IOS QuartzCore核心动画框架
IOS QuartzCore核心动画框架
- 使用核心动画需要引入的框架:#import
- CALayer: CoreAnimation
- CALayer就是UIView上的图层,很多的CALayer组成了UIView。
- CALayer与UIView是两个完全不同的类
- UIView动画就是简单动画,可以实现改变,偏移,形变,翻转,旋转,翻页
- QuartzCore.framework:
- CAAnimation:
- CAAnimationGroup: 并行动画
- CATransition:
- CAPropertyAnimation: 属性动画
- CABasicAnimation:
- CAKeyframeAnimation:
-
