CABasicAnimation核心动画
1、CABasicAnimation类只有三个属性:
1
2
3
4
|
fromValue:开始值
toValue:结束值
Duration:动画的时间
repeatCount:重复次数
|
2、通过animationWithKeyPath键值对的方式设置不同的动画效果

keyPath : 要设置的属性
path : 路径 可用UIBezierPath(设置了path,将忽略values)
duration : 动画时长
repeatCount : 重复次数
calculationMode : 动画计算方式
values:每一个关键帧(设置了path,将忽略values)
removedOnCompletion:执行完之后不删除动画
fillMode:执行完之后保存最新的状态
delegate:代理
