IOSswift中的動畫的實(shí)例詳解

let view = UIView(frame: CGRectMake(10.0, 10.0, 100.0, 40.0))
self.view.addSubview(view)
view.backgroundColor = UIColor.lightGrayColor()
// 位置改變
var frame = view.frame
UIView.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：開始值 
toValue：結(jié)束值 
Duration：動畫的時(shí)間 
repeatCount：重復(fù)次數(shù)

keyPath : 要設(shè)置的屬性 
path : 路徑 可用UIBezierPath（設(shè)置了path，將忽略values） 
duration : 動畫時(shí)長 
repeatCount : 重復(fù)次數(shù) 
calculationMode : 動畫計(jì)算方式 
values：每一個(gè)關(guān)鍵幀（設(shè)置了path，將忽略values） 
removedOnCompletion：執(zhí)行完之后不刪除動畫 
fillMode：執(zhí)行完之后保存最新的狀態(tài) 
delegate：代理
