scene, Router} from 'react-native-router-flux';
import LoginForm from '../../components/components/LoginForm';
const RouterComponent = () => {
return (
<Router>
<Scene key = "login" component = {LoginForm} title = "Please Login"/>
</Router>
);
};
export default RouterComponent;
实际上,您需要将场景包装在根场景中 <Scene key="root">
,文档中未提及。
因此您的 RouterComponent 如下所示:
const RouterComponent = () =>{
return(
<Router>
<Scene key="root" >
<Scene key="login" component ={LoginForm} title="Please Login"/>
</Scene>
</Router>
);
};
首先检查你的react-native-router-flux的版本。如果版本
是 3,用 <Scene key="root" >
:
包裹你的 <Scene>
const RouterComponent = () => {
return (
<Router>
<Scene key="root">
<Scene key="login" component={LoginForm} title="Please Login" />
</Scene>
</Router>
);
};
对于版本 4,将 <Scene key="root">
替换为 <Stack key="root">
,并且不要忘记导入 import {Stack} from 'react-native-router-flux
:
import { Router, Scene, Stack } from 'react-native-router-flux';
const RouterComponent = () => {
return (
<Router>
<Stack key="root">
<Scene key="login" component={LoginForm} title="Please Login" />
</Stack>
</Router>
);
};
只需将当前场景添加到另一个场景中,使用 key="root"
<Scene key="root" >
<Scene
key="login"
component={LoginForm}
title="Please Login"/>
</Scene>
