CATransitionDemo ================ 注：其中有些效果调用了CATransition的Private API, 仅供娱乐。 补充：还是有好多小伙伴问那些可以在AppStore中使用，调用私有API的肯定是不行的，而下方有些就调用了私有API。 下方会用到一些私有API, 有些效果在APPStore中是不能使用的，私有API如下： ```Objective-C NSString *const kCATransitionCube = @"cube"; NSString *const kCATransitionSuckEffect = @"suckEffect"; NSString *const kCATransitionOglFlip = @"oglFlip"; NSString *const kCATransitionRippleEffect = @"rippleEffect"; NSString *const kCATransitionPageCurl = @"pageCurl"; NSString *const kCATransitionPageUnCurl = @"pageUnCurl"; NSString *const kCATransitionCameraIrisHollowOpen = @"cameraIrisHollowOpen"; NSString *const kCATransitionCameraIrisHollowClose = @"cameraIrisHollowClose"; ``` 而下方这些可以放心使用： ```Objective-C // CAAnimation.h /* Common transition types. */ CA_EXTERN NSString * const kCATransitionFade __OSX_AVAILABLE_STARTING (__MAC_10_5, __IPHONE_2_0); CA_EXTERN NSString * const kCATransitionMoveIn __OSX_AVAILABLE_STARTING (__MAC_10_5, __IPHONE_2_0); CA_EXTERN NSString * const kCATransitionPush __OSX_AVAILABLE_STARTING (__MAC_10_5, __IPHONE_2_0); CA_EXTERN NSString * const kCATransitionReveal __OSX_AVAILABLE_STARTING (__MAC_10_5, __IPHONE_2_0); ``` 今天主要用到的动画类是CALayer下的CATransition至于各种动画类中如何继承的在这也不做赘述，网上的资料是一抓一大把。好废话少说切入今天的正题。 ### 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。 ```Objective-C #pragma CATransition动画实现 - (void) transitionWithType:(NSString *) type WithSubtype:(NSString *) subtype ForView : (UIView *) view { //创建CATransition对象 CATransition *animation = [CATransition animation]; //设置运动时间 animation.duration = DURATION; //设置运动type animation.type = type; if (subtype != nil) { //设置子类 animation.subtype = subtype; } //设置运动速度 animation.timingFunction = UIViewAnimationOptionCurveEaseInOut; [view.layer addAnimation:animation forKey:@"animation"]; } ``` 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　 ```Objective-C #pragma UIView实现动画 - (void) animationWithView : (UIView *)view WithAnimationTransition : (UIViewAnimationTransition) transition { [UIView animateWithDuration:DURATION animations:^{ [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut]; [UIView setAnimationTransition:transition forView:view cache:YES]; }]; } ``` #### 3.改变View的背景图，便于切换时观察 ```Objective-C #pragma 给View添加背景图 -(void)addBgImageWithImageName:(NSString *) imageName { self.view.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:imageName]]; } ``` ## 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： ```Objective-C typedef enum : NSUInteger { Fade = 1, //淡入淡出 Push, //推挤 Reveal, //揭开 MoveIn, //覆盖 Cube, //立方体 SuckEffect, //吮吸 OglFlip, //翻转 RippleEffect, //波纹 PageCurl, //翻页 PageUnCurl, //反翻页 CameraIrisHollowOpen, //开镜头 CameraIrisHollowClose, //关镜头 CurlDown, //下翻页 CurlUp, //上翻页 FlipFromLeft, //左翻转 FlipFromRight, //右翻转 } AnimationType; ``` (2),获取Button的Tag值： ```Objective-C UIButton *button = sender; AnimationType animationType = button.tag; ``` (3).每次点击button都改变subtype的值，包括上,左,下,右 ```Objective-C NSString *subtypeString; switch (_subtype) { case 0: subtypeString = kCATransitionFromLeft; break; case 1: subtypeString = kCATransitionFromBottom; break; case 2: subtypeString = kCATransitionFromRight; break; case 3: subtypeString = kCATransitionFromTop; break; default: break; } _subtype += 1; if (_subtype > 3) { _subtype = 0; } ``` (4),通过switch结合上边的枚举来判断是那个按钮点击的 ```Objective-C switch (animationType) { //各种Case,此处代码下面会给出 } ``` #### 3.调用我们封装的运动方法，来实现动画效果 (1),淡化效果 ```Objective-C case Fade: [self transitionWithType:kCATransitionFade WithSubtype:subtypeString ForView:self.view]; break; ``` (2) PUSH效果 ```Objective-C case Push: [self transitionWithType:kCATransitionPush WithSubtype:subtypeString ForView:self.view]; break; ```  (3)、揭开效果 ```Objective-C case Reveal: [self transitionWithType:kCATransitionReveal WithSubtype:subtypeString ForView:self.view]; break; ```  (4)、覆盖效果 ```Objective-C case MoveIn: [self transitionWithType:kCATransitionMoveIn WithSubtype:subtypeString ForView:self.view]; break; ```  (5)、立方体切换 ```Objective-C case Cube: [self transitionWithType:@"cube" WithSubtype:subtypeString ForView:self.view]; break; ```  (6)、吮吸效果 ```Objective-C case SuckEffect: [self transitionWithType:@"suckEffect" WithSubtype:subtypeString ForView:self.view]; break; ```  (7)、翻转效果 ```Objective-C case OglFlip: [self transitionWithType:@"oglFlip" WithSubtype:subtypeString ForView:self.view]; break; ```  (8)、波纹效果 ```Objective-C case RippleEffect: [self transitionWithType:@"rippleEffect" WithSubtype:subtypeString ForView:self.view]; break; ```  (9)、翻页效果 ```Objective-C case PageCurl: [self transitionWithType:@"pageCurl" WithSubtype:subtypeString ForView:self.view]; break; case PageUnCurl: [self transitionWithType:@"pageUnCurl" WithSubtype:subtypeString ForView:self.view]; break; ```  (10)、相机打开效果 ```Objective-C case CameraIrisHollowOpen: [self transitionWithType:@"cameraIrisHollowOpen" WithSubtype:subtypeString ForView:self.view]; break; case CameraIrisHollowClose: [self transitionWithType:@"cameraIrisHollowClose" WithSubtype:subtypeString ForView:self.view]; break; ```  (11),调用上面封装的第二个动画方法 ```Objective-C case CurlDown: [self animationWithView:self.view WithAnimationTransition:UIViewAnimationTransitionCurlDown]; break; case CurlUp: [self animationWithView:self.view WithAnimationTransition:UIViewAnimationTransitionCurlUp]; break; case FlipFromLeft: [self animationWithView:self.view WithAnimationTransition:UIViewAnimationTransitionFlipFromLeft]; break; case FlipFromRight: [self animationWithView:self.view WithAnimationTransition:UIViewAnimationTransitionFlipFromRight]; break; ```
