*******************************************************
type:动画类型(比如：滴水效果，翻转效果...)
-------------------------------------------------------
fade kCATransitionFade 交叉淡化过渡
moveIn kCATransitionMoveIn 新视图移到旧视图上面
push kCATransitionPush 新视图把旧视图推出去
reveal kCATransitionReveal 将旧视图移开,显示下面的新视图
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 上下左右翻转效果
rotate 旋转效果
cameraIrisHollowClose 相机镜头关上效果(不支持过渡方向)
cameraIrisHollowOpen 相机镜头打开效果(不支持过渡方向)
*******************************************************
subtype: 动画方向(比如说是从左边进入，还是从右边进入...)
------------------------------------------------------
kCATransitionFromRight;
kCATransitionFromLeft;
kCATransitionFromTop;
kCATransitionFromBottom;
当 type 为@"rotate"(旋转)的时候,它也有几个对应的 subtype,分别为:
90cw 逆时针旋转 90°
90ccw 顺时针旋转 90°
180cw 逆时针旋转 180°
180ccw 顺时针旋转 180°
