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！
