uniapp之自定义图标库的使用

阿里有个矢量图标库，图标很丰富，我们可以从阿里巴巴矢量图标库中下载需要的图标，下载后会自动生成.ttf文件，然后作为我们的自定义字体图标库。

(1) 搜索几个所需要的图标加入购物车

• demo_index.html文件：点击该文件打开网页，可查看字体图标对应的Unicode、Font class和Symble，即对应三种引用方式。网页信息如下：

  Font class.png
  Symble.png

• iconfont.css文件(层叠样式表文件)

@font-face {font-family: "iconfont";
  src: url('iconfont.eot?t=1585729132276'); /* IE9 */
  src: url('iconfont.eot?t=1585729132276#iefix') format('embedded-opentype'), /* IE6-IE8 */
  url('data:application/x-font-woff2;charset=utf-8;base64,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') format('woff2'),
  url('iconfont.woff?t=1585729132276') format('woff'),
  url('iconfont.ttf?t=1585729132276') format('truetype'), /* chrome, firefox, opera, Safari, Android, iOS 4.2+ */
  url('iconfont.svg?t=1585729132276#iconfont') format('svg'); /* iOS 4.1- */
}

.iconfont {
  font-family: "iconfont" !important;
  font-size: 16px;
  font-style: normal;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
}

.icon-saomiao:before {
  content: "\e639";
}

.icon-zhifubao:before {
  content: "\e689";
}

• iconfont.ttf文件：字体图标库文件，需复制到我们的项目

(4) 将iconfont.ttf文件复制static文件夹下
(5) 新建 iconfont.css 文件，引入iconfont.ttf文件

@font-face {
    font-family: "iconfont";
    font-weight: normal;
    font-style: normal;
    src: url('./static/iconfont.ttf') format('truetype');
}

.iconfont {
  font-family: "iconfont" !important;
  font-size: 16px;
  font-style: normal;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
}

.icon-saomiao:before {
  content: "\e639";
}

.icon-zhifubao:before {
  content: "\e689";
}

(6) 使用自定义字体图标

• index.vue 页面中使用字体图标

<template>
    <view class="content">
        <image class="logo" src="/static/logo.png"></image>
        <view class="text-area">
            <text class="title">{{title}}</text>
            <!-- <text class="iconfont icon-saomiao"></text> -->
            <text class="iconfont icon-zhifubao"></text>
        </view>
    </view>
</template>

<script>
    export default {
        data() {
            return {
                title: 'Hello'
            }
        },
        onLoad() {

        },
        methods: {

        }
    }
</script>

<style>
    .content {
        display: flex;
        flex-direction: column;
        align-items: center;
        justify-content: center;
    }

    .logo {
        height: 200rpx;
        width: 200rpx;
        margin-top: 200rpx;
        margin-left: auto;
        margin-right: auto;
        margin-bottom: 50rpx;
    }

    .text-area {
        display: flex;
        justify-content: center;
    }

    .title {
        font-size: 36rpx;
        color: #8f8f94;
    }
</style>

备注：<text class="icon-zhifubao"></text>会导致图标不能正常显示（H5端显示个方框，App端显示方框里面打叉），原因是缺少iconfont样式。

• App.vue 引入css文件

<script>
    export default {
        onLaunch: function() {
            console.log('App Launch')
        },
        onShow: function() {
            console.log('App Show')
        },
        onHide: function() {
            console.log('App Hide')
        }
    }
</script>

<style>
    /*每个页面公共css */
    @import './common/iconfont.css';
</style>

(7) 页面效果如下
