================
注：其中有些效果调用了CATransition的Private API, 仅供娱乐。
补充：还是有好多小伙伴问那些可以在AppStore中使用，调用私有API的肯定是不行的，而下方有些就调用了私有API。
下方会用到一些私有API, 有些效果在APPStore中是不能使用的，私有API如下：
```Objective-C
NSString *const kCATransitionCube = @"cube";
NSString *const kCATransitionSuckEffect = @"suckEffect";
NSString *const kCATransitionOglFlip = @"oglFlip";
NSString *const kCATransitionRippleEffect = @"rippleEffect";
NSString *const kCATransitionPageCurl = @"pageCurl";
NSString *const kCATransitionPageUnCurl = @"pageUnCurl";
NSString *const kCATransitionCameraIrisHollowOpen = @"cameraIrisHollowOpen";
NSString *const kCATransitionCameraIrisHollowClose = @"cameraIrisHollowClose";
```
而下方这些可以放心使用：
```Objective-C
// CAAnimation.h
/* Common transition types. */
CA_EXTERN NSString * const kCATransitionFade
__OSX_AVAILABLE_STARTING (__MAC_10_5, __IPHONE_2_0);
CA_EXTERN NSString * const kCATransitionMoveIn
__OSX_AVAILABLE_STARTING (__MAC_10_5, __IPHONE_2_0);
CA_EXTERN NSString * const kCATransitionPush
__OSX_AVAILABLE_STARTING (__MAC_10_5, __IPHONE_2_0);
CA_EXTERN NSString * const kCATransitionReveal
__OSX_AVAILABLE_STARTING (__MAC_10_5, __IPHONE_2_0);
```
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。
```Objective-C
#pragma CATransition动画实现
- (void) transitionWithType:(NSString *) type WithSubtype:(NSString *) subtype ForView : (UIView *) view
{
//创建CATransition对象
CATransition *animation = [CATransition animation];
//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.layer addAnimation:animation forKey:@"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
```Objective-C
#pragma UIView实现动画
- (void) animationWithView : (UIView *)view WithAnimationTransition : (UIViewAnimationTransition) transition
{
[UIView animateWithDuration:DURATION animations:^{
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationTransition:transition forView:view cache:YES];
}];
}
```
#### 3.改变View的背景图，便于切换时观察
```Objective-C
#pragma 给View添加背景图
-(void)addBgImageWithImageName:(NSString *) imageName
{
self.view.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:imageName]];
}
```
## 二.调用上面的方法实现我们想要的动画
#### 1.我们在View上添加多个Button,给不同的Button设置不同的Tag值，然后再ViewController中绑定同一个方法，点击不同的button实现不同的页面切换效果。storyBoard上的控件效果如下图所示：
#### 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：
```Objective-C
typedef enum : NSUInteger {
Fade = 1, //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;
```
(2),获取Button的Tag值：
```Objective-C
UIButton *button = sender;
AnimationType animationType = button.tag;
```
(3).每次点击button都改变subtype的值，包括上,左,下,右
```Objective-C
NSString *subtypeString;
switch (_subtype) {
case 0:
subtypeString = kCATransitionFromLeft;
break;
case 1:
subtypeString = kCATransitionFromBottom;
break;
case 2:
subtypeString = kCATransitionFromRight;
break;
case 3:
subtypeString = kCATransitionFromTop;
break;
default:
break;
}
_subtype += 1;
if (_subtype > 3) {
_subtype = 0;
}
```
(4),通过switch结合上边的枚举来判断是那个按钮点击的
```Objective-C
switch (animationType)
{
//各种Case,此处代码下面会给出
}
```
#### 3.调用我们封装的运动方法，来实现动画效果
(1),淡化效果
```Objective-C
case Fade:
[self transitionWithType:kCATransitionFade WithSubtype:subtypeString ForView:self.view];
break;
```
(2) PUSH效果
```Objective-C
case Push:
[self transitionWithType:kCATransitionPush WithSubtype:subtypeString ForView:self.view];
break;
```
(3)、揭开效果
```Objective-C
case Reveal:
[self transitionWithType:kCATransitionReveal WithSubtype:subtypeString ForView:self.view];
break;
```
(4)、覆盖效果
```Objective-C
case MoveIn:
[self transitionWithType:kCATransitionMoveIn WithSubtype:subtypeString ForView:self.view];
break;
```
(5)、立方体切换
```Objective-C
case Cube:
[self transitionWithType:@"cube" WithSubtype:subtypeString ForView:self.view];
break;
```
(6)、吮吸效果
```Objective-C
case SuckEffect:
[self transitionWithType:@"suckEffect" WithSubtype:subtypeString ForView:self.view];
break;
```
(7)、翻转效果
```Objective-C
case OglFlip:
[self transitionWithType:@"oglFlip" WithSubtype:subtypeString ForView:self.view];
break;
```
(8)、波纹效果
```Objective-C
case RippleEffect:
[self transitionWithType:@"rippleEffect" WithSubtype:subtypeString ForView:self.view];
break;
```
(9)、翻页效果
```Objective-C
case PageCurl:
[self transitionWithType:@"pageCurl" WithSubtype:subtypeString ForView:self.view];
break;
case PageUnCurl:
[self transitionWithType:@"pageUnCurl" WithSubtype:subtypeString ForView:self.view];
break;
```
(10)、相机打开效果
```Objective-C
case CameraIrisHollowOpen:
[self transitionWithType:@"cameraIrisHollowOpen" WithSubtype:subtypeString ForView:self.view];
break;
case CameraIrisHollowClose:
[self transitionWithType:@"cameraIrisHollowClose" WithSubtype:subtypeString ForView:self.view];
break;
```
(11),调用上面封装的第二个动画方法
```Objective-C
case CurlDown:
[self animationWithView:self.view WithAnimationTransition:UIViewAnimationTransitionCurlDown];
break;
case CurlUp:
[self animationWithView:self.view WithAnimationTransition:UIViewAnimationTransitionCurlUp];
break;
case FlipFromLeft:
[self animationWithView:self.view WithAnimationTransition:UIViewAnimationTransitionFlipFromLeft];
break;
case FlipFromRight:
[self animationWithView:self.view WithAnimationTransition:UIViewAnimationTransitionFlipFromRight];
break;
```
