Ios 禁用uicollectionview水平滚动的外部平移手势

在我的viewController中，我有一个CollectionView:

mainCollectionView

作为UIView子视图，其中有三个单元格（viewController帧大小）可以水平滚动。

mainCollectionView

还有一个

panGesture

，显示另一个视图控制器：

sideMenuController

在my

mainCollectionView

单元格中，另一个水平滚动的collectionView:

weekCollectionView

作为子视图。当im在

weekCollectionView

中滚动时，如何禁用

PangTesture

和

mainCollectionView

滚动

这是我的密码-

mainCollectionView Pangestree：

fileprivate func setupPanGesture() {
        panGesture = UIPanGestureRecognizer(target: self, action: #selector(panRight(sender:)))
        panGesture.delegate = self
        mainCollectionView.addGestureRecognizer(panGesture)
    }

@objc func panRight(sender: UIPanGestureRecognizer) {
    let translation = sender.translation(in: mainCollectionView)
    let indexPath = NSIndexPath(item: 0, section: 0)
    if (mainCollectionView.cellForItem(at: indexPath as IndexPath) != nil) {
        if translation.x > 0 {
            (UIApplication.shared.keyWindow?.rootViewController as? MasterViewController)?.handlePan(sender: sender)
            mainCollectionView.isScrollEnabled = false
        } else if translation.y > 0 || translation.y < 0 {
            panGesture.isEnabled = false
            mainCollectionView.isScrollEnabled = true
        }
    }
    if (mainCollectionView.cellForItem(at: indexPath as IndexPath) == nil) {
        panGesture.isEnabled = false
        mainCollectionView.isScrollEnabled = true
    }
    panGesture.isEnabled = true
    mainCollectionView.isScrollEnabled = true
}

func gestureRecognizer(_ gestureRecognizer: UIGestureRecognizer, shouldRecognizeSimultaneouslyWith otherGestureRecognizer: UIGestureRecognizer) -> Bool {
    return true
}

fileprivate func setupPanGesture（）{
panGesture=UIPangESTURE识别器（目标：自我，操作：#选择器（右窗格（发送方：））
panGesture.delegate=self
mainCollectionView.AddGestureRecognitor（panGesture）
}
@objc func panRight（发送方：UIPangestureRecognitor）{
让translation=sender.translation（在：mainCollectionView中）
让indexPath=NSIndexPath（项：0，节：0）
if（mainCollectionView.cellForItem（at:indexPath as indexPath）！=nil）{
如果translation.x>0{
（UIApplication.shared.keyWindow？.rootViewController作为？MasterViewController）？.handlePan（发送方：发送方）
mainCollectionView.IsCrollenabled=false
}否则，如果translation.y>0 | | translation.y<0{
panGesture.isEnabled=false
mainCollectionView.IsCrollenabled=true
}
}
if（mainCollectionView.cellForItem（at:indexPath as indexPath）==nil）{
panGesture.isEnabled=false
mainCollectionView.IsCrollenabled=true
}
panGesture.isEnabled=true
mainCollectionView.IsCrollenabled=true
}
func gestureRecognizer（uGestureRecognizer:UIGestureRecognizer，应与其他gestureRecognizer:UIGestureRecognizer同时识别）->Bool{
返回真值
}

为类实现UIgestureRecognitizerDelegate

将手势委托设置为self

panGesture.delegate = self

添加此委托函数

func gestureRecognizer(_ gestureRecognizer: UIGestureRecognizer, shouldRecognizeSimultaneouslyWith otherGestureRecognizer: UIGestureRecognizer) -> Bool {
    if (gestureRecognizer is UIPanGestureRecognizer || gestureRecognizer is UIRotationGestureRecognizer) {
        return true
    } else {
        return false
    }
}
