微信小程序分享：TabBar不出现如何处理

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！
