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 = [UIImageViewalloc];

[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]; }]; 

                 }];
