RN版聊天App仿微信实例

9月,又到开学的季节。为每个一直默默努力的自己点赞!最近都沉浸在react native原生app开发中,之前也有使用vue/react/angular等技术开发过聊天室项目,另外还使用RN技术做了个自定义模态弹窗rnPop组件。

一、项目简述

基于react+react-native+react-navigation+react-redux+react-native-swiper+rnPop等技术开发的仿微信原生App界面聊天室——RN_ChatRoom,实现了原生app启动页、AsyncStorage本地存储登录拦截、集成rnPop模态框功能(仿微信popupWindow弹窗菜单)、消息触摸列表、发送消息、表情(动图),图片预览,拍摄图片、发红包、仿微信朋友圈等功能。

二、技术点

MVVM框架:react / react-native / react-native-cli

状态管理:react-redux / redux页面导航:react-navigationrn

弹窗组件:rnPop打包工具:webpack 2.0轮播组件:react-native-swiper

图片/相册:react-native-image-picker

◆ App全屏幕启动页splash模板

react-native如何全屏启动? 设置StatusBar顶部条背景为透明 translucent={true},并配合RN动画Animated

/** * @desc 启动页面 */ import React, { Component } from 'react' import { StatusBar, Animated, View, Text, Image } from 'react-native' export default class Splash extends Component{ constructor(props){ super(props) this.state = { animFadeIn: new Animated.Value(0), animFadeOut: new Animated.Value(1), } } render(){ return ( <Animated.View style={[GStyle.flex1DC_a_j, {backgroundColor: '#1a4065', opacity: this.state.animFadeOut}]}> <StatusBar backgroundColor='transparent' barStyle='light-content' translucent={true} /> <View style={GStyle.flex1_a_j}> <Image source={require('../assets/img/ic_default.jpg')} style={{borderRadius: 100, width: 100, height: 100}} /> </View> <View style={[GStyle.align_c, {paddingVertical: 20}]}> <Text style={{color: '#dbdbdb', fontSize: 12, textAlign: 'center',}}>RN-ChatRoom v1.0.0</Text> </View> </Animated.View> ) } componentDidMount(){ // 判断是否登录 storage.get('hasLogin', (err, object) => { setTimeout(() => { Animated.timing( this.state.animFadeOut, {duration: 300, toValue: 0} ).start(()=>{ // 跳转页面 util.navigationReset(this.props.navigation, (!err && object && object.hasLogin) ? 'Index' : 'Login') }) }, 1500); }) } }
