最普通动画:
//开始动画[UIView beginAnimations:nil context:nil];//设定动画持续时间[UIView setAnimationDuration:2];//动画的内容frame.origin.x += 150;[img setFrame:frame];//动画结束[UIView commitAnimations];复制代码
连续动画:一个接一个地显示一系列的图像
NSArray *myImages = [NSArray arrayWithObjects:[UIImage imageNamed:@"myImage1.png"],[UIImage imageNamed:@"myImage2.png"],[UIImage imageNamed:@"myImage3.png"],[UIImage imageNamed:@"myImage4.gif"], nil];UIImageView *myAnimatedView = [UIImageView alloc];[myAnimatedView initWithFrame:[self bounds]];myAnimatedView.animationImages = myImages; //animationImages属性返回一个存放动画图片的数组myAnimatedView.animationDuration = 0.25; //浏览整个图片一次所用的时间myAnimatedView.animationRepeatCount = 0; // 0 = loops forever 动画重复次数[myAnimatedView startAnimating];[self addSubview:myAnimatedView];[myAnimatedView release];CATransition Public API动画:CATransition *animation = [CATransition animation];//动画时间 animation.duration = 0.5f;//先慢后快 animation.timingFunction = UIViewAnimationCurveEaseInOut;animation.fillMode = kCAFillModeForwards;//animation.removedOnCompletion = NO;复制代码
各种动画效果
/*kCAFillModeRemoved 这个是默认值,也就是说当动画开始前和动画结束后,动画对layer都没有影响,动画结束后,layer会恢复到之前的状态kCAFillModeForwards 当动画结束后,layer会一直保持着动画最后的状态kCAFillModeBackwards 这个和kCAFillModeForwards是相对的,就是在动画开始前,你只要将动画加入了一个layer,layer便立即进入动画的初始状态并等待动画开始.你可以这样设定测试代码,将一个动画加入一个layer的时候延迟5秒执行.然后就会发现在动画没有开始的时候,只要动画被加入了layer,layer便处于动画初始状态kCAFillModeBoth 理解了上面两个,这个就很好理解了,这个其实就是上面两个的合成.动画加入后开始之前,layer便处于动画初始状态,动画结束后layer保持动画最后的状态.*//*kCATransitionFromRight;kCATransitionFromLeft;kCATransitionFromTop;kCATransitionFromBottom;*///各种组合animation.type = kCATransitionPush;animation.subtype = kCATransitionFromRight;[self.view.layer addAnimation:animation forKey:@"animation"];CATransition Private API动画:animation.type可以设定为以下效果动画效果汇总:/*suckEffect（三角）rippleEffect（水波抖动）pageCurl（上翻页）pageUnCurl（下翻页）oglFlip（上下翻转）cameraIris/cameraIrisHollowOpen/cameraIrisHollowClose （镜头快门，这一组动画是有效果，只是很难看，不建议使用而以下为则黑名单：spewEffect: 新版面在屏幕下方中间位置被释放出来覆盖旧版面.- genieEffect: 旧版面在屏幕左下方或右下方被吸走, 显示出下面的新版面 (阿拉丁灯神?).- unGenieEffect: 新版面在屏幕左下方或右下方被释放出来覆盖旧版面.- twist: 版面以水平方向像龙卷风式转出来.- tubey: 版面垂直附有弹性的转出来.- swirl: 旧版面360度旋转并淡出, 显示出新版面.- charminUltra: 旧版面淡出并显示新版面.- zoomyIn: 新版面由小放大走到前面, 旧版面放大由前面消失.- zoomyOut: 新版面屏幕外面缩放出现, 旧版面缩小消失.- oglApplicationSuspend: 像按"home" 按钮的效果.*/UIView Animations 动画:[UIView beginAnimations:@"animationID" context:nil];[UIView setAnimationDuration:0.5f];[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];[UIView setAnimationRepeatAutoreverses:NO];//以下四种效果/*[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:self.view cache:YES];//oglFlip, fromLeft[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.view cache:YES];//oglFlip, fromRight[UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:self.view cache:YES];[UIView setAnimationTransition:UIViewAnimationTransitionCurlDown forView:self.view cache:YES];*/[self.view exchangeSubviewAtIndex:1 withSubviewAtIndex:0];[UIView commitAnimations];IOS4.0新方法:方法: +(void)animateWithDuration:(NSTimeInterval)duration animations:(void (^)(void))animations;+ (void)animateWithDuration:(NSTimeInterval)duration animations:(void (^)(void))animations completion:(void (^)(BOOL finished))completion; //多一个动画结束后可以执行的操作.//下边是嵌套使用,先变大再消失的动画效果.[UIView animateWithDuration:1.25 animations:^{CGAffineTransform newTransform = CGAffineTransformMakeScale(1.2, 1.2);[firstImageView setTransform:newTransform];[secondImageView setTransform:newTransform];}completion:^(BOOL finished){[UIView animateWithDuration:1.2 animations:^{[firstImageView setAlpha:0];[secondImageView setAlpha:0];} completion:^(BOOL finished){[firstImageView removeFromSuperview];[secondImageView removeFromSuperview]; }];}];复制代码
