/*
 CATransition的type属性

 1.#define定义的常量
     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

 2.用字符串表示
     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

 CATransition比较强大，一般可以使用CATransition模拟UIView的动画。
