IOS动画效果

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){
                     [UIView animateWithDuration:1.2 animations:^{
                         [firstImageView setAlpha:0];
                         [secondImageView setAlpha:0];} completion:^(BOOL finished){ 
                             [firstImageView removeFromSuperview]; 
                             [secondImageView removeFromSuperview]; }]; 
                 }];
