9、底部导航添加图标和选中颜色

在app.json中全局配置：

"tabBar":{
    "list":[
      {
        "pagePath": "pages/index/index",
        "text": "首页",
        "iconPath": "./images/tabBar1.png",
        "selectedIconPath": "./images/tabBar11.png"
      },{
          "pagePath": "pages/logs/logs",
          "text": "日志",
          "iconPath": "./images/tabBar2.png",
          "selectedIconPath": "./images/tabBar22.png"
      },
      {
        "pagePath": "pages/my/my",
        "text": "我的",
        "iconPath": "./images/tabBar3.png",
        "selectedIconPath": "./images/tabBar33.png"
      }
    ]
  },

图标可在阿里提供的iconfont图标库中下载。
