 /*
  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。
