reactnative 使用阿里iconfont

用纯JS把iconfont.cn的图标转换成RN组件，不依赖字体，支持多色彩，支持热更新

yarn add react-native-svg
yarn add react-native-iconfont-cli --dev
npx iconfont-init

{
    "symbol_url": "请参考README.md，复制官网提供的JS链接",
    "use_typescript": false,
    "save_dir": "./src/iconfont",
    "trim_icon_prefix": "icon",
    "default_icon_size": 18,
    "local_svgs": "./localSvgs"
}

npx iconfont-rn
