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];
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; 
//各种动画效果 
/* 
kCATransitionFade; 
kCATransitionMoveIn; 
kCATransitionPush;z 
kCATransitionReveal; 
*/ 
/* 
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){

[secondImageView setAlpha:0];} completion:^(BOOL finished){ 
[firstImageView removeFromSuperview]; 
[secondImageView removeFromSuperview]; }];
