ios scroll-view无法滚动 使用uview折叠面板嵌套scroll-view

嵌套之后安卓可以滚动，ios无法滚动

<u-collapse accordion @open='collapseOpen' @change='collapseChange' ref="uCollapse" :value='uCollapseValue'><u-collapse-item :name='index' :title="item.text+' ('+item.num+'张) '" v-for="item,index in voucherCate":key="index"><view class="u-collapse-content" v-if="openList==index":style="{'height':`calc( 100vh - 88rpx - 170rpx - ${voucherCateLength * 82 }rpx  - ${calculateStatusBar})`}"><scroll-view scroll-y="true" class="scroll-view " :enhanced="true" :bounces="false":refresher-enabled='enabled' refresher-default-style='none' @refresherrefresh='refresh'@refresherpulling='pulling' @scroll='scroll' :refresher-triggered='triggered'@refresherrestore='store' @scrolltolower='scrollBottom'><view:style="{background: 'url('+wanhaoCard+') #FFF no-repeat center center',backgroundSize:'100% 100%'}"class="brokers-box-c" v-for="(item,index) in brokersList" :key="index"@click="onBrokers(item,index)"><view class="brokers-box-r justify-between align-center"><view v-if="checked==0" class="go-use justify-center align-center"@click="onBrokers(index)">去使用</view></view></view></scroll-view></view></u-collapse-item></u-collapse>

原因是动态设置scroll-view高度的时候将高度错误

错误代码

:style="{'max-height':`calc( 100vh - 88rpx - 170rpx - ${voucherCateLength * 82 }rpx  - ${calculateStatusBar})`}">

正确ios代码 解决

:style="{'height':`calc( 100vh - 88rpx - 170rpx - ${voucherCateLength * 82 }rpx  - ${calculateStatusBar})`}">

页面跳转失效

报错代码

[Vue warn]: Missing ref owner context. ref cannot be used on hoisted vnodes. A vnode with ref must be created inside the render function.at <Tabbar__pageId=6__pagePath="pages/tabbar/tabbar"__pageQuery={} ...>

找到问题代码

<mine v-if="PageCur==1" ref='mine'></mine>

解决问题 问题的原因是因为vue3的ref如果使用在setup里要声明对应的

<mine v-if="PageCur==1" ></mine>
