ios各种动画效果
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]; }];
}];
