各种效果动画操作展示（放大、缩小、旋转、翻转等）

各效果动画主要是对UIView，或UIView的layer进行操作。

动画效果有放大、缩小、旋转、翻转等操作；以及还有私有API的方法，如立方体旋转、相机开或关、抽纸、涟漪等。

1、各种动画效果 
其中除了'fade', `moveIn', `push' , `reveal' ,其他属于似有的API(我是这么认为的,可以点进去看下注释).可以分别使用'kCATransitionFade',
'kCATransitionMoveIn', 'kCATransitionPush', 'kCATransitionReveal'来调用.

 @"cube"                  立方体翻滚效果

 @"moveIn"                新视图移到旧视图上面

 @"reveal"                显露效果(将旧视图移开,显示下面的新视图)

 @"fade"                  交叉淡化过渡(不支持过渡方向)(默认为此效果)

 @"pageCurl"              向上翻一页

 @"pageUnCurl"            向下翻一页

 @"suckEffect"            收缩效果，类似系统最小化窗口时的神奇效果(不支持过渡方向)

 @"rippleEffect"          滴水效果,(不支持过渡方向)

 @"oglFlip"               上下左右翻转效果

 @"rotate"                旋转效果

 @"push"

 @"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)

 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、subType 各种动画方向

 kCATransitionFromRight; 同字面意思(下同)

 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°

 3、timingFunction
用于变化起点和终点之间的插值计算,形象点说它决定了动画运行的节奏,比如是均匀变化(相同时间变化量相同)还是先快后慢,先慢后快还是先慢再快再慢.

 动画的开始与结束的快慢,有五个预置分别为(下同):

 kCAMediaTimingFunctionLinear       
线性,即匀速

 kCAMediaTimingFunctionEaseIn       
先慢后快

 kCAMediaTimingFunctionEaseOut      
先快后慢

 kCAMediaTimingFunctionEaseInEaseOut
先慢后快再慢

 kCAMediaTimingFunctionDefault      
实际效果是动画中间比较快
