在react-native项目中使用iconfont自定义图标库

1. 安装react-native-vector-icons

yarn add react-native-vector-icons
react-native link

如果没有关联成功的话，可以参考官方文档手动配置一下

2. 将从阿里下载的iconfont.tff文件复制到以下目录

3. 在android/app/build.gradle中添加:

project.ext.vectoricons = [
    iconFontNames: ['iconfont.ttf' ] //添加你需要赋值的字符文件
]

4. 在项目中创建字体配置文件

// DIYIcon.js

import createIconSet from 'react-native-vector-icons/lib/create-icon-set';
import glyphMap from './iconfont.json';

const iconSet = createIconSet(glyphMap, 'DIYIcon', 'iconfont.ttf');   //  'DIYIcon'可自定义名称

export default iconSet;

export const Button = iconSet.Button;
export const TabBarItem = iconSet.TabBarItem;
export const TabBarItemIOS = iconSet.TabBarItemIOS;
export const ToolbarAndroid = iconSet.ToolbarAndroid;
export const getImageSource = iconSet.getImageSource;

　　

// iconfont.json

{
  "glass": 61440,
  "music": 61441,
  "search": 61442,
  "envelope-o": 61443,
  "heart": 61444,
  "star": 61445,
  "star-o": 61446,
  "user": 61447,
  //等等...
}

5. 使用

import DIYIcon from './diyicon/DIYIcon';

...

<DIYIcon name={'glass'} size={'50'} color={'#ed4040'} />
