IOS swift中的动画的实例详解

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        }}

fromValue：开始值 toValue：结束值 Duration：动画的时间 repeatCount：重复次数

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
