我把源码上传到了GitHub，大家下载之后可以直接使用，非常方便。地址在这 https://github.com/CoderPaulYin/YXProgressView.git

基本的使用举例：

 _myProgressView = [[YXProgressView alloc] initWithFrame:CGRectMake(0, 100, 80, 80)];
    _myProgressView.centerX = self.view.centerX;
    _myProgressView.actionLineColor = [UIColor greenColor];//设置进度条的填充颜色，也可以设置其他颜色
    [self.view addSubview:_myProgressView];

然后在其他需要更新进度的地方：

- (void)sliderValueChanged:(UISlider *)sender{
    NSLog(@"%f",sender.value);
    _myProgressView.progress = sender.value;
}
