## 引入
全局引入,在 miniprogram 根目录下的`app.json`中配置,局部引入,在需要引入的页面或组件的`index.json`中配置。
```json
"usingComponents": {
"t-icon": "tdesign-miniprogram/icon/icon"
}
```

### 基础组件图标
{{ base }}
### 自定义组件图标
{{ custom }}
自定义图标用法,下面以 `iconfont` 为例
#### 准备图标文件
文件后缀应为`.wxss`,如下方代码块所示:
```css
@font-face {
font-family: 'icon'; // 使用自定义的字体名称
···
}
.icon {
font-family: 'icon' !important; // 字体名称
···
}
.icon-a-0:before { // icon 图标。注意 FontClass 前缀与 font-family 保持一致
content: '\e64d';
}
```
- 添加所需图标,下载图标。图标库一般会提供 **在线链接** 或者 **下载至本地** 等使用方式。**在线链接** 方式会指向一个 `.css` 文件,可以下载或复制其内容,将其修改成后缀名为 `.wxss` 的文件
-`.wxss` 文件中的 `FontClass/Symbol前缀``Font Family` 两项内容保持一致,如: `FontClass/Symbol` 前缀为 `icon-`,则 `Font Family``icon`
> 注:若是采用 `下载至本地` 方式,需关注 `.css` 和 `.ttf` 文件。由于微信小程序不支持处理 `ttf、woff、eot` 等文件,但支持 `base64`,所以需要将 `.ttf` 文件转换为 `base64` (可借助转换工具,如 [transfonter.org](https://transfonter.org/),会得到一个 `stylesheet.css` 文件),然后将 `.css` 文件中的 `@font-face {}` 内容替换为 `stylesheet.css` 中的 `base64` 内容,最后将 `.css` 文件修改后缀为 `.wxss`
#### 引入自定义图标
- 全局引入:在项目 `app.wxss`,使用 `@import` 引入上述的 `.wxss` 文件
- 局部引入:在 `page` 对应的 `.wxss` 中,使用 `@import` 引入上述的 `.wxss` 文件
#### 自定义图标的使用
`<t-icon>` 组件中的 `prefix` 属性值与前面设置的 `Font Family` 保持一致,即 `prefix="icon"``name` 属性值为自定义图标名称,如图标的 `className``icon-a-1h`,则 `name="a-1h"`
### 图片链接
{{ iconImage }}
### 全部图标
<div style="background: #ecf2fe; display: flex; align-items: center; line-height: 20px; padding: 14px 24px; border-radius: 3px; color: #555a65;margin:16px 0">
<svg fill="none" viewBox="0 0 16 16" width="16px" height="16px" style="margin-right: 5px">
<path fill="#0052d9" d="M8 15A7 7 0 108 1a7 7 0 000 14zM7.4 4h1.2v1.2H7.4V4zm.1 2.5h1V12h-1V6.5z" fillOpacity="0.9"></path>
</svg>
<p style="flex: 1">大部分图标在 1.8.0 版本中新增,如果发现引入组件库后,部分图标无法使用,请检查安装的组件库`tdesign-miniprogram`的版本。支持中文英文搜索,如果觉得可以再增加其他关键词提示,欢迎到 <a href="https://github.com/Tencent/tdesign-icons/blob/develop/packages/view/src/manifest.js" target="_blank" > 图标仓库</a> 提交PR帮我们一起补充。
