UIViewAnimation动画与CATransition类动画

CATransition

CATransition is an Objective-C wrapper for creating view transitions. As of 3.1.2, there are 11 types of transitions. 4 of them are SDK-compatible, but are the most boring ones. The following shows all 11 types of transition from picture "A" to "B" at 40%. The subtypes, if any, is "fromLeft".

cameraIris

cube

fade (kCATransitionFade)

moveIn (kCATransitionMoveIn)

oglFlip

pageCurl

pageUnCurl

push (kCATransitionPush)

reveal (kCATransitionReveal)

rippleEffect

suckEffect

subtype and filter

Main article: CAFilter

Many transitions have are further divided into several discrete subtypes. They often control the movement direction of the animation.

Some transitions accept addition arguments through the filter property, for example, you can set the location of suckEffect using

...CAFilter* filter = [CAFilter filterWithName:@"suckEffect"];[filter setValue:[NSValue valueWithCGPoint:CGPointMake(160, 240)] forKey:@"inputPosition"];transition.filter = filter;...

Transition	Subtypes	Accepted parameters
moveIn push reveal	fromLeft, fromRight, fromBottom, fromTop	-
pageCurl, pageUnCurl	fromLeft, fromRight, fromTop, fromBottom	`float inputColor[];`
cube alignedCube	fromLeft, fromRight, fromTop, fromBottom	`float inputAmount;` (perspective)
flip alignedFlip oglFlip	fromLeft, fromRight, fromTop, fromBottom	`float inputAmount;`
cameraIris	-	`CGPoint inputPosition;`
rippleEffect	-	-
rotate	90cw, 90ccw, 180cw, 180ccw	-
suckEffect	-	`CGPoint inputPosition;`

UIViewAnimation动画与Core Animation的CATransition类动画

1.使用UIView类函数实现:

//UIViewAnimationTransitionFlipFromLeft, 向左转动
//UIViewAnimationTransitionFlipFromRight, 向右转动
//UIViewAnimationTransitionCurlUp, 向上翻动
//UIViewAnimationTransitionCurlDown, 向下翻动

[UIView beginAnimations:@"animationID" context:nil];
[UIView setAnimationDuration:0.5f]; //动画时长
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationTransition: UIViewAnimationTransitionFlipFromLeft forView:self.view cache:YES]; //给视图添加过渡效果
//在这里写你的代码.
[UIView commitAnimations]; //提交动画

2.使用CATransition对象来实现:

CATransition比较强大，一般可以使用CATransition模拟UIView的动画。

CATransition *animation = [CATransition animation];
animation.delegate = self;
animation.duration = 0.5f; //动画时长
animation.timingFunction = UIViewAnimationCurveEaseInOut;
animation.fillMode = kCAFillModeForwards;
animation.type = @”cube”; //过度效果
animation.subtype = @”formLeft”; //过渡方向
animation.startProgress = 0.0 //动画开始起点(在整体动画的百分比)
animation.endProgress = 1.0; //动画停止终点(在整体动画的百分比)
animation.removedOnCompletion = NO;
[self.view.layer addAnimation:animation forKey:@"animation"];

实现iPhone漂亮的动画效果主要有两种方法：

　　一种是UIView层面的，

　　一种是使用CATransition进行更低层次的控制，

　　第一种是UIView，UIView方式可能在低层也是使用CATransition进行了封装，它只能用于一些简单的、常用的效果展现，这里写一个常用的示例代码，供大家参考。

　　Cpp代码

　　[UIView beginAnimations:@"Curl"context:nil];//动画开始

　　[UIView setAnimationDuration:0.75];

　　[UIView setAnimationDelegate:self];

　　[UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:myview cache:YES];

　　[myview removeFromSuperview];

　　[UIView commitAnimations];

　　第二种方式相对复杂一些，但如果更好的进行控制，还是使用这种方法吧，

　　基本使用方法可以看一下如下例子：

　　Cpp代码

　　CATransition *animation = [CATransition animation];

　　[animation setDuration:1.25f];

　　[animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseIn]];

　　[animation setType:kCATransitionReveal];

　　[animation setSubtype: kCATransitionFromBottom];

　　[self.view.layer addAnimation:animation forKey:@"Reveal"];

　　这里使用了setType与setSubtype组合，这使用个比较保险，因为他的参数就是官方API里定义的，他们的参数说明可以参考如下：

　　[animation setType:@"suckEffect"];

　　这里的suckEffect就是效果名称，可以用的效果主要有：

　　Cpp代码

　　pageCurl 向上翻一页

　　pageUnCurl 向下翻一页

　　rippleEffect 滴水效果

　　suckEffect 收缩效果，如一块布被抽走

　　cube 立方体效果

　　oglFlip 上下翻转效果

iphone中CABasicAnimation和UIView动画的区别[转]

关于UIView动画：

[UIView beginAnimations:@"zoom out"
context:nil];
[UIView setAnimationDuration:1.f];
[UIView setAnimationCurve:UIViewAnimationCurveEase
Out];
cover.transform
=
CGAffineTransformMakeSca
le(9.25,7.05);
cover.center
=
CGPointMake(430,
512);
[UIView
commitAnimations]

UIView动画是应用在一个view上面的。

关于CABasicAnimation动画：

-
(CAAnimation
*)animationMove:(CGPoint)rootCenter
{
CABasicAnimation
*animationMove
=
[CABasicAnimation animationWithKeyPath:@"position"];
animationMove.duration
=
1;
animationMove.autoreverses
=
NO;
// animationMove.delegate = self;
animationMove.removedOnCompletion
=
NO;
animationMove.fillMode
=
kCAFillModeForwards;
animationMove.fromValue
=
[NSValue valueWithCGPoint:self.oldCoverCenter];
animationMove.toValue
=[NSValue valueWithCGPoint:rootCenter];
return
animationMove;
}

CABasicAnimation动画是应用在一个layer上面的。

注：
1，把一个p_w_picpath放在一个view的layer上来放大的时候，如果用UIView来做，图片不会太多的失真和闪烁的效果，但是用CABasicAnimation来做失真和闪烁现象会很严重，效果很不好。
2，做动画的叠加效果很简单，只要把各自的动画放在一起就可以了。请看这个效果：一本书边移动到屏幕中间，边放大，边打开封面的效果。
