希望可以添加详细注释，想好好学学
内存泄露
1.存在严重的内存泄露。ChartView 滑动时存在线性的内存增长。
ZYWCandleChartView.m
CGMutablePathRef redRef = CGPathCreateMutable();
CGMutablePathRef greenRef = CGPathCreateMutable();
这个需要手动释放。
// add
CGPathRelease(redRef);
CGPathRelease(greenRef);
2.浏览了代码，思路是在scrollview上放置ChartView。
这样做是有问题的，数据不断增长，ChartView的宽度可以无限变大。
3.可以只绘制当前界面需要显示的K线，减少不必要的开销。
