微信小程序--TabBar不出现

今天打算开始实战一个微信小程序项目,一开始就踩坑了,正确设置了TabBar,但是TabBar就是不能显示出来,后面才找到原因,这里记录下:

app.json正确代码:

{
  "pages":[
    "pages/index/index", 
    "pages/leader/leader",    
    "pages/leader/stories/stories", 
    "pages/leader/authors/authors", 
    "pages/stack/stack",
    "pages/stack/booklist/booklist", 
    "pages/stack/booklist/bookdetail/bookdetail",
    "pages/bookdesk/bookdesk", 
    "pages/mine/mine",
    "pages/mine/news/news",    
    "pages/logs/logs" 
  ],
  "window":{
    "backgroundTextStyle":"light",
    "navigationBarBackgroundColor": "#fff",
    "navigationBarTitleText": "网易蜗牛读书",
    "navigationBarTextStyle":"black"
  },
  "tabBar":{
    "color":"#999999",
    "selectedColor":"#444444",
    "backgroungColor":"#ffffff",
    "borderStyle":"#e0e0e0",
    "list": [
      {
        "pagePath":"pages/leader/leader",
        "iconPath": "assets/icons/lingdu.png",
        "selectedIconPath": "assets/icons/lingdu_sel.png",
        "text":"领读"
      },
      {
        "pagePath":"pages/stack/stack",
        "iconPath": "assets/icons/stack.png",
        "selectedIconPath": "assets/icons/stack_sel.png",
        "text":"分类"
      },
      {
        "pagePath": "pages/bookdesk/bookdesk",
        "iconPath": "assets/icons/bookdesk.png",
        "selectedIconPath": "assets/icons/bookdesk_sel.png",
        "text":"书桌"
      },
      {
        "pagePath":"pages/mine/mine",
        "iconPath": "assets/icons/mine.png",
        "selectedIconPath": "assets/icons/mine_sel.png",
        "text":"我的"
      }
    ]
  }
}

这里注意显示解决有两种方式:

1.pages里的首个页面必须在list数组里有配置,所以在lists数组里加一个字典对象即可。

{
        "pagePath":"pages/index/index",
        "iconPath": "assets/icons/index.png",
        "selectedIconPath": "assets/icons/index_sel.png",
        "text":"首页"
 }

但是我的TabBar又不想有这个item显示,这里看第二种解决办法。

2.pages数组的第一项必须是tabBar的list数组的一员:

这里有个疑惑:

百度了解决方法,显示将list数组加了index的模块item,后面不想要index模块在TabBar显示,然后又删除再运行,问题就解决了,也没有设置pages数组的第一项必须是tabBar的list数组的一员。

解决了就好,知道的大神可以留言告诉我哟!
