问题：UniApp设置tabBar，解决界面不显示,
根据官方文档，在 pages.json 中提供 tabBar 配置，
"tabBar": {
"color": "#7A7E83",
"selectedColor": "#3cc51f",
"borderStyle": "black",
"backgroundColor": "#ffffff",
"list": [{
"pagePath": "pages/component/index",
"iconPath": "static/image/icon_component.png",
"selectedIconPath": "static/image/icon_component_HL.png",
"text": "组件"
}, {
"pagePath": "pages/API/index",
"iconPath": "static/image/icon_API.png",
"selectedIconPath": "static/image/icon_API_HL.png",
"text": "接口"
}]
}
界面没显示，检查了代码，pages第一个选项和我的tabBar第一个的选项是同一个页面，但是没显示，不是这个问题。
解决方法：
一：pagePath不能是相对路径，必须是pages里的path保持一致
是自己写的tabBar的pagePath写了绝对路径，改正之后，能显示了
"list": [
{
"pagePath": "pages/home/index",
"iconPath": "./images/home-off.png",
"selectedIconPath": "./images/home-on.png",
"text": "首页"
},
{
"iconPath": "./images/ic_catefory_normal.png",
"pagePath": "pages/category/index",
"text": "分类",
"selectedIconPath": "./images/ic_catefory_pressed.png"
},
]
