在滑动动画上使用 containerview 创建自定义标签栏

Question

我正在使用容器视图创建自定义可滚动标签栏我使用滑动手势在滑动时滚动我想在滑动时做动画我用过UIview.Animate但我无法获得动画效果让我给你看我的代码

 @objc func respondToSwipeGesture(gesture: UIGestureRecognizer) {
        if let swipeGesture = gesture as? UISwipeGestureRecognizer {
            switch swipeGesture.direction {
            case UISwipeGestureRecognizer.Direction.right:
                print("Swiped right")
                UIView.animate(withDuration: 0.3) {
                    self.viewG1.isHidden = false
                    self.viewG2.isHidden = false

                    self.viewC1.isHidden = true
                    self.viewC2.isHidden = true

                    self.secondContainView.isHidden = true
                    self.firstContainewView.isHidden = false

                }
            case UISwipeGestureRecognizer.Direction.left:
                print("Swiped left")
                UIView.animate(withDuration: 0.3) {
                    self.viewG1.isHidden = true
                    self.viewG2.isHidden = true
                    self.viewC1.isHidden = false
                    self.viewC2.isHidden = false
                    self.firstContainewView.isHidden = true
                    self.secondContainView.isHidden = false
                }
            default:
                break
            }
        }
    }

在viewDidLoad()我写了这段代码

  let swipe = UISwipeGestureRecognizer(target: self, action: #selector(respondToSwipeGesture(gesture:)))
        swipe.direction = UISwipeGestureRecognizer.Direction.right
        self.view.addGestureRecognizer(swipe)

任何人都可以告诉我如何做滑动动画或者我哪里做错了吗

Answer 1

isHidden 属性 of UIView 不可设置动画。使用 alpha 属性获得淡入淡出 in/out 效果。
