微信小程序之（天气预报）

这个案例是仿UC中天气界面做的中间也有点出入，预留了显示当前城市名字和刷新图标的位置，自己可以写下，也可以添加搜索城市。值得注意的是100%这个设置好像已经不好使了，可以通过获取设备的高度通过数据绑定设置高度。地址：https://github.com/shuncaigao/Weather

界面主要分为四部分：

第一部分

这里是预留的一块可以自行添加补充下

<view class="newTopView"><!--左边添加当前城市名字，点击跳转选择城市 右边添加刷新当前天气--></view>

PS：

开发者工具无法显示问题：是因为View没有获得高度，默认个高度或者直接修改wxml中height高度即可
