/**
 //以下是基本的四种效果
 kCATransitionPush 推入效果
 kCATransitionMoveIn 移入效果
 kCATransitionReveal 截开效果
 kCATransitionFade 渐入渐出效果
 
 //以下API效果可以安全使用
 cube 方块
 suckEffect 三角
 rippleEffect 水波抖动
 pageCurl 上翻页
 pageUnCurl 下翻页
 oglFlip 上下翻转
 cameraIrisHollowOpen 镜头快门开
 cameraIrisHollowClose 镜头快门开
 
 
// 以下API效果请慎用
 spewEffect 新版面在屏幕下方中间位置被释放出来覆盖旧版面.
 genieEffect 旧版面在屏幕左下方或右下方被吸走, 显示出下面的新版面
 unGenieEffect 新版面在屏幕左下方或右下方被释放出来覆盖旧版面.
 twist 版面以水平方向像龙卷风式转出来.
 tubey 版面垂直附有弹性的转出来.
 swirl 旧版面360度旋转并淡出, 显示出新版面.
 charminUltra 旧版面淡出并显示新版面.
 zoomyIn 新版面由小放大走到前面, 旧版面放大由前面消失.
 zoomyOut 新版面屏幕外面缩放出现, 旧版面缩小消失.
 oglApplicationSuspend 像按”home” 按钮的效果.
