uniapp滑动页面切换和下拉刷新，触底加载更多（swiper + scroll-view）_uniapp swiper 下拉刷新

因为官方文档乱七八糟的，所以自己来总结下

需求：

常见的上方tag标签切换，下方是页面，上面点击切换，下面页面也切换，下方列表有下拉刷新，触底加载更多
因为这两个组件都是固定高度的，所以没办法用页面的触底，
因为有的页面不是列表，所以没办法用uniapp的下拉页面刷新生命周期
所以用uniapp的swiper轮播图来切换，轮播图固定高度，里面列表用 scroll-view来做下拉刷新和触底加载更多

代码：

开头有用到uviewUI框架的u-navbar头部，不需要的可以自己删了
