IOS QuartzCore核心动画框架

IOS QuartzCore核心动画框架

 

核心动画框架

1. 使用核心动画需要引入的框架：#import 
2. CALayer: CoreAnimation 
3. CALayer就是UIView上的图层，很多的CALayer组成了UIView。
4. CALayer与UIView是两个完全不同的类
5. 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
6. QuartzCore.framework:
7. 1. CAAnimation： 
   2. 1. CAAnimationGroup: 并行动画
      2. CATransition:
      3. CAPropertyAnimation: 属性动画
      4. 1. CABasicAnimation:
         2. CAKeyframeAnimation:
            
            
            

8. // 使用关键帧动画进行旋转

   CAKeyframeAnimation *keyFrame = [CAKeyframeAnimation animationWithKeyPath:@"transform"];

   CATransform3D transform3d1 = CATransform3DMakeRotation(M_PI * 0.0, 0, 0, 1.0f);

   // 设置动画的移入的位置 从左、从右、从上、从下

   // animation.subtype = kCATransitionFromTop;

   // 给animatedView添加动画
