reactNative开发移动端
用reactNative（VsCode编译器）开发移动端界面，Android开发后端接口（Android Studio编译器）。
reactNative界面开发
reactNative提供组件，或者使用第三方库提供的组件，数据(包含规则校验)由 yup、formik提供，除启动界面：login,register,splash等账户登录后，一般使用导航栏（@react-navigation/drawer、'npm install react-native-gesture-handler react-native-reanimated'）包含抽屉（Drawer Navigator）、tab切换（Bottom Tabs Navigator）进行路由导航（一般适用于简单页面切换），详情API请看https://reactnavigation.org/docs/drawer-navigator
前端init.bat文件部分组件
js
rem 界面基础组件
yarn add react-native
yarn add @ant-design/react-native
rem 界面数据(formik)与表单验证(Yup验证规则)
npm install yup
npm install formik
rem 统一样式模板
yarn add @shopify/restyle
rem 其他组件（第三方）
yarn add react-native-keyboard-aware-scroll-view
rem 菜单导航栏
yarn add @react-navigation/drawer
yarn add react-native-gesture-handler react-native-reanimatedRN问题记录
1、使用theme.js写的公共组件报错（funcMap[props] undefined）
原因 ：import @shopify/restyle没有定义 <ThemeProvider theme={theme}></ThemeProvider>
解决方式 ：在根页面定义<ThemeProvider theme={theme}><ThemeProvider>,或单独使用的页面也要加这个。
案例如下
描述： 导航页TCPZDrawerNavigator.js引入ThemeProvider标签；使用页面YDLXDTList.js应用组件LableValueInput；定义公共组件LableValueInput.js（使用了@shopify/restyle、theme）
使用公共组件和统一样式:代码只包含使用公用组件LableValueInput用法，样式部分可能会报错，需要修改
js
import React, { useState } from 'react';
import * as Yup from 'yup';
import { Formik, useFormik, useField } from 'formik';
// 原生接口
import { YDLXDTService, RunActivity } from '~/native/nativeModules';
import {Container,Button,Box,CusCheckbox,Header,UserContext,LableValueInput,ConfirmModal, Error} from '~/components'
//模板校验规则
const ydlxdtSchema = Yup.object().shape({
mc: Yup.string()
// 只能输入数字、字母、汉字
.matches( /^[\da-zA-Z\u4E00-\u9FA5]+$/u,'图层名称存在违规字符，请重新输入！')
.required('图层名称必填'),
lx: Yup.string()
.matches( /^[\da-zA-Z_\u4E00-\u9FA5\-.]+$/u,'矢量数据类型存在违规字符，请重新输入！'),
address: Yup.string()
.matches( /^[\da-zA-Z_\u4E00-\u9FA5\-.]+$/u,'详细地址存在违规字符，请重新输入！')
.required('详细地址必填'),
dh: Yup.string()
.matches( /^[\da-zA-Z_\u4E00-\u9FA5\-.]+$/u,'地号存在违规字符，请重新输入！'),
zValue: Yup.string()
.matches( /^[\da-zA-Z\u4E00-\u9FA5]+$/u,'证书编号的字存在违规字符，请重新输入！')
.required('证书编号的字必填'),
hValue: Yup.string()
.matches( /^[\da-zA-Z\u4E00-\u9FA5]+$/u,'证书编号的号存在违规字符，请重新输入！')
.required('证书编号的号必填'),
syqmj: Yup.number(),
page: Yup.number().min(1),
});
