在ios开发中，什么是 opengl、quartz 2d？
OpenGL和Quartz 2D都是用于在iOS设备上进行图形渲染的技术。 OpenGL是一种跨平台的图形编程接口，它允许开发者使用硬件加速的图形渲染引擎来创建复杂的2D和3D图形。OpenGL的主要优点是它的灵活性和高性能，但它也需要开发者具备一定的图形编程知识。 Quartz 2D是iOS平台上的2D图形库，它提供了丰富的API来创建和操作图形，包括绘制线条、矩形、圆形、曲线等基本形状，以及填充颜色、添加阴影和纹理等效果。Quartz 2D的主要优点是它的简单易用和高度集成，开发者可以使用它来快速创建各种2D图形和用户界面元素。 在iOS开发中，开发者通常会根据项目的需求和自己的技能水平来选择使用OpenGL还是Quartz 2D。如果需要创建复杂的3D图形或者需要使用硬件加速，那么可能会选择OpenGL；如果只需要创建简单的2D图形或者需要更高的开发效率，那么可能会选择Quartz 2D。 [2023-11-08 00:43:32 | AI写代码神器 | 212点数解答]
