iOS开源绘图应用程序源代码
问题描述：
在哪里可以找到适用于iOS的基于Quartz的绘图应用程序的示例源代码？
由于iPhone / iPad周围有各种各样的绘图应用程序，我认为必须有某种开源项目用于绘图。但是，搜索没有带来任何结果。
Where can I find a sample source code of a Quartz-based drawing application for iOS ? As there are tons of various drawing applications for iPhone/iPad around, I assume there must be some kind of an open source project for drawing. However, the search brings nothing.

您可以使用 UIBezierPath 时，检查出这个教程和示例代码。这实际上非常简单。
You can use UIBezierPath, check out this tutorial and sample code. It's actually surprisingly easy.
