1. 实现效果

2. 提示组件

1. 在 components 中新增 struggler-uniapp-add-tip 提示添加小程序 组件
2. 默认展示，通过点击将 SHOW_TIP 存储本地进行隐藏

<template>
	<view>
		<view class="uni-add-tips-box" v-if="showTip">
		  <view class='uni-add-tips-content' @tap='hideTip'>
		    <text>{{tip}}</text>
		  </view>
		</view>
	</view>
</template>

<script>
	const SHOW_TIP = "SHOW_TIP"
	export default{
		data(){
			return{
				showTip:false,
			}
		},
		mounted() {
			this.showTip = !uni.getStorageInfoSync().keys.includes(SHOW_TIP)
		},
		props:{
			tip:{
				type:String,
				default:"点击「添加小程序」，下次访问更便捷",
				required:true				
			},
			duration:{
				type:Number,
				default:5,
				required:false
			}
		},
		methods:{
			hideTip(){
				uni.setStorageSync(SHOW_TIP,true)
				this.showTip = false
			}
		}
	}
</script>
