安装方法

npm i --save react-native-circular-progress

IOS需要手动Link下ReactART，用Xcode打开项目，添加ART.xcodeproj到Libraries中，然后在Link Binary With Libraries中添加libART.a。如下图所示：

使用示例

import { AnimatedCircularProgress } from 'react-native-circular-progress';

 console.log('onAnimationComplete')}
  backgroundColor="#3d5875" />

API说明

• size – width and height of the circle（圆形的宽度和高度）
• width - thickness of the lines（圆形线的宽度）
• backgroundWidth - thickness of the background line（背景线的宽度）
• fill - current, percentage fill (from 0 to 100)（进度值）
• prefill - percentage fill before the animation (from 0 to 100)（预先设置的进度值）
• tintColor - color of a progress line（圆形的线的颜色）
• backgroundColor - color of a background for progress line. Use 'transparent' to hide(背景线的颜色）
• rotation - by default, progress starts from the angle = 90⦝, you can change it by setting value from -360 to 360(旋转度数)
• tension - the tension value for the spring animation (see here)
• friction - the friction value for the spring animation (see here)
• linecap - the shape to be used at the ends of the circle. Possible values: butt (default), round or square. (see here)
• children(fill) - you can pass function as a child to receive current fill
• onAnimationComplete - you can pass a callback function that will be invoked when animation is complete. (see here)(动画结束时的事件)
• onLinearAnimationComplete - you can pass a callback function that will be invoked when linear animation is complete. (see here)

特别说明

在react-native 0.50.4版本中，backgroundColor设置transparent时会报错。暂时没找到原因。
