UIView动画个人笔记，代码简单，不过多赘述。
1.定义三个View

@IBOutlet weak var mFirstView: UIView!
@IBOutlet weak var mSecondView: UIView!//var mOriginFrame: CGRect! //记录view的初始位置 var mFirstSubView: UIView!

2.初始化相关信息

override func viewDidLoad() {super.viewDidLoad()// Do any additional setup after loading the view, typically from a nib.self.mOriginFrame = self.mFirstView.frameself.mFirstSubView = UIView(frame: CGRect(x: 5, y: 5, width: 50, height: 50)) self.mFirstSubView.backgroundColor = UIColor.blackColor() self.mFirstView.addSubview(self.mFirstSubView) }

3.实现相关动画

//简单Y轴平移动画
func basicAnimate() {UIView.animateWithDuration(1) { () -> Void inself.mFirstView.frame.origin.y += 100 } } //可配置option信息动画 func optionAnimate() { UIView.animateWithDuration(3, delay: 0, options: UIViewAnimationOptions.CurveEaseInOut, animations: { () -> Void in self.mFirstView.frame.origin.x += 100 //Nest重写父层option属性 UIView.animateWithDuration(3, delay: 0, options: [UIViewAnimationOptions.OverrideInheritedOptions, UIViewAnimationOptions.OverrideInheritedCurve, UIViewAnimationOptions.CurveEaseOut], animations: { () -> Void in self.mSecondView.frame.origin.x += 100 }, completion: { (finished:Bool) -> Void in }) }) { (finished: Bool) -> Void in } } //试图动画操作子视图 func operateSubview() { UIView.transitionWithView(self.mFirstView, duration: 1, options: [UIViewAnimationOptions.TransitionCrossDissolve, UIViewAnimationOptions.AllowAnimatedContent], animations: { () -> Void in self.mFirstSubView.frame.origin.x += 150 }) { (finished: Bool) -> Void in } } //替换视图动画 func replaceView() { let view = UIView(frame: CGRect(x: 21, y: 150, width: 240, height: 60)) view.backgroundColor = UIColor.magentaColor() UIView.transitionFromView(self.mFirstView, toView: view, duration: 1, options: UIViewAnimationOptions.TransitionCurlUp) { (finished:Bool) -> Void in } } //----------------------核心动画---------------------- /** *显式动画 */ func newBasicAnimate() { //创建一个imageview视图 let imgView = UIImageView(image: UIImage(named: "img")) imgView.frame = CGRect(x: 150, y: 200, width: 100, height: 100) self.view.addSubview(imgView) //1.选定角色 let layer = imgView.layer layer.cornerRadius = 5.0 //2.写剧本 let scaleAnimate = CABasicAnimation(keyPath: "transform.scale") scaleAnimate.fromValue = 1.0 scaleAnimate.toValue = 1.5 scaleAnimate.autoreverses = true scaleAnimate.repeatCount = MAXFLOAT scaleAnimate.duration = 1.0 //第二个剧本 let opaqueAnimate = CABasicAnimation(keyPath: "opacity") opaqueAnimate.fromValue = 0.1 opaqueAnimate.toValue = 1 opaqueAnimate.autoreverses = true opaqueAnimate.repeatCount = MAXFLOAT opaqueAnimate.duration = 1.0 //把剧本交给演员开始动画 layer.addAnimation(scaleAnimate, forKey: "scaleAnimate") layer.addAnimation(opaqueAnimate, forKey: "opacityAnimate") } /** *关键帧动画 */ func newKeyFrameAniamte() { //创建一个imageview视图 let imgView = UIImageView(image: UIImage(named: "img")) imgView.frame = CGRect(x: 200, y: 200, width: 40, height: 40) self.view.addSubview(imgView) //1.选定角色 let layer = imgView.layer layer.cornerRadius = 5.0 //2.写剧本 let keyAnimate = CAKeyframeAnimation(keyPath: "position") //3.设定关键帧 let value0 = NSValue(CGPoint: layer.position) let value1 = NSValue(CGPoint: CGPointMake(layer.position.x, layer.position.y + 200)) let value2 = NSValue(CGPoint: CGPointMake(layer.position.x - 150, layer.position.y + 200)) let value3 = NSValue(CGPoint: CGPointMake(layer.position.x - 150, layer.position.y)) let value4 = NSValue(CGPoint: layer.position) //速度曲线 //let tf0 = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut) //let tf1 = CAMediaTimingFunction(name: kCAMediaTimingFunctionLinear) //let tf2 = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseIn) //let tf3 = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseOut) //keyAnimate.timingFunctions = [tf0, tf1, tf2, tf3] //每段执行的时间 //keyAnimate.keyTimes = [0.0, 0.5, 0.6, 0.7, 1] keyAnimate.values = [value0, value1, value2, value3, value4] keyAnimate.autoreverses = false keyAnimate.repeatCount = MAXFLOAT keyAnimate.duration = 6.0 layer.addAnimation(keyAnimate, forKey: "keyAnimate") }

附：CABasicAnimation的KeyPath
透明度为：opacity
其余如下：
