    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(100, 100, 100, 100)];
            self.myView.backgroundColor=[UIColor redColor];
            self.myView.alpha=0;
            [self.view addSubview:self.myView];
        }
        
        //创建一个POPBasicAnimation动画
        POPBasicAnimation *basicAnimation=[POPBasicAnimation animationWithPropertyNamed:kPOPViewAlpha];
        basicAnimation.fromValue=@(0);
        basicAnimation.toValue=@(1);
        basicAnimation.duration=5; //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:

    /**

    #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(50, 210, 50, 50)];
            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 = @(300);
        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=5;//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(250, 100, 50, 50)];
            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=5;
        [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(0, 300, 50, 50)];
            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(100, 64)];
        anLinearBasic.duration=5;
        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(100, 300, 50, 50)];
            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(200, 64)];
        anEaseInEaseOutBasic.duration=5;
        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(250, 300, 50, 50)];
            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(100, 100)];
        ansizeBasic.duration=5;
        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(50, 300, 60, 30)];
            self.myLabel.backgroundColor=[UIColor redColor];
            self.myLabel.textAlignment=NSTextAlignmentCenter;
            self.myLabel.textColor=[UIColor whiteColor];
            self.myLabel.alpha=1;
            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(100, 100)];
        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(60, 30)];
                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:1 alpha:1].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。

    三:相关属性的值

    一:View Properties
    
    1:Alpha - kPOPViewAlpha
    
    POPBasicAnimation *basicAnimation = [POPBasicAnimation animation];
    basicAnimation.property = [POPAnimatableProperty propertyWithName:kPOPViewAlpha];
    basicAnimation.toValue= @(0); // scale from 0 to 1
    
    2:Color - kPOPViewBackgroundColor POPSpringAnimation *basicAnimation = [POPSpringAnimation animation]; basicAnimation.property = [POPAnimatableProperty propertyWithName: kPOPViewBackgroundColor]; basicAnimation.toValue= [UIColor redColor];
    3:Size
    - kPOPViewBounds POPBasicAnimation *basicAnimation = [POPBasicAnimation animation]; basicAnimation.property = [POPAnimatableProperty propertyWithName:kPOPViewBounds]; basicAnimation.toValue=[NSValue valueWithCGRect:CGRectMake(0, 0, 90, 190)]; //first 2 values dont matter
    4:Center - kPOPViewCenter POPBasicAnimation *basicAnimation = [POPBasicAnimation animation]; basicAnimation.property = [POPAnimatableProperty propertyWithName:kPOPViewCenter]; basicAnimation.toValue=[NSValue valueWithCGPoint:CGPointMake(200, 200)];
    5:Location
    & Size - kPOPViewFrame POPBasicAnimation *basicAnimation = [POPBasicAnimation animation]; basicAnimation.property = [POPAnimatableProperty propertyWithName:kPOPViewFrame]; basicAnimation.toValue=[NSValue valueWithCGRect:CGRectMake(140, 140, 140, 140)];
    6:Size
    - kPOPViewScaleXY POPBasicAnimation *basicAnimation = [POPBasicAnimation animation]; basicAnimation.property = [POPAnimatableProperty propertyWithName:kPOPViewScaleXY]; basicAnimation.toValue=[NSValue valueWithCGSize:CGSizeMake(3, 2)];
    7:Size(Scale)
    - kPOPViewSize POPBasicAnimation *basicAnimation = [POPBasicAnimation animation]; basicAnimation.property = [POPAnimatableProperty propertyWithName:kPOPViewSize]; basicAnimation.toValue=[NSValue valueWithCGSize:CGSizeMake(30, 200)];
    二:Layer Properties 1:Color
