uview ui 1.x ActonSheet项太多，设置滚动

问题：ActionSheet滚动不了。

使用uview ui ：u-action-sheet, 但是item太多，超出屏幕了，查了一下文档，并没有设置滚动的地方。

官方文档：ActionSheet 操作菜单 | uView - 多平台快速开发的UI框架 - uni-app UI框架

解决

只能修改源码了,在v-for遍历外面添加一个滚动视图，即可，其他不变

<template>
	<u-popup mode="bottom" :border-radius="borderRadius" :popup="false" v-model="value" :maskCloseAble="maskCloseAble"
	    length="auto" :safeAreaInsetBottom="safeAreaInsetBottom" @close="popupClose" :z-index="uZIndex">
		<view class="u-tips u-border-bottom" v-if="tips.text" :style="[tipsStyle]">
			{{tips.text}}
		</view>
    <scroll-view scroll-y style="min-height: 100rpx;max-height: 700rpx;">
		<block v-for="(item, index) in list" :key="index">
			<view
				@touchmove.stop.prevent
				@tap="itemClick(index)"
				:style="[itemStyle(index)]"
				class="u-action-sheet-item u-line-1"
				:class="[index < list.length - 1 ? 'u-border-bottom' : '']"
				:hover-stay-time="150"
			>
				<text>{{item.text}}</text>
				<text class="u-action-sheet-item__subtext u-line-1" v-if="item.subText">{{item.subText}}</text>
			</view>
		</block>
    </scroll-view>
		<view class="u-gab" v-if="cancelBtn">
		</view>
		<view @touchmove.stop.prevent class="u-actionsheet-cancel u-action-sheet-item" hover-class="u-hover-class"
		    :hover-stay-time="150" v-if="cancelBtn" @tap="close">{{cancelText}}</view>
	</u-popup>
</template>

效果：控制差不多半屏显示了，不超屏幕了。在电脑上用鼠标滚轮很正常。但是在手机滚动不了。

问题2：手机上触摸滚动不了。

再去看源码，发现包裹着block里的view禁止触摸事件，导致滚动视图滚动不了。把@touchmove.stop.prevent删除即可

最终代码

<template>
	<u-popup mode="bottom" :border-radius="borderRadius" :popup="false" v-model="value" :maskCloseAble="maskCloseAble"
	    length="auto" :safeAreaInsetBottom="safeAreaInsetBottom" @close="popupClose" :z-index="uZIndex">
		<view class="u-tips u-border-bottom" v-if="tips.text" :style="[tipsStyle]">
			{{tips.text}}
		</view>
    <scroll-view scroll-y="true" style="min-height: 100rpx;max-height: 700rpx;">
		<block v-for="(item, index) in list" :key="index">
			<view
				@tap="itemClick(index)"
				:style="[itemStyle(index)]"
				class="u-action-sheet-item u-line-1"
				:class="[index < list.length - 1 ? 'u-border-bottom' : '']"
				:hover-stay-time="150"
			>
				<text>{{item.text}}</text>
				<text class="u-action-sheet-item__subtext u-line-1" v-if="item.subText">{{item.subText}}</text>
			</view>
		</block>
    </scroll-view>
		<view class="u-gab" v-if="cancelBtn">
		</view>
		<view @touchmove.stop.prevent class="u-actionsheet-cancel u-action-sheet-item" hover-class="u-hover-class"
		    :hover-stay-time="150" v-if="cancelBtn" @tap="close">{{cancelText}}</view>
	</u-popup>
