Question

我正在使用containerview创建可滑动的选项卡，我现在有三个选项卡，问题是使用滑动手势，我只能左右滑动，因此如何使用滑动来管理三个选项卡

我已经尝试过使用滑动手势，并且对于两个选项卡而言，它的导航都很完美，但是如何通过左右滑动来处理第三个选项卡，让我向您展示我已经尝试过了

代码

@objc func respondToSwipeGesture(_ sender: UIGestureRecognizer) {
    if let swipeGesture = sender as? UISwipeGestureRecognizer {
        switch swipeGesture.direction {
        case UISwipeGestureRecognizer.Direction.right:
            UIView.animate(withDuration: 0.3) {
                self.viewLineOverDue.center = self.viewLineOverCenter
                self.viewLineTodays.center  = self.viewLineOverDue.center
                self.viewFutureLine.center  = self.viewLineOverDue.center
                self.lblOverDue.textColor = UIColor(red: 218/255, green: 55/255, blue: 79/255, alpha: 1)
                self.lblFuture.textColor = UIColor(red: 0, green: 0, blue: 0, alpha: 1)
                self.lblTodays.textColor = UIColor(red: 0, green: 0, blue: 0, alpha: 1)
                self.viewCOnOverdue.isHidden = false
                self.viewCOnFuture.isHidden = true
                self.viewConTodays.isHidden = true
            }
            print("right swipe")
        case UISwipeGestureRecognizer.Direction.left:
            print("leftSwipe")
            UIView.animate(withDuration: 0.3) {
                self.viewLineTodays.center = self.viewLineTodaysCenter
                self.viewLineOverDue.center = self.viewLineTodays.center
                self.viewFutureLine.center = self.viewLineTodays.center
                self.lblTodays.textColor = UIColor(red: 218/255, green: 55/255, blue: 79/255, alpha: 1)
                self.lblFuture.textColor = UIColor(red: 0, green: 0, blue: 0, alpha: 1)
                self.lblOverDue.textColor = UIColor(red: 0, green: 0, blue: 0, alpha: 1)
                self.viewCOnOverdue.isHidden = true
                self.viewCOnFuture.isHidden = true
                self.viewConTodays.isHidden = false
            }
        default:
            break
        }
    }
}

在viewDidLoad（）

    let swipeGestureLeft = UISwipeGestureRecognizer(target: self, action: #selector(CustomTabbarViewController.respondToSwipeGesture(_:)))
    swipeGestureLeft.direction = UISwipeGestureRecognizer.Direction.left
    self.view.addGestureRecognizer(swipeGestureLeft)


 let swipeGestureRight = UISwipeGestureRecognizer(target: self, action:#selector(CustomTabbarViewController.respondToSwipeGesture(_:)) )
        swipeGestureRight.direction = UISwipeGestureRecognizer.Direction.right
        self.view .addGestureRecognizer(swipeGestureRight)

我正在附加我的UI，因此您可以轻松理解

所以我的要求是我想使用滑动手势来滑动三个选项卡

如屏幕快照中所示，我想在两个选项卡上互相导航，就像我的代码一样工作正常，但是如何管理3个选项卡

使用滑动手势在三个选项卡上滑动
