CATransition 转场动画 可以切换视图、视图控制器
type 转场动画的 动画效果
subtype 转场动画 动画的方向
kCATransitionFade 交叉淡化过渡
kCATransitionMoveIn 新视图移到旧视图上面
kCATransitionPush 新视图把旧视图推出去
kCATransitionReveal 将旧视图移开,显示下面的新视图
私有api 不建议使用 苹果不提供维护 并且有可能app审核不通过
pageCurl 向上翻一页
pageUnCurl 向下翻一页
rippleEffect 滴水效果
suckEffect 收缩效果 如一块布被抽走
cube 立方体效果
oglFlip 上下翻转效果
*/
/* 过渡效果
fade //交叉淡化过渡(不支持过渡方向) kCATransitionFade
push //新视图把旧视图推出去 kCATransitionPush
moveIn //新视图移到旧视图上面 kCATransitionMoveIn
reveal //将旧视图移开,显示下面的新视图 kCATransitionReveal
cube //立方体翻滚效果
oglFlip //上下左右翻转效果
suckEffect //收缩效果，如一块布被抽走(不支持过渡方向)
rippleEffect //滴水效果(不支持过渡方向)
pageCurl //向上翻页效果
pageUnCurl //向下翻页效果
cameraIrisHollowOpen //相机镜头打开效果(不支持过渡方向)
cameraIrisHollowClose //相机镜头关上效果(不支持过渡方向)
*/
/* 过渡方向
