Question

我旋转并移动一个物体，但在它完成动画后，它会返回到它的初始位置。我在这里查看了有关此内容的其他帖子，例如：CABasicAnimation resets to initial value after animation completes 但是给出的答案没有用。最受欢迎的答案是：

cabasicanimation.fillMode = kCAFillModeForwards;
cabasicanimation.removedOnCompletion = NO;

没有做任何事情。这是对象的初始化方式：

class coreAnimatedNewView: CALayer {


  var animationGroup = CAAnimationGroup()
  var animationDuration: TimeInterval = 1.5


  override init(layer: Any) {
    super.init(layer: layer)


  }

  required init?(coder aDecoder: NSCoder) {
    super.init(coder: aDecoder)
  }


  init(frame: CGRect) {
    super.init()

    self.frame = frame


      DispatchQueue.main.async {
       self.add(self.createTranslationAnimation(), forKey: "shape")

    }
  }


  //Move Animation
  func createTranslationAnimation () -> CABasicAnimation {
    let moveAnimation = CABasicAnimation(keyPath: "transform.translation")
    moveAnimation.fromValue = NSValue(cgPoint:CGPoint(x: 10, y: 10))
    moveAnimation.toValue = NSValue(cgPoint:CGPoint(x: 120, y: 20))
    moveAnimation.duration = animationDuration

    return moveAnimation

 }
}

设置是动画组的一部分，但我只显示移动功能。

这是它在viewcontroller中的设置方式：

class CoreAnimateViewController: UIViewController {


  //Remember to switch initial viewController on storyboard!!!
  override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(true)

    addShape()

  }

  func addShape () {

    let shape = coreAnimatedNewView(frame: CGRect(x: 10, y: 10, width: 100, height: 100))
    self.view.layer.addSublayer(shape)


  }

}

无论如何都要解决这个问题？

动画完成后，CoreAnimation将重置为初始值
