首先我们需要搭建一个 Tabbar，在搭建之前我们将需要跳转的页面创建一下待会需要使用到。
创建 me 我的页面，在 pages 当中鼠标右键新建页面即可，在新建一个 order 订单页面，更改 app.json 配置添加 tabBar 配置项：
{
"tabBar": {
"color": "#000000",
"backgroundColor": "#000000",
"list": [
{
"pagePath": "pages/index/index",
"text": "首页",
"iconPath": "/assets/images/cart.png",
"selectedIconPath": "/assets/images/cart-active.png"
},
{
"pagePath": "pages/order/order",
"text": "订单",
"iconPath": "/assets/images/cart.png",
"selectedIconPath": "/assets/images/cart-active.png"
},
{
"pagePath": "pages/me/me",
"text": "我的",
"iconPath": "/assets/images/user.png",
"selectedIconPath": "/assets/images/user-active.png"
}
]
}
}
