1.动画的type值

1）@"cube"立方体效果

2）@"suckEffect"收缩效果，如一块布被抽走

3）@"oglFlip"上下翻转效果

4）@"rippleEffect"滴水效果

5）@"pageCurl"向上翻一页

6）@"pageUnCurl"向下翻一页

7）@"rotate"旋转效果

8）@"cameraIrisHollowOpen"

相机镜头打开效果(不支持过渡方向)

9）@"cameraIrisHollowClose"

相机镜头关上效果(不支持过渡方向)

2.当type为@"rotate"(旋转)的时候,它也有几个对应的subtype,分别为:

1）90cw逆时针旋转90°

2）90ccw顺时针旋转90°

3）180cw逆时针旋转180°

4）180ccw顺时针旋转180°
