ios uiview 动画


[UIView beginAnimations:@"flipping view" context:nil]
[UIView setAnimationDuration:1];
[UIView setAnimationCurve:UIViewAnimationCurveEaseIn];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.view.superview cache:YES];
//你的动作,比如删除某个东西
//eg. [self.view removeFromSuperview];
[UIView commitAnimations];



 



 



在一个UIView对象中有以下的动画化属性:
frame - 你可以使用这个来动画的改变视图的尺寸和位置
bounds - 使用这个可以动画的改变视图的尺寸
center - 使用这个可以动画的改变视图的位置
transform - 使用这个可以翻转或者放缩视图
alpha - 使用这个可以改变视图的透明度
backgroundColor - 使用这个可以改变视图的背景颜色
contentStretch - 使用这个可以改变视图内容如何拉伸 



 



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]; }];

}];
