本次主要是关于json的全局配置部分（导航栏等）

app.json:

{
  "pages":[
    "pages/swiper/swiper",
    "pages/logs/logs",
    "pages/test/test",
    "pages/form/form",
    "pages/scroll-view/scroll-view",
    "pages/navigator/navigator",
    "pages/images/images",
    "pages/view/view",
   
    "pages/index/index",
    "pages/Navi_pack/1/1",  
    "pages/Navi_pack/2/2",
    "pages/Navi_pack/3/3",
    "pages/Navi_pack/4/4",
    "pages/Navi_pack/5/5"

  ],
  
  "window":{
    "backgroundTextStyle":"dark",
    "navigationBarBackgroundColor": "#fff",
    "navigationBarTitleText": "studyProRecord",
    "navigationBarTextStyle":"black",
    "navigationStyle":"default",
    "backgroundColor": "#555555",
    "enablePullDownRefresh":true
  },  
  "tabBar": {
    
    "color": "#c39",
    "selectedColor": "green",
    "borderStyle": "white",
    "list": [
     {
      "pagePath": "pages/swiper/swiper",
      "iconPath": "pictures/健康.png",
      "selectedIconPath": "pictures/star.png",
      "text": "love"

     },{
      "pagePath": "pages/form/form",
      "iconPath": "pictures/完成.png",
      "selectedIconPath": "pictures/star.png",
      "text": "你好"
       },{
       "pagePath": "pages/scroll-view/scroll-view",
       "text": "scroll-view",
       "iconPath": "pictures/平台.png",
       "selectedIconPath": "pictures/star.png"
     }
    ]
  },

  "style": "v2",
  "sitemapLocation": "sitemap.json"
  
}

主要使用tabBar来设置导航栏

color 设置底部 text 的颜色

selectedColor 是设置导航被选中时的颜色

另外 list 列表中放入 各个想要设置的导航部分

pagePath 即要跳转的页面（类似导航）

iconPath 即显示出来的图标

selectedIconPath 即选中后变化为的图标

text 底部的文字部分
