这些例子都是CABasicAnimation的一些简单实现的动画，例如移动、透明度、翻转等等。方法里面传入一个CALayer类或者子类就可以了。
下面是用swift实现的，这些方法我们也可以用作公共类来调用：
//移动动画position
func addLayerAnimationPosition(layer: CALayer) {
let animation = CABasicAnimation(keyPath: "position")
//开始的位置
animation.fromValue = NSValue(CGPoint: layer.position)
//移动到的位置
animation.toValue = NSValue(CGPoint: CGPointMake(120, 200))
//持续时间
animation.duration = 3
//运动后的位置保持不变（layer的最后位置是toValue）
animation.removedOnCompletion = false
animation.fillMode = kCAFillModeForwards
//添加动画
layer.addAnimation(animation, forKey: "addLayerAnimationPosition")
}
//透明度 opacity
func addLayerAnimationOpacity(layer: CALayer) {
let animation = CABasicAnimation(keyPath: "opacity")
animation.fromValue = 1
animation.toValue = 0
animation.duration = 3
layer.addAnimation(animation, forKey: "addLayerAnimationOpacity")
}
//变大与位置 bounds
func addLayerAnimationBounds(layer:CALayer) {
let animation = CABasicAnimation(keyPath: "bounds")
animation.toValue = NSValue(CGRect:CGRectMake(130, 200, 140, 140))
animation.duration = 3
animation.repeatCount = 1
layer.addAnimation(animation, forKey: "addLayerAnimationBounds")
}
//由小变大 bounds.size
func addLayerAnimationBoundsSize(layer:CALayer) {
let animation = CABasicAnimation(keyPath: "bounds.size")
animation.fromValue = NSValue(CGSize: layer.bounds.size)
animation.toValue = NSValue(CGSize:CGSizeMake(layer.bounds.size.width+20, layer.bounds.size.height+20))
animation.duration = 3
animation.repeatCount = 1
layer.addAnimation(animation, forKey: "addLayerAnimationBoundsSize")
}
//改变颜色 backgroundColor
func addLayerAnimationBackgroundColor(layer:CALayer) {
let animation = CABasicAnimation(keyPath: "backgroundColor")
animation.toValue = UIColor.blueColor().CGColor
animation.duration = 3
animation.repeatCount = 1
layer.addAnimation(animation, forKey: "addLayerAnimationMargin")
}
//渐变圆角 cornerRadius
func addLayerAnimationCornerRadius(layer:CALayer) {
let animation = CABasicAnimation(keyPath: "cornerRadius")
animation.toValue = 30
animation.duration = 3
animation.repeatCount = 1
layer.addAnimation(animation, forKey: "addLayerAnimationCornerRadius")
}
//改变边框border的大小(图形周围边框，border默认为黑色)， borderWidth
func addLayerAnimationBorderWidth(layer:CALayer) {
let animation = CABasicAnimation(keyPath: "borderWidth")
animation.toValue = 10
animation.duration = 3
animation.repeatCount = 1
layer.addAnimation(animation, forKey: "addLayerAnimationBorderWidth")
}
//改变layer内容(图片)，注意如果想要达到改变内容的动画效果，首先在运行动画之前定义好layer的contents contents
func addLayerAnimationContents(layer:CALayer) {
let animation = CABasicAnimation(keyPath: "contents")
let toImage = UIImage.init(named: "通车辆设计矢量素材-06.png")?.CGImage
animation.toValue = toImage
animation.duration = 3
animation.repeatCount = 1
layer.addAnimation(animation, forKey: "addLayerAnimationBounds")
}
//缩放、放大 transform.scale
func addLayerAnimationTransformScale(layer:CALayer) {
let animation = CABasicAnimation(keyPath: "transform.scale")
//开始时的倍率
animation.fromValue = 1.0
//结束时的倍率
animation.toValue = 0.5
animation.duration = 3
animation.repeatCount = 1
animation.autoreverses = true
layer.addAnimation(animation, forKey: "addLayerAnimationScale")
}
//旋转动画(翻转，沿着X轴) transform.rotation.x
func addLayerAnimationTranformRotationX(layer: CALayer) {
let animation = CABasicAnimation(keyPath: "transform.rotation.x")
//旋转180度 = PI
animation.toValue = M_PI
animation.duration = 3
animation.repeatCount = 1
//这里我们可以添加可以不添加，添加一个缓慢进出的动画效果(int/out)。当不添加时，匀速运动，会使用kCAMediaTimingFunctionLinear；当添加时，layer会在开始和结束时比较缓慢
animation.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)
layer.addAnimation(animation, forKey: "addLayerAnimationTranformRotationX")
}
//旋转动画(翻转，沿着Y轴) transform.rotation.y
func addLayerAnimationTranformRotationY(layer: CALayer) {
let animation = CABasicAnimation(keyPath: "transform.rotation.y")
//旋转180度 = PI
animation.toValue = M_PI
animation.duration = 3
animation.repeatCount = 1
//这里我们可以添加可以不添加，添加一个缓慢进出的动画效果(int/out)。当不添加时，匀速运动，会使用kCAMediaTimingFunctionLinear；当添加时，layer会在开始和结束时比较缓慢
animation.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)
layer.addAnimation(animation, forKey: "addLayerAnimationTranformRotationY")
}
//旋转动画（沿着Z轴） transform.rotation.z
func addLayerAnimationTranformRotationZ(layer: CALayer) {
let animation = CABasicAnimation(keyPath: "transform.rotation.z")
//旋转360度 = PI*2
animation.toValue = M_PI*2
animation.duration = 3
animation.repeatCount = 1
//这里我们可以添加可以不添加，添加一个缓慢进出的动画效果(int/out)。当不添加时，匀速运动，会使用kCAMediaTimingFunctionLinear；当添加时，layer会在开始和结束时比较缓慢
animation.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)
layer.addAnimation(animation, forKey: "addLayerAnimationTranformRotationZ")
}
//横向移动（沿着X轴） transform.translation.x
func addLayerAnimationTranformTranslationX(layer: CALayer) {
let animation = CABasicAnimation(keyPath: "transform.translation.x")
animation.toValue = 20
animation.duration = 3
animation.repeatCount = 1
//这里我们可以添加可以不添加，添加一个缓慢进出的动画效果(int/out)。当不添加时，匀速运动，会使用kCAMediaTimingFunctionLinear；当添加时，layer会在开始和结束时比较缓慢
animation.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)
layer.addAnimation(animation, forKey: "addLayerAnimationTranformTranslationX")
}
//纵向移动（沿着Y轴） transform.translation.y
func addLayerAnimationTranformTranslationY(layer: CALayer) {
let animation = CABasicAnimation(keyPath: "transform.translation.y")
animation.toValue = 20
animation.duration = 3
animation.repeatCount = 1
//这里我们可以添加可以不添加，添加一个缓慢进出的动画效果(int/out)。当不添加时，匀速运动，会使用kCAMediaTimingFunctionLinear；当添加时，layer会在开始和结束时比较缓慢
animation.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)
layer.addAnimation(animation, forKey: "addLayerAnimationTranformTranslationY")
}
如果我们只要看keypath的值，我们可以看到下面文章
