swift中的动画

UIView的通用动画

let view = UIView(frame: CGRectMake(10.0, 10.0, 100.0, 40.0))self.view.addSubview(view)view.backgroundColor = UIColor.lightGrayColor()// 位置改变var frame = view.frameUIView.animateWithDuration(0.6, delay: 2.0, options: UIViewAnimationOptions.CurveEaseInOut, animations: {            () -> Void in            frame.origin.x = 200.0            view.frame = frame            }) {                (finished:Bool) -> Void in                UIView.animateWithDuration(0.6) {                    () -> Void in                    frame.origin.x = 10.0                    view.frame = frame                }}

CABasicAnimation核心动画
1、CABasicAnimation类只有三个属性：
fromValue：开始值
toValue：结束值
Duration：动画的时间
repeatCount：重复次数

2、通过animationWithKeyPath键值对的方式设置不同的动画效果

let view = UILabel(frame: CGRectMake((self.view.frame.size.width - 200.0) / 2, 10.0, 200.0, 40.0))self.view.addSubview(view)view.text = "缩放/淡入淡出"view.textAlignment = .Centerview.adjustsFontSizeToFitWidth = trueview.backgroundColor = UIColor.lightGrayColor()//let layer = view.layer// 开始动画// 缩放let scaleAnimate = CABasicAnimation(keyPath: "transform.scale")scaleAnimate.fromValue = 1.0scaleAnimate.toValue = 1.5scaleAnimate.autoreverses = truescaleAnimate.repeatCount = MAXFLOATscaleAnimate.duration = 1.0// 淡入淡出let opaqueAnimate = CABasicAnimation(keyPath: "opacity")opaqueAnimate.fromValue = 0.1opaqueAnimate.toValue = 1opaqueAnimate.autoreverses = trueopaqueAnimate.repeatCount = MAXFLOATopaqueAnimate.duration = 1.0layer.addAnimation(scaleAnimate, forKey: "scaleAnimate")layer.addAnimation(opaqueAnimate, forKey: "opacityAnimate")

CAKeyframeAnimation关键帧动画
主要属性:
keyPath : 要设置的属性
path : 路径 可用UIBezierPath（设置了path，将忽略values）
duration : 动画时长
repeatCount : 重复次数
calculationMode : 动画计算方式
values：每一个关键帧（设置了path，将忽略values）
removedOnCompletion：执行完之后不删除动画
fillMode：执行完之后保存最新的状态
delegate：代理
