转载:http://www.cnblogs.com/ludashi/p/4160208.html 一.封装动画方法 1.用CATransition实现动画的封装方法如下,每句代码是何意思,请看注释之。 1 #pragma CATransition动画实现 2 - (void) transitionWithType:(NSString *) type WithSubtype:(NSString *) subtype ForView : (UIView *) view 3 { 4 //创建CATransition对象 5 CATransition *animation = [CATransition animation]; 6 7 //设置运动时间 8 animation.duration = DURATION; 9 10 //设置运动type11 animation.type = type;12 if (subtype != nil) {13 14 //设置子类15 animation.subtype = subtype;16 }17 18 //设置运动速度19 animation.timingFunction = UIViewAnimationOptionCurveEaseInOut;20 21 [view.layer addAnimation:animation forKey:@"animation"];22 } 代码说明: CATransition常用的属性如下: duration:设置动画时间 type:稍后下面会详细的介绍运动类型 subtype:和type匹配使用,指定运动的方向,下面也会详细介绍 timingFunction :动画的运动轨迹,用于变化起点和终点之间的插值计算,形象点说它决定了动画运行的节奏,比如是 均匀变化(相同时间变化量相同)还是先快后慢,先慢后快还是先慢再快再慢. * 动画的开始与结束的快慢,有五个预置分别为(下同): * kCAMediaTimingFunctionLinear 线性,即匀速 * kCAMediaTimingFunctionEaseIn 先慢后快 * kCAMediaTimingFunctionEaseOut 先快后慢 * kCAMediaTimingFunctionEaseInEaseOut 先慢后快再慢 * kCAMediaTimingFunctionDefault 实际效果是动画中间比较快. 2.用UIView的block回调实现动画的代码封装 1 #pragma UIView实现动画2 - (void) animationWithView : (UIView *)view WithAnimationTransition : (UIViewAnimationTransition) transition3 {4 [UIView animateWithDuration:DURATION animations:^{5 [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];6 [UIView setAnimationTransition:transition forView:view cache:YES];7 }];8 } 3.改变View的背景图,便于切换时观察1 #pragma 给View添加背景图2 -(void)addBgImageWithImageName:(NSString *) imageName3 {4 self.view.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:imageName]];5 } 二.调用上面的方法实现我们想要的动画 1.我们在View上添加多个Button,给不同的Button设置不同的Tag值,然后再ViewController中绑定同一个方法,点击不同的button实现不同的页面切换效果。storyBoard上的控件效果如下图所示: 2.下面我们就开始编写点击button要回调的方法 (1).定义枚举来标示按钮所对应的动画类型,代码如下: 1 typedef enum : NSUInteger { 2 Fade = 1, //淡入淡出 3 Push, //推挤 4 Reveal, //揭开 5 MoveIn, //覆盖 6 Cube, //立方体 7 SuckEffect, //吮吸 8 OglFlip, //翻转 9 RippleEffect, //波纹10 PageCurl, //翻页11 PageUnCurl, //反翻页12 CameraIrisHollowOpen, //开镜头13 CameraIrisHollowClose, //关镜头14 CurlDown, //下翻页15 CurlUp, //上翻页16 FlipFromLeft, //左翻转17 FlipFromRight, //右翻转18 19 } AnimationType; (2),获取Button的Tag值:1 UIButton *button = sender;2 AnimationType animationType = button.tag; (3).每次点击button都改变subtype的值,包括上,左,下,右 1 NSString *subtypeString; 2 3 switch (_subtype) { 4 case 0: 5 subtypeString = kCATransitionFromLeft; 6 break; 7 case 1: 8 subtypeString = kCATransitionFromBottom; 9 break;10 case 2:11 subtypeString = kCATransitionFromRight;12 break;13 case 3:14 subtypeString = kCATransitionFromTop;15 break;16 default:17 break;18 }19 _subtype += 1;20 if (_subtype > 3) {21 _subtype = 0;22 } (4),通过switch结合上边的枚举来判断是那个按钮点击的1 switch (animationType)2 {3 //各种Case,此处代码下面会给出 4 } 3.调用我们封装的运动方法,来实现动画效果 (1),淡化效果1 case Fade:2 [self transitionWithType:kCATransitionFade WithSubtype:subtypeString ForView:self.view];3 break;4 (2).Push效果1 case Push:2 [self transitionWithType:kCATransitionPush WithSubtype:subtypeString ForView:self.view];3 break;4 效果如下: (3).揭开效果:1 case Reveal:2 [self transitionWithType:kCATransitionReveal WithSubtype:subtypeString ForView:self.view];3 break; 效果图如下: (4).覆盖效果1 case MoveIn:2 [self transitionWithType:kCATransitionMoveIn WithSubtype:subtypeString ForView:self.view];3 break;4 效果图如下: (5).立方体效果1 case Cube:2 [self transitionWithType:@"cube" WithSubtype:subtypeString ForView:self.view];3 break; 效果如下: (6).吮吸效果1 case SuckEffect:2 [self transitionWithType:@"suckEffect" WithSubtype:subtypeString ForView:self.view];3 break; 效果如下: (7).翻转效果1 case OglFlip:2 [self transitionWithType:@"oglFlip" WithSubtype:subtypeString ForView:self.view];3 break; 图如下: 8.波纹效果1 case RippleEffect:2 [self transitionWithType:@"rippleEffect" WithSubtype:subtypeString ForView:self.view];3 break; (9).翻页和反翻页效果1 case PageCurl:2 [self transitionWithType:@"pageCurl" WithSubtype:subtypeString ForView:self.view];3 break;4 5 case PageUnCurl:6 [self transitionWithType:@"pageUnCurl" WithSubtype:subtypeString ForView:self.view];7 break; (10).相机打开效果1 case CameraIrisHollowOpen:2 [self transitionWithType:@"cameraIrisHollowOpen" WithSubtype:subtypeString ForView:self.view];3 break;4 5 case CameraIrisHollowClose:6 [self transitionWithType:@"cameraIrisHollowClose" WithSubtype:subtypeString ForView:self.view];7 break; (11),调用上面封装的第二个动画方法 1 case CurlDown: 2 [self animationWithView:self.view WithAnimationTransition:UIViewAnimationTransitionCurlDown]; 3 break; 4 5 case CurlUp: 6 [self animationWithView:self.view WithAnimationTransition:UIViewAnimationTransitionCurlUp]; 7 break; 8 9 case FlipFromLeft:10 [self animationWithView:self.view WithAnimationTransition:UIViewAnimationTransitionFlipFromLeft];11 break;12 13 case FlipFromRight:14 [self animationWithView:self.view WithAnimationTransition:UIViewAnimationTransitionFlipFromRight];15 break;
