小程序总是意外退出，小程序中使用swiper

<!--用户卡片轮播图开始-->

<swiper vertical="true" current="{{ currentOutSide }}" bindchange="changeSwiper">

<block>

<swiper-item wx:key="unique" wx:for="{{ recommendList }}" wx:for-index="idx" wx:for-item="item">

<swiper class="swiper-box {{ item.images.length > 1?'':'hideDot' }}" current="{{ currentPic }}" indicator-dots="true">

<block>

<swiper-item class="swiper-box-item" wx:key="unique" wx:for="{{ item.images }}" wx:for-index="img-idx" wx:for-item="imgItem">

<image mode='aspectFill' src='{{ imgItem.imageUrl+"?imageView2/1/w/750/h/1334/q/100 " }}'></image>

</swiper-item>

</block>

</swiper>

</swiper-item>

</block>

</swiper>
