苹果真机调试swiper里嵌套scroll-view，在scroll-view图层上添加一个绝对定位元素，当swiper滑动时，绝对定位元素别scroll-view覆盖了

<view>
  <swiper>
    <swiper-item class="swiper">
      <view class="swiper-item-wrapper">
        <view class="swiper-item-pos"></view>
        <scroll-view scroll-y style="height: 500rpx;" >
          <view class="scroll-view-item">1</view>
          <view class="scroll-view-item">2</view>
          <view class="scroll-view-item">3</view>
          <view class="scroll-view-item">4</view>
          <view class="scroll-view-item">6</view>
          <view class="scroll-view-item">7</view>
        </scroll-view>
      </view>
    </swiper-item>
    <swiper-item>
      <view class="swiper-item-wrapper">
        <view class="swiper-item-pos"></view>
        <scroll-view scroll-y style="height: 500rpx;" >
          <view class="scroll-view-item">one</view>
          <view class="scroll-view-item">two</view>
          <view class="scroll-view-item">three</view>
          <view class="scroll-view-item">four</view>
          <view class="scroll-view-item">five</view>
          <view class="scroll-view-item">six</view>
          <view class="scroll-view-item">seven</view>
        </scroll-view>
      </view>
    </swiper-item>
    <swiper-item>
      <view class="swiper-item-wrapper">
        <view class="swiper-item-pos"></view>
          <scroll-view scroll-y style="height: 500rpx;" >
            <view class="scroll-view-item">一</view>
            <view class="scroll-view-item">二</view>
            <view class="scroll-view-item">三</view>

            <view class="scroll-view-item">七</view>
          </scroll-view>
        </view>
    </swiper-item>
  </swiper>
</view>
