1、我们第一步需要新建一个文件夹photo，将已经准备好了的图标放在文件夹内。
2、打开app.json，新建tabber项。代码如下："pagePath":"此处填页面的根目录","text":"此处填文本，如“首页","iconPath":"此处填的是图标路径","selectedIconPath":"此处填的是被选中时的图标路径"。
3、完成一个tabber界面至少需要两个页面，两个图标。如果需要四个，代码示例如下："tabB锾攒揉敫ar":{"selectedColor":"#C00000","list":[{"pagePath":"pages/home/home","text":"首页","iconPath":"/static/static/tab_icons/home.png","selectedIconPath":"/static/static/tab_icons/home-active.png"},{"pagePath":"pages/cate/cate","text":"分类","iconPath":"/static/static/tab_icons/cate.png","selectedIconPath":"/static/static/tab_icons/cate-active.png"},{"pagePath":"pages/cart/cart","text":"购物车","iconPath":"/static/static/tab_icons/cart.png","selectedIconPath":"/static/static/tab_icons/cart-active.png"},{"pagePath":"pages/my/my","text":"我的","iconPath":"/static/static/tab_icons/my.png","selectedIconPath":"/static/static/tab_icons/my-active.png"}]
