swift Animation-CABasicAnimation

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

• 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 = PI2
  animation.toValue = M_PI2
  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")
 }
