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 = 3layer.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 = 1layer.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 = 1layer.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 = 1layer.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 = 1layer.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 = 1layer.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 = 1layer.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 = truelayer.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") }
