牛逼的loading加载效果

牛逼的loading加载效果

?

介绍：

AnimatedCircleLoadingView一个不错的loading加载效果，自定义AnimatedCircleLoadingView设置startDeterminate()
方法启动loading页面动画setPercent（）设置loading进度 ，重置resetLoading（）,等几个重要方法实现。
本例子来自：http://www.itlanbao.com/code/20151208/10000/100681.html
本例子主要由TopCircleBorderView ，FinishedOkView，FinishedFailureView等实现。

主要代码实现类：
