elementui 遇到问题 el-select搜索框在ipad下无法唤出虚拟键盘

<template><el-selectref="select"@focus="clear"@hook:mounted="clear"@visible-change="clear"></el-select>
</template>
<script>export default {methods: {clear(async) {this.$nextTick(() => {if (!async) {// ios 手机有延迟问题setTimeout(() => {const { select } = this.$refsconst input = select.$el.querySelector('.el-input__inner')input.removeAttribute('readonly')}, 200)}})}}}
</script>```
