uniapp上下滑屏切换支持视频和图片轮播实现，类似抖音效果

实现方法：

swiper中嵌套swiper，通过给swiper设置自定义属性，判断数据类型是图片还是视频，从而控制视频自动播放和图片轮播效果:

代码：

<template>
	<swiper class="swiper" :vertical="true" @change="change" @touchstart="touchStart" @touchend="touchEnd">
		<block v-for="item of videoList" :key="item.id">
			<swiper-item ref="swiperItem" data-type="video" class="swiper-item" v-if="item.type === 'video'">
				<videoPlayer :video="item" ref="player"></videoPlayer>
			</swiper-item>
			<swiper-item ref="swiperItem" data-type="img" v-else>
				<swiper :style="{height:screenHeight+'px'}" class="img-boxs" circular :indicator-dots="true"
					:autoplay="true" :current="currentImgIndex" @change="changeswiper">
					<swiper-item v-for="(item, index) in item.imgList" :key="index">
						<image :src="item" mode="scaleToFill" class="swiper-img" :indicator-dots="true"></image>
					</swiper-item>
				</swiper>
			</swiper-item>
		</block>
	</swiper>
</template>
