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。
viewplaincopy to clipboardprint?
1.[UIView beginAnimations:@"Curl"context:nil];//动画开始
2.[UIView setAnimationDuration:0.75];
3.[UIView setAnimationDelegate:self];
4.[UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:myview cache:YES];
5.[myview removeFromSuperview];
6.[UIView commitAnimations];
[UIViewbeginAnimations:@"Curl"context:nil];//动画开始[UIView setAnimationDuration:0.75];[UIView setAnimationDelegate:self];[UIViewsetAnimationTransition:UIViewAnimationTransitionCurlUp forView:myviewcache: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：
viewplaincopy to clipboardprint?
1.CATransition *animation = [CATransition animation];
2.[animation setDuration:1.25f];
3.[animation setTimingFunction:[CAMediaTimingFunction
4.functionWithName:kCAMediaTimingFunctionEaseIn]];
5.[animation setType:kCATransitionReveal];
6.[animation setSubtype: kCATransitionFromBottom];
7.[self.view.layer addAnimation:animation forKey:@"Reveal"];
CATransition*animation = [CATransition animation];[animation setDuration:1.25f];[animationsetTimingFunction:[CAMediaTimingFunctionfunctionWithName:kCAMediaTimingFunctionEaseIn]];[animationsetType:kCATransitionReveal];[animation setSubtype:kCATransitionFromBottom];[self.view.layer addAnimation:animationforKey:@"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：
viewplaincopy to clipboardprint?
1.setType:可以返回四种类型：
2.kCATransitionFade淡出
3.kCATransitionMoveIn覆盖原图
4.kCATransitionPush推出
5.kCATransitionReveal底部显出来
6.setSubtype:也可以有四种类型：
7.kCATransitionFromRight；
8.kCATransitionFromLeft(默认值)
9.kCATransitionFromTop；
10. kCATransitionFromBottom
setType:可以返回四种类型：kCATransitionFade淡出kCATransitionMoveIn覆盖原图kCATransitionPush推出kCATransitionReveal底部显出来setSubtype:也可以有四种类型：kCATransitionFromRight；kCATransitionFromLeft(默认值)kCATransitionFromTop；kCATransitionFromBottom
还有一种设置动画类型的方法，不用setSubtype，只用setType
viewplaincopy to clipboardprint?
1.[animation setType:@"suckEffect"];
[animationsetType:@"suckEffect"];
这里的suckEffect就是效果名称，可以用的效果主要有：
viewplaincopy to clipboardprint?
1.pageCurl 向上翻一页
2.pageUnCurl 向下翻一页
3.rippleEffect 滴水效果
4.suckEffect 收缩效果，如一块布被抽走
5.cube 立方体效果
6.oglFlip 上下翻转效果
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
最后再给出一种常用代码供大家参考。
viewplaincopy to clipboardprint?
1.// Curl the image up or down
2.CATransition *animation = [CATransition animation];
3.[animation setDuration:0.35];
4.[animation setTimingFunction:UIViewAnimationCurveEaseInOut];
5.if (!curled){
6.//animation.type = @"mapCurl";
7.animation.type = @"pageCurl";
8.animation.fillMode = kCAFillModeForwards;
9.animation.endProgress = 0.99;
10. } else {
11. //animation.type = @"mapUnCurl";
12. animation.type = @"pageUnCurl";
13. animation.fillMode = kCAFillModeBackwards;
14. animation.startProgress = 0.01;
15. }
16. [animation setRemovedOnCompletion:NO];
17. [view exchangeSubviewAtIndex:0 withSubviewAtIndex:1];
18. [view addAnimation:animation forKey"pageCurlAnimation"];
19. // Disable user interaction where necessary
20. if (!curled) {
21.
22. } else {
23.
24. }
25. curled = !curled;
// Curl the image up or downCATransition *animation =[CATransition animation];[animation setDuration:0.35];[animationsetTimingFunction:UIViewAnimationCurveEaseInOut];if (!curled){//animation.type= @"mapCurl";animation.type =@"pageCurl";animation.fillMode =kCAFillModeForwards;animation.endProgress = 0.99;} else {//animation.type =@"mapUnCurl";animation.type =@"pageUnCurl";animation.fillMode = kCAFillModeBackwards;animation.startProgress= 0.01;}[animation setRemovedOnCompletion:NO];[view exchangeSubviewAtIndex:0withSubviewAtIndex:1];[view addAnimation:animationforKey"pageCurlAnimation"];// Disable user interaction wherenecessaryif (!curled) { } else { }curled = !curled;
