react-native 进度条组件

react-native-progress

安装
npm install react-native-progress --save

这点很重要：将ART.xcodeproj（找到node_modules/react-native/Libraries/ART）添加到Libraries组，并在Build Phases下添加libART.a到Link Binary With Libraries，（打开Xcode，找到Libraries下的ART点击添加新文件，在上面的路径中找到node_modules/react-native/Libraries/ART）

import * as Progress from 'react-native-progress';

<Progress.Bar progress={0.3} width={200} />
<Progress.Pie progress={0.4} size={50} />
<Progress.Circle size={30} indeterminate={true} />
<Progress.CircleSnail color={['red', 'green', 'blue']} />


下面就简单了。
