1. 自定义tabbar效果

2. pages新建tabbar页面

1. 首先在 pages.json 文件中，新建一个 tabbar 页面

"pages": [ //pages数组中第一项表示应用启动页，参考：https://uniapp.dcloud.io/collocation/pages
	{
		"path": "pages/index/tabbar",
		"style": {
			"navigationBarTitleText": "tabbar页面",
			"navigationStyle": "custom"
		}
	},
	.....// 其他页面
],

3. tabbar 页面结构

1. 此页面主要是写 tabbar的html样式和布局，引用主页面代码，通过 v-if 控制进行展示 index，search，maim，news，me 一级页面

4. tabbar 页面完整代码

1. css 样式文件太多了就不贴出来了
