uni-app+vue仿微信聊天APP界面|uniapp仿微信朋友圈
基于uniapp+vue仿微信聊天室uniapp-chatroom项目，vue语法及类似小程序api开发原生APP应用，实现了发送图文消息、表情(gif动图)，图片预览、地图位置、红包、仿微信朋友圈等功能。
H5 / 小程序 / App端测试效果如下 (后续大图统一展示App端)
技术实现
- 编辑器：HBuilder X
- 技术框架：uni-app + vue
- 状态管理：Vuex
- iconfont图标：阿里字体图标库
- 自定义导航栏 + 底部Tabbar
- 弹窗组件：uniPop（基于uni-app封装模态弹窗）
- 测试环境：H5端 + 小程序 + App端（三端均兼容）
- 高德地图：vue-amap

如何实现微信朋友圈页面向下滚动，顶部导航栏由透明变背景色
通过onPageScroll函数实现自定义导航上下滑动自动调整导航栏的透明度，滑动到距离顶部200 效果如下图二
