2024-01-30 12:45:35

关键属性：

type 过渡效果

kCATransitionFade 淡出
kCATransitionMoveIn 覆盖原图
kCATransitionPush 推出
kCATransitionReveal 底部显出来

subtype 过渡方向

kCATransitionFromRight；
kCATransitionFromLeft 默认值
kCATransitionFromTop；
kCATransitionFromBottom

代码演示1：不用setSubtype，只用setType

 animation.type=@"pageCurl";

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

代码演示2：setType与setSubtype组合

 CATransition *animation = [CATransition animation];

 animation.delegate = self;

 animation.duration = 1.0f;

 animation.timingFunction = UIViewAnimationCurveEaseInOut;

 animation.type = kCATransitionMoveIn;

 animation.subtype = kCATransitionFromTop;

 [_myView.layer addAnimation:animation forKey:@"myTransition"];
