ios 动画效果

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type 11 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) transition 3 { 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 *) imageName 3 { 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;
