1.在iOS中核心动画分为几类: 基础动画(CABasicAnimation) 关键帧动画(CAKeyframeAnimation) 动画组(CAAnimationGroup) 转场动画(CATransition) 2.CAAnimation:核心动画的基础类,不能直接使用,负责动画运行时间,速度的控制,本身实现了CAMediaTiming协议 3.CAPropertyAnimation:属性动画也是基类(通过属性进行动画设置,注意是动画属性),不能直接使用. CABasicAnimation:…

1.CALayer简介 CALayer是个与UIView很类似的概念,同样有backgroundColor.frame等相似的属性,我们可以将UIView看做一种特殊的CALayer.但实际上UIView是对CALayer封装,在CALayer的基础上再添加交互功能.UIView的显示必须依赖于CALayer.我们同样可以跟新建view一样新建一个layer,然后添加到某个已有的layer上,同样可以对layer调整大小.位置.透明度等.一般来说,layer可以有两种用途:一是对view相关属性…
