适用于ios和安卓的自定义picker（微信小程序）

平台兼容性

解决使用原生picker选择器，ios和安卓样式不一致的问题

参数介绍

• popHeight(picker的整体高度，必填，单位为vh，本人为新手，有需要的自己可以改源码)
• isDatePicker(用的是年月日选择器还是时分选择)
• kYear(自定义年，不传，默认为当前时间)
• kMonth(自定义月，不传，默认为当前时间)
• kDay(自定义日，不传，默认为当前时间)
• kHour(自定义时，不传，默认为当前时间)
• kMin(自定义分，不传，默认为当前时间)

例子

<template>
    <view class="timePopup" :style="{ height: popHeight + 'vh'}">
        <view class="" v-if="isDatePicker">
            <picker-view :style="{ height: popHeight - 10 + 'vh' }" :indicator-style="indicatorStyle" :value="value" @change="bindChange">
                <picker-view-column style="text-align: center;">
                    <view :style="{ 'line-height': stylePx }" class="item" v-for="(item, index) in years" :key="index">{{ item }}年</view>
