本文主要是介绍vue vant ui 教程&注意事项，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！
01
vant 插件PullRefresh下拉刷新 会出现滚动就刷新的情况
常见问题:
1.父级容器不存在overflow：hidden
2.当使用Refresh插件时，如果存在当van-refresh组件的父级overfow-y:scorll 的样式时，选中的滚动条为父级元素，此时当body内部容器撑开页面元素时（也就是body存在滚动条时）
解决方式:
1.给父级容器加上overflow:hidden
2.设置van-refresh组件的父级组件的正确高度，使body的高度不会出现滚动条。
.van-pull-refresh {
height: 100vh;
overflow: auto !important;
}
PullRefresh 的内容未填满屏幕时，只有一部分区域可以下拉？默认情况下，下拉区域的高度是和内容高度保持一致的，如果需要让下拉区域始终为全屏，可以给 PullRefresh 设置一个与屏幕大小相等的最小高度：

vant van-icon使用自定义图标
iconfont图标库： https://www.iconfont.cn/
搜索自己喜好的图标 添加入库
点击我的图标库 选择对应的项目 点击确定
点击更新代码
复制css代码到 Vue项目中
引入到项目中的位置 切记打包时 要配置http或https的形式
可以在App.vue 或main.js 我这里是配置在main.js中
vue文件中的使用
<template>
<div id="tabbar">
<!-- 给tabbar route属性 然后给每一项to属性就可以路由跳转了 -->
<van-tabbar route>
<van-tabbar-item icon="home-o" to="/">书架</van-tabbar-item>
<van-tabbar-item to="/bookShop" >
<div class="customTabbarItem">
<!--引入自定义图标-->
<van-icon class="iconfont iconicon_huabanfuben icon_margin"/>
<span>书城</span>
</div>
</van-tabbar-item>
<van-tabbar-item to="/bookClass" >
<div class="customTabbarItem">
<!--引入自定义图标-->
<van-icon class="iconfont iconleimupinleifenleileibie icon_margin"/>
<span>分类</span>
</div>
</van-tabbar-item>
<van-tabbar-item icon="user-o" to="/profile">我的</van-tabbar-item>
</van-tabbar>
</div>
</template>

vant swiper 轮播图圆角滑动变会变成直角然后再回到圆角(iOS)
#template部分

#css部分
.pull-container {
position: relative;
min-height: 100vh;
width: 100%;
overflow-y: auto; //解决IOS 动态变化时 先变直角在变圆角的处理方案
border: none;
.van-hairline--bottom:after {
border-bottom-width: 0;
}
.cu-swipe{
margin: 0.533rem 0.533rem 0 0.533rem; //可以单独改变元素的上，右，下，左边距，也可以一次改变所有的属性。
-webkit-border-radius: 0.267rem 0.267rem 0 0;
-moz-border-radius: 0.267rem 0.267rem 0 0;
overflow-y: auto; //解决IOS 动态变化时 先变直角在变圆角的处理方案
.van-swipe-item {
width: 100%;
height: 4rem;
font-size: 0.533rem;
text-align: center;
transform: translateY(0); //解决IOS 动态变化时 先变直角在变圆角的处理方案
img{
display:block;
vertical-align:top;
width: 100%;
height: 4rem;
}
}
}
}
由于页面内容太多 我只粘贴主要部分不用直接上来就复制粘贴
04
vue vant ui vant-tab 标签页组件样式调整
<van-tabs v-model="active" sticky title-active-color="#144a9e" // 选中的标签文字颜色 color="#144a9e" // 下面那个下划线颜色 @click="tabClick">
改变van-tab边框颜色 在类名前加上深度操作符: /deep/
/deep/.channel-tabs {
.van-tab {
border-right: 1px solid #edeff3;
}
}
改变van-tab 标签:宽高 文字颜色大小, 底部条:宽高 颜色 位置
.van-tabs__nav { //父元素默认底边15px 可以去掉
padding-bottom: 0;
}
.van-tabs__line {
bottom: 8px;
width: 31px !important;
height: 6px;
background-color: #3296fa;
}
