swift中的动画

尝试用swift写简单动画。
CABasicAnimation 和CAKeyframeAnimation 的keyPath 都是CALayer的属性或者间接属性，比如"position","position.x",类似的还有backGroundColor，alpha，bounds，borderWidth，只要看CALayer的文档就知道了，因为他们都是继承自CAPropertyAnimation的。而其中复杂的动画也是简单的动画合成的。

func aniation0() {
   let aniamtion = CABasicAnimation.init(keyPath: "position.x")
    aniamtion.toValue = UIScreen.main.bounds.size.width
    aniamtion.duration = 3.0
    aniamtion.repeatCount = 10;
    aniamtion.autoreverses = false
    self.imgeView?.layer.add(aniamtion, forKey: "alpha")
}

func aniation1() {
    let aniamtion = CABasicAnimation.init(keyPath: "bounds")
    aniamtion.fromValue = CGRect.init(origin: CGPoint.init(x: 0, y: 64), size: CGSize.init(width: 240, height: 240))
    aniamtion.toValue = CGRect.init(origin: CGPoint.init(x: 0, y: 64), size: CGSize.init(width: 100, height: 100))
    aniamtion.duration = 3.0;
    aniamtion.repeatCount = 10;
    aniamtion.autoreverses = false;
    self.imgeView?.layer.add(aniamtion, forKey: "bounds");
}

func aniation2() {
    let aniamtion = CABasicAnimation.init(keyPath: "bounds.size")
    aniamtion.fromValue = CGSize.init(width: 240, height: 240)
    aniamtion.toValue = CGSize.init(width: 100, height: 100)
    aniamtion.duration = 3.0;
    aniamtion.repeatCount = 10;
    aniamtion.autoreverses = false;
    self.imgeView?.layer.add(aniamtion, forKey: "bounds.size");
}

func aniation3() {
    let aniamtion = CABasicAnimation.init(keyPath: "anchorPoint")  //取值范围在（0，0）（1，1）
    aniamtion.fromValue = CGPoint.init(x: 0.5, y: 0.5)
    aniamtion.toValue = CGPoint.init(x:0.0, y:0.0);
    aniamtion.duration = 3.0;
    aniamtion.repeatCount = 2;
    aniamtion.autoreverses = false;
    self.imgeView?.layer.add(aniamtion, forKey:"anchorPoint");
}

func aniation4() {
    let aniamtion = CABasicAnimation.init(keyPath: "backgroundColor")
    aniamtion.fromValue = UIColor.red.cgColor
    aniamtion.toValue = UIColor.green.cgColor
    aniamtion.duration = 3.0;
    aniamtion.repeatCount = 2;
    aniamtion.autoreverses = false;
    self.imgeView?.layer.add(aniamtion, forKey:"backgroundColor");
}

func aniation5() {
    let aniamtion = CABasicAnimation.init(keyPath: "cornerRadius")  //取值范围在（0，0）（1，1）
    aniamtion.fromValue = 0
    aniamtion.toValue = 120
    aniamtion.duration = 3.0;
    aniamtion.repeatCount = 2;
    aniamtion.autoreverses = false;
    self.imgeView?.layer.add(aniamtion, forKey:"cornerRadius");
}

func aniation6() {
    let aniamtion = CABasicAnimation.init(keyPath: "borderWidth")  //取值范围在（0，0）（1，1）
    aniamtion.fromValue = 0
    aniamtion.toValue = 10
    aniamtion.duration = 3.0;
    aniamtion.repeatCount = 2;
    aniamtion.autoreverses = false;
    self.imgeView?.layer.add(aniamtion, forKey:"borderWidth");
    
}

func aniation7() {
    let aniamtion = CABasicAnimation.init(keyPath: "borderColor")  //取值范围在（0，0）（1，1）
    aniamtion.fromValue = UIColor.green.cgColor
    aniamtion.toValue = UIColor.blue.cgColor
    aniamtion.duration = 3.0;
    aniamtion.repeatCount = 2;
    aniamtion.autoreverses = false;
    self.imgeView?.layer.borderWidth = 5;
    self.imgeView?.layer.add(aniamtion, forKey:"borderColor");
    
}

func aniation8() {
    let aniamtion = CABasicAnimation.init(keyPath: "opacity")  //取值范围在 0 1 之间
    aniamtion.fromValue = 0
    aniamtion.toValue = 1.0
    aniamtion.duration = 3.0;
    aniamtion.repeatCount = 2;
    aniamtion.autoreverses = false;
    self.imgeView?.layer.add(aniamtion, forKey:"opacity");
    
}

func aniation9() {
   self.aniation0()
   self.aniation1()
    
}

func aniation10() {
   self.aniation1()
   self.aniation2()
    
}

func aniation11() {
   self.aniation2()
   self.aniation3()
    
}

func aniation12() {
   self.aniation3()
   self.aniation4()
    
}

func aniation13() {
   self.aniation4()
   self.aniation5()
    
}

func aniation14() {
   self.aniation5()
   self.aniation6()
    
}

func aniation15() {
   self.aniation6()
   self.aniation7()
   self.aniation8()
}

下面是UIView动画和Keyframe动画

 func aniation0(){
    let aniamtion = CAKeyframeAnimation.init(keyPath: "bounds")
    aniamtion.values = [CGRect.init(x: 0, y: 64, width: 240, height: 240),
                        CGRect.init(x: 0, y: 64, width: 250, height: 250),
                        CGRect.init(x: 0, y: 64, width: 260, height: 260),
                        CGRect.init(x: 0, y: 64, width: 270, height: 270),
                        CGRect.init(x: 0, y: 64, width: 280, height: 280),
                        CGRect.init(x: 0, y: 64, width: 290, height: 290),
                        CGRect.init(x: 0, y: 64, width: 300, height: 300)
                       ]
    aniamtion.timingFunctions = [CAMediaTimingFunction.init(name: kCAMediaTimingFunctionEaseOut)];
    aniamtion.duration = 3;
    aniamtion.calculationMode = kCAAnimationLinear
    self.imgeView?.layer.add(aniamtion, forKey: "bounds")
}

func aniation1(){
    UIView.animate(withDuration: 2.0) {
        self.imgeView?.frame = CGRect.init(x: 0, y: 64, width: 100, height: 100)
    }
}

func aniation2(){
    UIView.animate(withDuration: 2.0, animations: {
        self.imgeView?.backgroundColor = UIColor.green
    }, completion: { (complete) in
        self.imgeView?.frame = CGRect.init(x: 0, y: 64, width: 300, height: 300)
    })
}

func aniation3(){
    UIView.animate(withDuration: 2.0, animations: {
        self.imgeView?.backgroundColor = UIColor.green
    }, completion: { (complete) in
        self.imgeView?.frame = CGRect.init(x: 0, y: 64, width: 300, height: 300)
    })
}

func aniation4(){
    UIView.animate(withDuration: 2.0, delay: 3.0, options: UIViewAnimationOptions.autoreverse, animations: {
        self.imgeView?.frame = CGRect.init(x: 0, y:64, width:100, height:100)
    }) { (true) in
        self.imgeView?.backgroundColor = UIColor.yellow
    }
}

func aniation5(){
   self.imgeView?.frame = CGRect.init(x: 0, y: 64, width: 50, height: 50)
   self.imgeView?.layer.cornerRadius = 25;
   self.imgeView?.layer.masksToBounds = true
    
    let animation = CAKeyframeAnimation.init(keyPath:"position")
    animation.values = [CGRect.init(origin: CGPoint.init(x: 20, y: 64 + 10), size: (self.imgeView?.frame.size)!),
                        CGRect.init(origin: CGPoint.init(x: 30, y: 64 + 20), size: (self.imgeView?.frame.size)!),
                        CGRect.init(origin: CGPoint.init(x: 40, y: 64 + 30), size: (self.imgeView?.frame.size)!),
                        CGRect.init(origin: CGPoint.init(x: 50, y: 64 + 40), size: (self.imgeView?.frame.size)!),
                        CGRect.init(origin: CGPoint.init(x: 60, y: 64 + 50), size: (self.imgeView?.frame.size)!),
                        CGRect.init(origin: CGPoint.init(x: 70, y: 64 + 60), size: (self.imgeView?.frame.size)!),
                        CGRect.init(origin: CGPoint.init(x: 80, y: 64 + 70), size: (self.imgeView?.frame.size)!),
                        CGRect.init(origin: CGPoint.init(x: 90, y: 64 + 80), size: (self.imgeView?.frame.size)!),

                        CGRect.init(origin: CGPoint.init(x: 130, y: 64 + 120), size: (self.imgeView?.frame.size)!)
    ]
    animation.duration = 10;
    animation.fillMode = kCAFillModeForwards
    animation.autoreverses = false
    self.imgeView?.layer.add(animation, forKey: "position")
}

缩放动画

+(void )aniamtionWithView:(UIView *)view{
    CABasicAnimation *animation = [CABasicAnimation animationWithKeyPath:@"transform.scale"];
    animation.duration = 0.4;
    animation.repeatCount = 1;
    animation.autoreverses = YES;
    // 缩放倍数
    animation.fromValue = [NSNumber numberWithFloat:1.0];
    animation.toValue = [NSNumber numberWithFloat:1.2];

    // 添加动画
    [view.layer addAnimation:animation forKey:@"scale-layer"];
}
