在开发短视频小程序中，使用Swiper+ Video 的方式实现，目前是保持Swiper中四个swiper-item，在每次滑动时进行替换，默认播放首个视频，滑动暂停上一个，在swiper的chnge绑定的方法中，每次都有判断更新替换视频数据, 在IOS中滑动视频过程中会出现有些视频滑到后不播放，频繁滑动后会出现闪退! IOS机型如下图 [图片] [图片] 监控日志中显示 应该是内存溢出导致的 <view class="wrapper">     <swiper             style="width:{{screenWidth}}px;height:{{screenHeight}}px"             class="video-swiper"             circular="{{circular}}"             easing-function="{{easingFunction}}"             vertical             current="1"             duration="{{duration}}"             bindanimationfinish="animationfinish">         <!-- curQueue 循环会导致video重新插入，objectFit 不可变更 -->         <swiper-item wx:for="{{curQueue}}" wx:key="index">             <view class="shadow"></view>             <video                     style="width:{{screenWidth}}px;height:{{screenHeight}}px"                     miLinToken="{{miLinToken}}"                     id="{{tabType}}video_{{index}}"                     class="video_item"                     loop="{{loop}}"                     enable-play-gesture                     enable-progress-gesture                     show-center-play-btn="{{false}}"                     controls="{{false}}"                     src="{{item.video_url}}"                     data-id="{{item.id}}"                     object-fit="{{item.sp_text ? item.sp_text: 'contain'}}"                     data-index="{{index}}"             >             </video>                         <view class="video_box_fn">                 <view class="vbf_avatar mb32">                     <image src="{{item.logo}}" class="avatar" mode="aspectFill" catch:tap="toHome"                            data-videodata="{{item}}" />                     <image src="../../images/explosive/add@2x.png" wx:if="{{item.is_follow===0}}" class="add_icon"                            catch:tap="addFollow" data-type="1" data-itemindex="{{itemIndex}}" data-videodata="{{item}}" />                     <image src="../../images/explosive/checkedfollow.png" wx:else class="add_icon" catch:tap="addFollow"                            data-type="0" data-itemindex="{{itemIndex}}" data-videodata="{{item}}" />                 </view>                 <view class="vbf_fn mb32">                     <image src="../../images/explosive/like@2x.png" wx:if="{{item.is_zan===0}}" class="fn_icon"                            catch:tap="addLike" data-itemindex="{{itemIndex}}" data-videodata="{{item}}" />                     <image src="../../images/explosive/checked_like@2x.png" wx:else class="fn_icon"  catch:tap="addLike"                            data-itemindex="{{itemIndex}}" data-videodata="{{item}}" />                     <text class="fn_num">{{toUnit.numToUnit(item.sum_zan)}}</text>                 </view>                 <view class="vbf_fn"  catch:tap="openShare" data-itemindex="{{itemIndex}}" data-videodata="{{item}}">                     <image src="../../images/explosive/share@2x.png" class="fn_icon" />                     <text class="fn_num">{{toUnit.numToUnit(item.sum_fen)}}</text>                 </view>             </view>             <!--视频描述-->             <view wx:if="{{!controls}}">                 <view class="video_box_desc">                     <!--产品卡片-->                     <view class="video_box_product" data-videodata="{{item}}"  catch:tap="toDetail">                         <image class="vbp_pic" src="/images/explosive/product.png" mode="aspectFill" />                         <view class="vbp_desc">                             <text class="vbp_desc_name">{{item.tc_name}}</text>                             <text class="vbp_desc_price">¥{{(item.discount_price)}}</text>                         </view>                     </view>                     <view class="video_desc">{{item.video_title}}</view>                 </view>                 <!--店铺地址-->                 <view class="shop_address" catch:tap="toShopHome" data-videodata="{{item}}">                     <image src="/images/explosive/shop@2x.png" class="shop_icon" />                     <text class="shop_name">{{item.shop_name}}（{{item.distance}}）</text>                 </view>             </view>             <view class="bottom_shadow"></view>         </swiper-item>     </swiper>     <!-- 暂停按钮 -->     <view wx:if="{{isShowPauseBtn}}" class="push_btn"  catch:tap="handlePlay" data-itemindex="{{itemIndex}}"           data-videodata="{{item}}">         <image src="/images/explosive/pause.png" class="pause_icon"/>     </view>     <view wx:if="{{isShowLikeIcon}}" class="like-icon"           style="position:absolute; left:{{row-200}}px; top:{{top-200}}px;width:800rpx;height:800rpx;">         <canvas id="like_lottie" type="2d" style="width: 100%;height: 100%;"/>         <!--        <image src="/images/bg/love.png" animation='{{animationMiddleHeaderItem}}' style="width: 100%;height: 100%;" />-->     </view> </view> <wxs module="toUnit">     var numToUnit = function (num) {         var w = num;         if (num >= 10000) {             w = num / 10000;             w = w.toFixed(1);             w = w + 'w';         }         return w;     }     module.exports = {         numToUnit: numToUnit     } </wxs>
