我有这样一个想这样做的情况下刷新后几秒钟都加载了微光和完成动画。我的代码starAnimatiom:

func startAnimation() {
        for animateView in getSubViewsForAnimate() {
            animateView.clipsToBounds = true
            let gradientLayer = CAGradientLayer()
            gradientLayer.colors = [UIColor.clear.cgColor, UIColor.white.withAlphaComponent(0.8).cgColor, UIColor.clear.cgColor]
            gradientLayer.startPoint = CGPoint(x: 0.7, y: 1.0)
            gradientLayer.endPoint = CGPoint(x: 0.0, y: 0.8)
            gradientLayer.frame = animateView.bounds
            animateView.layer.mask = gradientLayer

            let animation = CABasicAnimation(keyPath: "transform.translation.x")
            animation.duration = 1.5
            animation.fromValue = -animateView.frame.size.width
            animation.toValue = animateView.frame.size.width
            animation.repeatCount = .infinity

            gradientLayer.add(animation, forKey: "")
        }
    }
    func getSubViewsForAnimate() -> [UIView] {
        var obj: [UIView] = []
        for objView in view.subviewsRecursive() {
            obj.append(objView)
        }
        return obj.filter({ (obj) -> Bool in
            obj.shimmerAnimation

        })
    }

我的代码函数停止动画;

@objc func stopAnimation() {
        for animateView in getSubViewsForAnimate() {
            animateView.layer.removeAllAnimations()
            animateView.layer.mask = nil
            timerShimmer.invalidate()
            refresh.endRefreshing()


        }


    }

当我下拉并进行更新时,动画仍在继续,但由于某些原因没有停。什么我做错了吗?

 @objc func obnova() {


        self.startAnimation()
        self.tableView.reloadData()

        self.loadObjects1()
        self.loadObjects2()
        self.loadObjects3()

      // self.refresh.endRefreshing()

    }



override func viewDidLoad() {
        super.viewDidLoad()

 timerShimmer = Timer.init(timeInterval: 0.2, target: self, selector: #selector(stopAnimation), userInfo: nil, repeats: true)
}

请帮帮我?

像下面这样更改最后一个部分并尝试

func startTimer() {
    if timerShimmer != nil {
        timerShimmer.invalidate()
        timerShimmer = nil
    }

    timerShimmer = Timer.init(timeInterval: 0.2, target: self, selector: #selector(stopAnimation), userInfo: nil, repeats: true)
}

@objc func obnova() {
    self.startAnimation()
    self.tableView.reloadData()

    self.loadObjects1()
    self.loadObjects2()
    self.loadObjects3()
    startTimer()
}

override func viewDidLoad() {
    super.viewDidLoad()
    startTimer()
}
