POP默認支持三種動畫 但同時也支持自定義動畫

POPBasicAnimation //基本動畫

POPSpringAnimation //類似彈簧一般的動畫效果

POPDecayAnimation //過阻尼效果，衰減效果

POPCustomAnimation //自定義動畫

 

一：POPBasicAnimation運用

實例1：創建一個動畫效果，關於視圖透明度的變化，從全透明經過五秒的時間變成alpha為1的不透明效果；此處運用到的POPBasicAnimation類；

- (void)viewDidLoad {
    [super viewDidLoad];
    
    self.view.backgroundColor=[UIColor whiteColor];
    
    //1:初始化一個視圖塊
    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];
    }
    
    //創建一個POPBasicAnimation動畫
    POPBasicAnimation *basicAnimation=[POPBasicAnimation animationWithPropertyNamed:kPOPViewAlpha];
    basicAnimation.fromValue=@(0);
    basicAnimation.toValue=@(1);
    basicAnimation.duration=5; //設置動畫的間隔時間 默認是0.4秒
    basicAnimation.repeatCount=HUGE_VALF; //重復次數 HUGE_VALF設置為無限次重復
    [self.myView pop_addAnimation:basicAnimation forKey:@"myViewAnimation"];
}

其實POP創建動畫的步驟分為三步，a:創建相應的動畫類 b:增加相應的屬性 c:附加到相應的對象上；

上面實例中kPOPViewAlpha是POP為我們封裝好的一個關於透明度的動畫效果；加上屬性就滿足我們的要求；從而也引出POP中一個很關鍵的類POPAnimatableProperty，里面定義的一些常量在今后的運用中非常關鍵；

我們可以簡單看一下POPAnimatableProperty里面定義的一些常量，因為主要針對IOS方面，所以就選出IOS相關的內容：

/**

/**

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

#endif

其實常量對應到其每個UIKIT的一個屬性上，下面把部分列出來，就可以了解到動畫效果是針對什么屬性進行

NSString * const kPOPLayerBackgroundColor = @"backgroundColor";  //背景色
NSString * const kPOPLayerBounds = @"bounds";  //坐標
NSString * const kPOPLayerCornerRadius = @"cornerRadius";  //圓形 值越大,角就越圓
NSString * const kPOPLayerBorderWidth = @"borderWidth";  //邊框寬度
NSString * const kPOPLayerBorderColor = @"borderColor";  //邊框色
NSString * const kPOPLayerOpacity = @"opacity"; //透明度
NSString * const kPOPLayerPosition = @"position"; //位置 position是相對於屏幕的
NSString * const kPOPLayerPositionX = @"positionX";
NSString * const kPOPLayerPositionY = @"positionY";
NSString * const kPOPLayerRotation = @"rotation"; //旋轉
NSString * const kPOPLayerRotationX = @"rotationX";
NSString * const kPOPLayerRotationY = @"rotationY";
NSString * const kPOPLayerScaleX = @"scaleX"; //縮放系數
NSString * const kPOPLayerScaleXY = @"scaleXY"; //XY縮放系數
NSString * const kPOPLayerScaleY = @"scaleY"; //Y縮放系數
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軸平移量
NSString * const kPOPLayerTranslationXY = @"translationXY"; //XY軸平移量
NSString * const kPOPLayerTranslationY = @"translationY"; //Y軸平移量
NSString * const kPOPLayerTranslationZ = @"translationZ"; //Z軸平移量
NSString * const kPOPLayerZPosition = @"zPosition";  //遮擋屬性
NSString * const kPOPLayerShadowColor = @"shadowColor"; //設置陰影
NSString * const kPOPLayerShadowOffset = @"shadowOffset"; //陰影偏移
NSString * const kPOPLayerShadowOpacity = @"shadowOpacity"; //陰影透明度
NSString * const kPOPLayerShadowRadius = @"shadowRadius"; //陰影半徑

// CAShapeLayer
NSString * const kPOPShapeLayerStrokeStart = @"shapeLayer.strokeStart";//strokeStart  動畫的fromValue = 0，toValue = 1 表示從路徑的0位置畫到1 怎么畫是按照清除開始的位置也就是清除0 一直清除到1 效果就是一條路徑慢慢的消失  strokeStart  動畫的fromValue = 1，toValue = 0 表示從路徑的1位置畫到0 怎么畫是按照清除開始的位置也就是1 這樣開始的路徑是空的（即都被清除掉了）一直清除到0 效果就是一條路徑被反方向畫出來
NSString * const kPOPShapeLayerStrokeEnd = @"shapeLayer.strokeEnd";// strokeEnd  動畫的fromValue = 0，toValue = 1  表示 這里我們分3個點說明動畫的順序  strokeEnd從結尾開始清除 首先整條路徑先清除后2/3，接着清除1/3 效果就是正方向畫出路徑     strokeEnd  動畫的fromValue = 1，toValue = 0 效果就是反方向路徑慢慢消失
NSString * const kPOPShapeLayerStrokeColor = @"shapeLayer.strokeColor";  //畫筆的色
NSString * const kPOPShapeLayerFillColor = @"shapeLayer.fillColor";
NSString * const kPOPShapeLayerLineWidth = @"shapeLayer.lineWidth"; //線的寬度
NSString * const kPOPShapeLayerLineDashPhase = @"shapeLayer.lineDashPhase";

從上面的源代碼不難發現，其實針對不同的UIKit都有一些相應的常量，比如在UIView中就有我們上面實例中出現的kPOPViewAlpha；因為POP動畫是針對對象的，所以很多的控件都可以做出相應的動畫效果；CALayer、CAShapeLayer、UIView中相關的常量大部分控件都可以使用；注意像常量kPOPLayerRotation它是作用在層上，所以我們在使用時要把它加載到相應視圖的layer上面；

實例2：創建一個動畫效果，實現一個視圖在延遲2s后經過5秒的時間X軸從50移到300位置的動畫效果；

//2:初始化一個視圖塊
    if (self.myXView==nil) {
        self.myXView=[[UIView alloc]initWithFrame:CGRectMake(50, 210, 50, 50)];
        self.myXView.backgroundColor=[UIColor blueColor];
        [self.view addSubview:self.myXView];
    }
    
    //創建一個POPBasicAnimation動畫 X軸的變化 從50移到300位置
    POPBasicAnimation *anBasic = [POPBasicAnimation animationWithPropertyNamed:kPOPLayerPositionX];
    anBasic.toValue = @(300);
    anBasic.beginTime = CACurrentMediaTime() + 2.0f; //可以用來設置動畫延遲執行時間，若想延遲2s，就設置為CACurrentMediaTime()+2，CACurrentMediaTime()為圖層的當前時間
    anBasic.duration=5;//設置動畫的間隔時間 默認是0.4秒
    [self.myXView pop_addAnimation:anBasic forKey:@"myBackColorViewAnimation”];

實例3：創建一個動畫效果，實現視圖的背影色經過5秒后從黑色變成黃色的動畫效果；

 //3:初始化一個視圖塊
    if (self.myBackColorView==nil) {
        self.myBackColorView=[[UIView alloc]initWithFrame:CGRectMake(250, 100, 50, 50)];
        self.myBackColorView.backgroundColor=[UIColor blackColor];
        [self.view addSubview:self.myBackColorView];
    }
    
    //創建一個POPBasicAnimation動畫 視圖的背影色從黑色經過5秒后漸進變成黃色
    POPBasicAnimation *anBackGroundBasic = [POPBasicAnimation animationWithPropertyNamed:kPOPViewBackgroundColor];
    anBackGroundBasic.toValue=[UIColor yellowColor];
    anBackGroundBasic.duration=5;
    [self.myBackColorView pop_addAnimation:anBackGroundBasic forKey:@"myBackColorViewAnimation”];

從上面三個實例可以發現，其實toValue或FormValue的值都是根據動畫屬性類型來定義，因為它們都是id型；這也決定它們可以是任何類型的值，只要符合我們要求就行；

除了上面那些常用的屬性外，還有一個運行CAMediaTimingFunction:速度控制函數屬性；四種如下：

kCAMediaTimingFunctionLinear（線性）：勻速，給你一個相對靜態的感覺

kCAMediaTimingFunctionEaseIn（漸進）：動畫緩慢進入，然后加速離開

kCAMediaTimingFunctionEaseOut（漸出）：動畫全速進入，然后減速的到達目的地

kCAMediaTimingFunctionEaseInEaseOut（漸進漸出）：動畫緩慢的進入，中間加速，然后減速的到達目的地。這個是默認的動畫行為。

實例4：創建一個POPBasicAnimation動畫 視圖中心以kCAMediaTimingFunctionLinear直線運行到中心點為100,64

    //4:初始化一個視圖塊
    if (self.mytimingFunctionLinearView==nil) {
        self.mytimingFunctionLinearView=[[UIView alloc]initWithFrame:CGRectMake(0, 300, 50, 50)];
        self.mytimingFunctionLinearView.backgroundColor=[UIColor greenColor];
        [self.view addSubview:self.mytimingFunctionLinearView];
    }
    
    //創建一個POPBasicAnimation動畫 視圖中心以kCAMediaTimingFunctionLinear直線運行到中心點為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"];

實例5：創建一個POPBasicAnimation動畫 視圖中心以kCAMediaTimingFunctionEaseInEaseOut直線運行到中心點為200,64

    //5:初始化一個視圖塊
    if (self.mytimingFunctionEaseInEaseOutView==nil) {
        self.mytimingFunctionEaseInEaseOutView=[[UIView alloc]initWithFrame:CGRectMake(100, 300, 50, 50)];
        self.mytimingFunctionEaseInEaseOutView.backgroundColor=[UIColor grayColor];
        [self.view addSubview:self.mytimingFunctionEaseInEaseOutView];
    }
    
    //創建一個POPBasicAnimation動畫 視圖中心以kCAMediaTimingFunctionEaseInEaseOut直線運行到中心點為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比較好的一點是保留了動畫結束后的狀態，通過block回調。如下面的實例視圖塊的大小會被變成100*100

實例6：創建一個POPBasicAnimation動畫 讓視圖塊的大小從50*50 慢慢變到100*100

    //6:初始化一個視圖塊
    if (self.mySizeView==nil) {
        self.mySizeView=[[UIView alloc]initWithFrame:CGRectMake(250, 300, 50, 50)];
        self.mySizeView.backgroundColor=[UIColor redColor];
        [self.view addSubview:self.mySizeView];
    }
    
    //創建一個POPBasicAnimation動畫 讓視圖塊的大小從50*50 慢慢變到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可以在動畫完成后做一些其它的操作；

實例7：創建一個POPBasicAnimation動畫 讓視圖塊的大小從60*30 慢慢變到100*100  動畫完成后又有一個動畫變成60*30

    //7:初始化一個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];
    }

    //創建一個POPBasicAnimation動畫 讓視圖塊的大小從60*30 慢慢變到100*100  動畫完成后又有一個動畫變成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"];

實例8：增加一個動畫 類似心跳的效果，把動畫封裝在方法里面，方便進行遞歸調用；

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

初始化代碼：

    //8:初始化一個CALayer層
    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];
    }

    //增加一個動畫 類似心跳的效果
    [self performAnimation];

把動畫封裝在方法里面，方便進行遞歸調用；

-(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];  //不同的類型 心跳會不一樣
    
    self.animated = !self.animated; //使每次都有區別
    
    anim.completionBlock = ^(POPAnimation *anim, BOOL finished) {
        if (finished) {
            
            [self performAnimation];  //當動畫結束后又遞歸調用，讓它產生一種心跳的效果
        }
    };
    
    [self.myCriLayer pop_addAnimation:anim forKey:@"Animation"];
}

這樣的方式可以在今后很多重復的動畫中進行遞歸運用；

對於forKey是為了可以管理相應的動畫，比如移除動畫之類的，可以簡單了解一下官方的實例

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

移除：

[layer pop_removeAnimationForKey:@"myKey”];

也可以刪除這個上面所有的動畫：

[layer pop_removeAllAnimations];

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

當添加類似[myView pop_addAnimation:animation forKey:@"myKey"];的動畫時，如果你用相同的key添加其他動畫，那么新添加的動畫將會取代先前的動畫。

二：Pop Animation相比於Core Animation的優點

Pop Animation應用於CALayer時，在動畫運行的任何時刻，layer和其presentationLayer的相關屬性值始終保持一致，而Core Animation做不到。

Pop Animation可以應用任何NSObject的對象，而Core Aniamtion必須是CALayer。
