POP默认支持三种动画 但同时也支持自定义动画

POPBasicAnimation //基本动画

POPSpringAnimation //类似弹簧一般的动画效果

POPDecayAnimation //过阻尼效果，衰减效果

POPCustomAnimation //自定义动画

一：POPBasicAnimation运用

实例1：创建一个动画效果，关于视图透明度的变化，从全透明经过五秒的时间变成alpha为1的不透明效果；此处运用到的POPBasicAnimation类；

- (void)viewDidLoad {
    [super viewDidLoad];

    self.view.backgroundColor=[UIColor whiteColor];

    //1:初始化一个视图块
    if (self.myView==nil) {
        self.myView=[[UIView alloc]initWithFrame:CGRectMake(, , , )];
        self.myView.backgroundColor=[UIColor redColor];
        self.myView.alpha=;
        [self.view addSubview:self.myView];
    }

    //创建一个POPBasicAnimation动画
    POPBasicAnimation *basicAnimation=[POPBasicAnimation animationWithPropertyNamed:kPOPViewAlpha];
    basicAnimation.fromValue=@();
    basicAnimation.toValue=@();
    basicAnimation.duration=; //设置动画的间隔时间 默认是0.4秒
    basicAnimation.repeatCount=HUGE_VALF; //重复次数 HUGE_VALF设置为无限次重复
    [self.myView pop_addAnimation:basicAnimation forKey:@"myViewAnimation"];
}

其实POP创建动画的步骤分为三步，a:创建相应的动画类 b:增加相应的属性 c:附加到相应的对象上；

上面实例中kPOPViewAlpha是POP为我们封装好的一个关于透明度的动画效果；加上属性就满足我们的要求；从而也引出POP中一个很关键的类POPAnimatableProperty，里面定义的一些常量在今后的运用中非常关键；

我们可以简单看一下POPAnimatableProperty里面定义的一些常量，因为主要针对IOS方面，所以就选出IOS相关的内容：

/**

 */
extern NSString * const kPOPLayerBackgroundColor;
extern NSString * const kPOPLayerBounds;
extern NSString * const kPOPLayerCornerRadius;

/**

extern NSString * const kPOPWindowFrame;
extern NSString * const kPOPWindowAlphaValue;
extern NSString * const kPOPWindowBackgroundColor;

#endif

其实常量对应到其每个UIKIT的一个属性上，下面把部分列出来，就可以了解到动画效果是针对什么属性进行

NSString * const kPOPLayerBackgroundColor = @"backgroundColor";  //背景色
NSString * const kPOPLayerBounds = @"bounds";  //坐标
NSString * const kPOPLayerCornerRadius = @"cornerRadius";  //圆形 值越大,角就越圆
NSString * const kPOPLayerBorderWidth = @"borderWidth";  //边框宽度
NSString * const kPOPLayerBorderColor = @"borderColor";  //边框色
NSString * const kPOPLayerOpacity = @"opacity"; //透明度
NSString * const kPOPLayerPosition = @"position"; //位置 position是相对于屏幕的
NSString * const kPOPLayerPositionX = @"positionX";
NSString * const kPOPLayerPositionY = @"positionY";
NSString * const kPOPLayerRotation = @"rotation"; //旋转
NSString * const kPOPLayerRotationX = @"rotationX";
NSString * const kPOPLayerRotationY = @"rotationY";
NSString * const kPOPLayerScaleX = @"scaleX"; //缩放系数
NSString * const kPOPLayerScaleXY = @"scaleXY"; //XY缩放系数
NSString * const kPOPLayerScaleY = @"scaleY"; //Y缩放系数
NSString * const kPOPLayerSize = @"size";  //大小
NSString * const kPOPLayerSubscaleXY = @"subscaleXY";
NSString * const kPOPLayerSubtranslationX = @"subtranslationX";
NSString * const kPOPLayerSubtranslationXY = @"subtranslationXY";
NSString * const kPOPLayerSubtranslationY = @"subtranslationY";
NSString * const kPOPLayerSubtranslationZ = @"subtranslationZ";
NSString * const kPOPLayerTranslationX = @"translationX"; //X轴平移量
NSString * const kPOPLayerTranslationXY = @"translationXY"; //XY轴平移量
NSString * const kPOPLayerTranslationY = @"translationY"; //Y轴平移量
NSString * const kPOPLayerTranslationZ = @"translationZ"; //Z轴平移量
NSString * const kPOPLayerZPosition = @"zPosition";  //遮挡属性
NSString * const kPOPLayerShadowColor = @"shadowColor"; //设置阴影
NSString * const kPOPLayerShadowOffset = @"shadowOffset"; //阴影偏移
NSString * const kPOPLayerShadowOpacity = @"shadowOpacity"; //阴影透明度
NSString * const kPOPLayerShadowRadius = @"shadowRadius"; //阴影半径

// CAShapeLayer
NSString * const kPOPShapeLayerStrokeStart = @"shapeLayer.strokeStart";//strokeStart  动画的fromValue = 0，toValue = 1 表示从路径的0位置画到1 怎么画是按照清除开始的位置也就是清除0 一直清除到1 效果就是一条路径慢慢的消失  strokeStart  动画的fromValue = 1，toValue = 0 表示从路径的1位置画到0 怎么画是按照清除开始的位置也就是1 这样开始的路径是空的（即都被清除掉了）一直清除到0 效果就是一条路径被反方向画出来
NSString * const kPOPShapeLayerStrokeEnd = @"shapeLayer.strokeEnd";// strokeEnd  动画的fromValue = 0，toValue = 1  表示 这里我们分3个点说明动画的顺序  strokeEnd从结尾开始清除 首先整条路径先清除后2/3，接着清除1/3 效果就是正方向画出路径     strokeEnd  动画的fromValue = 1，toValue = 0 效果就是反方向路径慢慢消失
NSString * const kPOPShapeLayerStrokeColor = @"shapeLayer.strokeColor";  //画笔的色
NSString * const kPOPShapeLayerFillColor = @"shapeLayer.fillColor";
NSString * const kPOPShapeLayerLineWidth = @"shapeLayer.lineWidth"; //线的宽度
NSString * const kPOPShapeLayerLineDashPhase = @"shapeLayer.lineDashPhase";

从上面的源代码不难发现，其实针对不同的UIKit都有一些相应的常量，比如在UIView中就有我们上面实例中出现的kPOPViewAlpha；因为POP动画是针对对象的，所以很多的控件都可以做出相应的动画效果；CALayer、CAShapeLayer、UIView中相关的常量大部分控件都可以使用；注意像常量kPOPLayerRotation它是作用在层上，所以我们在使用时要把它加载到相应视图的layer上面；

实例2：创建一个动画效果，实现一个视图在延迟2s后经过5秒的时间X轴从50移到300位置的动画效果；

//2:初始化一个视图块
    if (self.myXView==nil) {
        self.myXView=[[UIView alloc]initWithFrame:CGRectMake(, , , )];
        self.myXView.backgroundColor=[UIColor blueColor];
        [self.view addSubview:self.myXView];
    }

    //创建一个POPBasicAnimation动画 X轴的变化 从50移到300位置
    POPBasicAnimation *anBasic = [POPBasicAnimation animationWithPropertyNamed:kPOPLayerPositionX];
    anBasic.toValue = @();
    anBasic.beginTime = CACurrentMediaTime() + 2.0f; //可以用来设置动画延迟执行时间，若想延迟2s，就设置为CACurrentMediaTime()+2，CACurrentMediaTime()为图层的当前时间
    anBasic.duration=;//设置动画的间隔时间 默认是0.4秒
    [self.myXView pop_addAnimation:anBasic forKey:@"myBackColorViewAnimation”];

实例3：创建一个动画效果，实现视图的背影色经过5秒后从黑色变成黄色的动画效果；

 //3:初始化一个视图块
    if (self.myBackColorView==nil) {
        self.myBackColorView=[[UIView alloc]initWithFrame:CGRectMake(, , , )];
        self.myBackColorView.backgroundColor=[UIColor blackColor];
        [self.view addSubview:self.myBackColorView];
    }

    //创建一个POPBasicAnimation动画 视图的背影色从黑色经过5秒后渐进变成黄色
    POPBasicAnimation *anBackGroundBasic = [POPBasicAnimation animationWithPropertyNamed:kPOPViewBackgroundColor];
    anBackGroundBasic.toValue=[UIColor yellowColor];
    anBackGroundBasic.duration=;
    [self.myBackColorView pop_addAnimation:anBackGroundBasic forKey:@"myBackColorViewAnimation”];

从上面三个实例可以发现，其实toValue或FormValue的值都是根据动画属性类型来定义，因为它们都是id型；这也决定它们可以是任何类型的值，只要符合我们要求就行；

除了上面那些常用的属性外，还有一个运行CAMediaTimingFunction:速度控制函数属性；四种如下：

kCAMediaTimingFunctionLinear（线性）：匀速，给你一个相对静态的感觉

kCAMediaTimingFunctionEaseIn（渐进）：动画缓慢进入，然后加速离开

kCAMediaTimingFunctionEaseOut（渐出）：动画全速进入，然后减速的到达目的地

kCAMediaTimingFunctionEaseInEaseOut（渐进渐出）：动画缓慢的进入，中间加速，然后减速的到达目的地。这个是默认的动画行为。

实例4：创建一个POPBasicAnimation动画 视图中心以kCAMediaTimingFunctionLinear直线运行到中心点为100,64

    //4:初始化一个视图块
    if (self.mytimingFunctionLinearView==nil) {
        self.mytimingFunctionLinearView=[[UIView alloc]initWithFrame:CGRectMake(, , , )];
        self.mytimingFunctionLinearView.backgroundColor=[UIColor greenColor];
        [self.view addSubview:self.mytimingFunctionLinearView];
    }

    //创建一个POPBasicAnimation动画 视图中心以kCAMediaTimingFunctionLinear直线运行到中心点为100,64
    POPBasicAnimation *anLinearBasic = [POPBasicAnimation animationWithPropertyNamed:kPOPViewCenter];
    anLinearBasic.toValue=[NSValue valueWithCGPoint:CGPointMake(, )];
    anLinearBasic.duration=;
    anLinearBasic.timingFunction=[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionLinear];
    [self.mytimingFunctionLinearView pop_addAnimation:anLinearBasic forKey:@"myLinearBasic"];

实例5：创建一个POPBasicAnimation动画 视图中心以kCAMediaTimingFunctionEaseInEaseOut直线运行到中心点为200,64

    //5:初始化一个视图块
    if (self.mytimingFunctionEaseInEaseOutView==nil) {
        self.mytimingFunctionEaseInEaseOutView=[[UIView alloc]initWithFrame:CGRectMake(, , , )];
        self.mytimingFunctionEaseInEaseOutView.backgroundColor=[UIColor grayColor];
        [self.view addSubview:self.mytimingFunctionEaseInEaseOutView];
    }

    //创建一个POPBasicAnimation动画 视图中心以kCAMediaTimingFunctionEaseInEaseOut直线运行到中心点为200,64
    POPBasicAnimation *anEaseInEaseOutBasic = [POPBasicAnimation animationWithPropertyNamed:kPOPViewCenter];
    anEaseInEaseOutBasic.toValue=[NSValue valueWithCGPoint:CGPointMake(, )];
    anEaseInEaseOutBasic.duration=;
    anEaseInEaseOutBasic.timingFunction=[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
    [self.mytimingFunctionEaseInEaseOutView pop_addAnimation:anEaseInEaseOutBasic forKey:@"mytimingFunctionEaseInEaseOutView”];

POP比较好的一点是保留了动画结束后的状态，通过block回调。如下面的实例视图块的大小会被变成100*100

实例6：创建一个POPBasicAnimation动画 让视图块的大小从50*50 慢慢变到100*100

    //6:初始化一个视图块
    if (self.mySizeView==nil) {
        self.mySizeView=[[UIView alloc]initWithFrame:CGRectMake(, , , )];
        self.mySizeView.backgroundColor=[UIColor redColor];
        [self.view addSubview:self.mySizeView];
    }

    //创建一个POPBasicAnimation动画 让视图块的大小从50*50 慢慢变到100*100
    POPBasicAnimation *ansizeBasic = [POPBasicAnimation animationWithPropertyNamed:kPOPViewSize];
    ansizeBasic.toValue=[NSValue valueWithCGSize:CGSizeMake(, )];
    ansizeBasic.duration=;
    ansizeBasic.repeatCount=HUGE_VALF;
    [self.mySizeView pop_addAnimation:ansizeBasic forKey:@"mySizeView”];

setCompletionBlock可以在动画完成后做一些其它的操作；

实例7：创建一个POPBasicAnimation动画 让视图块的大小从60*30 慢慢变到100*100  动画完成后又有一个动画变成60*30

    //7:初始化一个Label
    if (self.myLabel==nil) {
        self.myLabel=[[UILabel alloc]initWithFrame:CGRectMake(, , , )];
        self.myLabel.backgroundColor=[UIColor redColor];
        self.myLabel.textAlignment=NSTextAlignmentCenter;
        self.myLabel.textColor=[UIColor whiteColor];
        self.myLabel.alpha=;
        self.myLabel.text=@"Label";
        [self.view addSubview:self.myLabel];
    }

    //创建一个POPBasicAnimation动画 让视图块的大小从60*30 慢慢变到100*100  动画完成后又有一个动画变成60*30
    POPBasicAnimation* anLabelBasic = [POPBasicAnimation animationWithPropertyNamed:kPOPViewSize];
    anLabelBasic.duration=3.0;
    anLabelBasic.toValue = [NSValue valueWithCGSize:CGSizeMake(, )];
    anLabelBasic.timingFunction =[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
    [anLabelBasic setCompletionBlock:^(POPAnimation *ani, BOOL fin) {
        if (fin) {
            NSLog(@"self.myLabel.frame=%@",NSStringFromCGRect(self.myLabel.frame));

            POPBasicAnimation *newLabelAnimation=[POPBasicAnimation animationWithPropertyNamed:kPOPViewSize];
            newLabelAnimation.duration=3.0;
            newLabelAnimation.toValue = [NSValue valueWithCGSize:CGSizeMake(, )];
            newLabelAnimation.timingFunction =[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
            [self.myLabel pop_addAnimation:newLabelAnimation forKey:@"newMyLabelAnimation"];
        }
    }];
    [self.myLabel pop_addAnimation:anLabelBasic forKey:@"myLabelAnimation"];

实例8：增加一个动画 类似心跳的效果，把动画封装在方法里面，方便进行递归调用；

@property(nonatomic)CALayer *myCriLayer;
@property (nonatomic) BOOL animated;

初始化代码：

    //8:初始化一个CALayer层
    if (self.myCriLayer==nil) {
        self.myCriLayer=[CALayer layer];
        [self.myCriLayer pop_removeAllAnimations];
        self.myCriLayer.opacity = 1.0;
        self.myCriLayer.transform = CATransform3DIdentity;
        [self.myCriLayer setMasksToBounds:YES];
        [self.myCriLayer setBackgroundColor:[UIColor colorWithRed:0.16 green:0.72 blue: alpha:].CGColor];
        [self.myCriLayer setCornerRadius:15.0f];
        [self.myCriLayer setBounds:CGRectMake(0.0f, 0.0f, 30.0f, 30.0f)];
        self.myCriLayer.position = CGPointMake(self.view.center.x, 380.0);
        [self.view.layer addSublayer:self.myCriLayer];
    }

    //增加一个动画 类似心跳的效果
    [self performAnimation];

把动画封装在方法里面，方便进行递归调用；

-(void)performAnimation
{
    [self.myCriLayer pop_removeAllAnimations];
    POPBasicAnimation *anim = [POPBasicAnimation animationWithPropertyNamed:kPOPLayerScaleXY];

    if (self.animated) {
        anim.toValue = [NSValue valueWithCGPoint:CGPointMake(1.0, 1.0)];
    }else{
        anim.toValue = [NSValue valueWithCGPoint:CGPointMake(2.0, 2.0)];
    }

    anim.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];  //不同的类型 心跳会不一样

    self.animated = !self.animated; //使每次都有区别

    anim.completionBlock = ^(POPAnimation *anim, BOOL finished) {
        if (finished) {

            [self performAnimation];  //当动画结束后又递归调用，让它产生一种心跳的效果
        }
    };

    [self.myCriLayer pop_addAnimation:anim forKey:@"Animation"];
}

这样的方式可以在今后很多重复的动画中进行递归运用；

对于forKey是为了可以管理相应的动画，比如移除动画之类的，可以简单了解一下官方的实例

POPSpringAnimation *anim = [POPSpringAnimation animation];
...
[layer pop_addAnimation:anim forKey:@"myKey”];

移除：

[layer pop_removeAnimationForKey:@"myKey”];

也可以删除这个上面所有的动画：

[layer pop_removeAllAnimations];

可以判断是否存在
anim = [layer pop_animationForKey:@"myKey"];
if (anim) {
  /* update to value to new destination */
  anim.toValue = @(42.0);
} else {
  /* create and start a new animation */
  ....
}

当添加类似[myView pop_addAnimation:animation forKey:@"myKey"];的动画时，如果你用相同的key添加其他动画，那么新添加的动画将会取代先前的动画。

二：Pop Animation相比于Core Animation的优点

Pop Animation应用于CALayer时，在动画运行的任何时刻，layer和其presentationLayer的相关属性值始终保持一致，而Core Animation做不到。

Pop Animation可以应用任何NSObject的对象，而Core Aniamtion必须是CALayer。
