CATransition类实现层的转场动画。你可以从一组预定义的转换或者通过提供定制的CIFilter实例来指定转场效果。
//定义个转场动画 CATransition *animation = [CATransition animation]; //转场动画持续时间 animation.duration = 0.2f; //计时函数,从头到尾的流畅度??? animation.timingFunction=UIViewAnimationCurveEaseInOut; //转场动画类型 animation.type = kCATransitionReveal; //转场动画将去的方向 animation.subtype = kCATransitionFromBottom; //动画时你需要的实现 self.tabBarController.tabBar.hidden = YES; //添加动画 (转场动画是添加在层上的动画) [self.tabBarController.tabBar.layer addAnimation:animation forKey:@"animation"];
说明:
duration:动画持续的时长。
timingFunction:没明白(谁明白的说明一下吧)
type:转场动画的类型。如果在一个自定义的转场动画中指定的过滤器属性,此属性将被忽略。
type共有四种类型:
NSString * const kCATransitionFade;//逐渐消失 NSString * const kCATransitionMoveIn;//移入 NSString * const kCATransitionPush;//平移(暂且这么称呼吧) NSString * const kCATransitionReveal;//显露
默认类型为kCATransitionFade。
subtype:转场动画将要去往的方向。
subtpye有四种类型:
NSString * const kCATransitionFromRight; NSString * const kCATransitionFromLeft; NSString * const kCATransitionFromTop; NSString * const kCATransitionFromBottom;默认方向是nil。
[self.tabBarController.tabBar.layer addAnimation:animation forKey:@"animation"];
以下几种转场动画调用的苹果的私有API,注意咯,小心用了之后被苹果打回来。
switch (btn.tag) { case 0: animation.type = @"cube";//---立方体 break; case 1: animation.type = @"suckEffect";//103 吸走的效果 break; case 2://前后翻转效果 animation.type = @"oglFlip";//When subType is "fromLeft" or "fromRight", it's the official one. break; case 3: animation.type = @"rippleEffect";//110波纹效果 break; case 4: animation.type = @"pageCurl";//101翻页起来 break; case 5: animation.type = @"pageUnCurl";//102翻页下来 break; case 6: animation.type = @"cameraIrisHollowOpen ";//107//镜头开 break; case 7: animation.type = @"cameraIrisHollowClose ";//106镜头关 break; default: break; }
