IOS中各种动画特效的实现

第一类动画特效：

这类特效有四种，在UIView中就可以实现，分别为CurlDown，CurlUp，FilpFromLeft，FilpFromRight。在视图切换之前设置UIView，如下：

[UIView
beginAnimations:@"Animation" context:nil];

[UIView setAnimationDuration:0.5];//设置动画持续时间；

[UIView setAnimationDelegate:self];

[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];

接下来设置动画特效，有四种特效可供选择：

[UIView
setAnimationTransition:UIViewAnimationTransitionCurlDown
forView:self.view cache:YES];

[UIView
setAnimationTransition:UIViewAnimationTransitionCurlUp
forView:self.view cache:YES];

[UIView
setAnimationTransition:UIViewAnimationTransitionFilpFromLeft forView:self.view
cache:YES];

[UIView
setAnimationTransition:UIViewAnimationTransitionFilpFromRight forView:self.view
cache:YES];

之后就可以切换view了，最后执行动画：

[UIView commitAnimations];

第二类动画特效：

这类动画特效需要用到QuartzCore.framework，单击工程，点击Build
Phases，找到Link Binary With
Libraries，点击下面的+号，找到QuartzCore.framework添加即可。

同样，在view切换之前需要做一些设置：

CATransition
*animation = [CATransition
animation]; //声明动画对象；

animation.delegate = self;

animation.duration = kDuration;//设置动画持续时间；

animation.timingFunction = UIViewAnimationCurveEaseInOut;

然后就可以选择动画类型，大概有十二种动画：

animation.type = kCATransitionFade;

animation.type = kCATransitionPush;

animation.type = kCATransitionReveal;

animation.type = kCATransitionMoveIn;

animation.type = @"cube";

animation.type = @"suckEffect";

animation.type = @"oglFlip";

animation.type = @"rippleEffect";

animation.type = @"pageCurl";

animation.type = @"pageUnCurl";

animation.type = @"cameraIrisHollowOpen";

animation.type = @"cameraIrisHollowClose";

任选其中一种。同时也可以设置animation的subtype，用以设置动画运行的方向，如：

animation.subtype
= kCATransitionFromLeft;

animation.subtype
= kCATransitionFromBottom;

animation.subtype
= kCATransitionFromRight;

animation.subtype
= kCATransitionFromTop;

之后是切换view，最后还要添加一句代码：

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