微信小程序tabBar不显示的问题

刚接触小程序，发现根据官网配置app.json后死活不出现下方tabBar。总结一下这里面的坑

1、必要属性检查。tabBar中color、selectedColor、backgroundColor、list四个属性是必填的！

2、list最少2个，最多5个

3、也是最坑的一个，pages数组的第一项必须在list中，我测试的时候就死在这里

示例：

{
  "pages":[
    "pages/index/index",(第一项必须为list中任意一个元素的pagePath)

    "pages/logs/logs",
    "pages/function/function",
    "pages/pay/pay",
    "pages/account/account"
  ],
  "tabBar": {
    "color": "#dddddd",
    "selectedColor": "#3cc51f",
    "borderStyle": "black",
    "backgroundColor": "#ffffff",
    "list": [{
      "pagePath": "pages/logs/logs",
      "iconPath": "assets/images/icon_component.png",
      "selectedIconPath": "assets/images/icon_component_HL.png",
      "text": "组件"
    }, {
      "pagePath": "pages/index/index",
      "iconPath": "assets/images/icon_API.png",
      "selectedIconPath": "assets/images/icon_API_HL.png",
      "text": "接口"
    }]
  },
  "window":{
    "navigationBarBackgroundColor": "#6595e9",
    "navigationBarTextStyle":"white",
    "navigationBarTitleText": "Vision's Program",
    "backgroundColor": "#eeeeee",
    "backgroundTextStyle":"light"
  }
}

PS：后来还注意到有些小伙伴把”tabBar”写成”tabbar”导致不显示的，要细心哟~
