滚动视图未在CollectionView中禁用吗？

Question

我是Swift的新手，正在尝试在collectionView中实现一项功能（启用了滚动。默认情况下，我希望启用滚动功能，而pangesturerecgonizer处于禁用状态。但是在识别出长按之后，滚动将会禁用并启用了平移手势。完成平移手势后，应将其禁用并启用滚动。我有以下代码。

lazy var panGesture: UIPanGestureRecognizer = {
    let pan =  UIPanGestureRecognizer(target: self, action: #selector(self.handlePan(sender:)))
        pan.delegate = self
    return pan
}()

override func viewDidLoad() {
    super.viewDidLoad()

    collectionView.delegate = self
    collectionView.dataSource = self
    collectionView.backgroundColor = UIColor.cyan
    self.view.addSubview(collectionView)

    self.view.addConstraint(NSLayoutConstraint(item: collectionView, attribute: .height, relatedBy: .equal, toItem: self.view, attribute: .height, multiplier: 1.0, constant: 0.0))

    collectionView.translatesAutoresizingMaskIntoConstraints = false
    collectionView.leftAnchor.constraint(equalTo: view.leftAnchor).isActive = true
    collectionView.rightAnchor.constraint(equalTo: view.rightAnchor).isActive = true
    collectionView.bottomAnchor.constraint(equalTo: view.bottomAnchor).isActive = true
    collectionView.addGestureRecognizer(panGesture)
    panGesture.isEnabled = false

    let tap = UILongPressGestureRecognizer(target: self, action: #selector(self.handleTap(sender:)))
    tap.delegate = self
    collectionView.addGestureRecognizer(tap)

}

func handlePan(sender: UIPanGestureRecognizer? = nil) {
    var locationOfBeganTap: CGPoint?

    if sender?.state == .possible { 
    }

    if sender?.state == .ended {
        startTime = NSDate.timeIntervalSinceReferenceDate
    }
}

func handleTap(sender: UIPanGestureRecognizer? = nil){            
    if sender?.state == .began {
        panGesture.isEnabled = true
        self.collectionView!.isScrollEnabled = false
    }

    if sender?.state == .ended {
    }
}

谢谢！

Answer 1

我不明白，您是说触发平移时不能禁用滚动并且平移不再起作用吗？

尝试也为滚动视图添加用户交互：

collectionV.isScrollEnabled = false
collectionV.isUserInteractionEnabled = true

你可以申请

collectionView.isUserInteractionEnabled = true
