iOS开发中常用的各种动画、页面切面效果
这篇文章主要介绍了iOS开发中常用的各种动画、页面切面效果的相关资料,需要的朋友可以参考下
今天主要用到的动画类是CALayer下的CATransition至于各种动画类中如何继承的在这也不做赘述，网上的资料是一抓一大把。好废话少说切入今天的正题。
一.封装动画方法
1.用CATransition实现动画的封装方法如下，每句代码是何意思，请看注释之。

17 #pragmaCATransition动画实现
-(void)transitionWithType:(NSString)typeWithSubtype:(NSString)subtypeForView:(UIView)view
{
//创建CATransition对象
CATransitionanimation=[CATransitionanimation];
//设置运动时间
animation.duration=DURATION;
//设置运动type
animation.type=type;
if(subtype!=nil){
//设置子类
animation.subtype=subtype;
}
//设置运动速度
animation.timingFunction=UIViewAnimationOptionCurveEaseInOut;
[view.layeraddAnimation:animationforKey:@"animation"];
} 代码说明：
CATransition常用的属性如下：
duration:设置动画时间
type:稍后下面会详细的介绍运动类型
subtype:和type匹配使用，指定运动的方向，下面也会详细介绍
timingFunction：动画的运动轨迹，用于变化起点和终点之间的插值计算,形象点说它决定了动画运行的节奏,比如是
均匀变化(相同时间变化量相同)还是先快后慢,先慢后快还是先慢再快再慢.
动画的开始与结束的快慢,有五个预置分别为(下同):
kCAMediaTimingFunctionLinear线性,即匀速
kCAMediaTimingFunctionEaseIn先慢后快
kCAMediaTimingFunctionEaseOut先快后慢
kCAMediaTimingFunctionEaseInEaseOut先慢后快再慢
kCAMediaTimingFunctionDefault实际效果是动画中间比较快.
2.用UIView的block回调实现动画的代码封装

8 #pragmaUIView实现动画
-(void)animationWithView:(UIView)viewWithAnimationTransition:(UIViewAnimationTransition)transition
{
[UIViewanimateWithDuration:DURATIONanimations:^{
[UIViewsetAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIViewsetAnimationTransition:transitionforView:viewcache:YES];
}];
} 3.改变View的背景图，便于切换时观察

5 #pragma给View添加背景图
-(void)addBgImageWithImageName:(NSString)imageName
{
self.view.backgroundColor=[UIColorcolorWithPatternImage:[UIImageimageNamed:imageName]];
}
2.下面我们就开始编写点击button要回调的方法
(1).定义枚举来标示按钮所对应的动画类型，代码如下：

Fade=,//淡入淡出
Push,//推挤
Reveal,//揭开
MoveIn,//覆盖
Cube,//立方体
SuckEffect,//吮吸
OglFlip,//翻转
RippleEffect,//波纹
PageCurl,//翻页
PageUnCurl,//反翻页
CameraIrisHollowOpen,//开镜头
CameraIrisHollowClose,//关镜头
CurlDown,//下翻页
CurlUp,//上翻页
FlipFromLeft,//左翻转
FlipFromRight,//右翻转
}AnimationType; 1
2 UIButtonbutton=sender;
AnimationTypeanimationType=button.tag;
(3).每次点击button都改变subtype的值，包括上,左,下,右

21 NSStringsubtypeString;
switch(_subtype){
case:
subtypeString=kCATransitionFromLeft;
break;
case:
subtypeString=kCATransitionFromBottom;
break;
case:
subtypeString=kCATransitionFromRight;
break;
case:
subtypeString=kCATransitionFromTop;
break;
default:
break;
}
_subtype+=;
if(_subtype>){
_subtype=;
} (4),通过switch结合上边的枚举来判断是那个按钮点击的

{
//各种Case,此处代码下面会给出
} 1

3 caseFade:
[selftransitionWithType:kCATransitionFadeWithSubtype:subtypeStringForView:self.view];
break; 1
2
3 casePush:
[selftransitionWithType:kCATransitionPushWithSubtype:subtypeStringForView:self.view];
break;
效果如下：
(3).揭开效果：

3 caseReveal:
[selftransitionWithType:kCATransitionRevealWithSubtype:subtypeStringForView:self.view];
break; 果图如下：
(4).覆盖效果

3 caseMoveIn:
[selftransitionWithType:kCATransitionMoveInWithSubtype:subtypeStringForView:self.view];
break;
效果图如下：
(5).立方体效果

3 caseCube:
[selftransitionWithType:@"cube"WithSubtype:subtypeStringForView:self.www.visa158.comview];
break; 效果如下：
(6).吮吸效果

3 caseSuckEffect:
[selftransitionWithType:@"suckEffect"WithSubtype:subtypeStringForView:self.view];
break; 效果如下：
(7).翻转效果

3 caseOglFlip:
[selftransitionWithType:@"oglFlip"WithSubtype:subtypeStringForView:self.view];
break; 效果图如下：
8.波纹效果

3 caseRippleEffect:
[selftransitionWithType:@"rippleEffect"WithSubtype:subtypeStringForView:self.www.hunanwang.netview];
break; 1

[selftransitionWithType:@"pageCurl"WithSubtype:subtypeStringForView:self.view];
break;
casePageUnCurl:
[selftransitionWithType:@"pageUnCurl"WithSubtype:subtypeStringForView:self.view];
break;
(10).相机打开效果

[selftransitionWithType:@"cameraIrisHollowOpen"WithSubtype:subtypeStringForView:self.view];
break;
caseCameraIrisHollowClose:
[selftransitionWithType:@"cameraIrisHollowClose"WithSubtype:subtypeStringForView:self.view];
break;
(11),调用上面封装的第二个动画方法

[selfanimationWithView:self.viewWithAnimationTransition:UIViewAnimationTransitionCurlDown];

break;
caseFlipFromLeft:
[selfanimationWithView:self.viewWithAnimationTransition:UIViewAnimationTransitionFlipFromLeft];
break;
caseFlipFromRight:
[selfanimationWithView:self.viewWithAnimationTransition:UIViewAnimationTransitionFlipFromRight];
break;
