Question

我的应用使用了PageViewController，3个NavigationControllers和3个ViewControllers。您可以从一个VC滑动到另一个VC。看动画gif。

在VC中有TableViews，其中包含leading和trailingSwipeActions。令我遗憾的是，领先的滑动动作仅适用于第一个VC。尾随滑动操作仅适用于最后一个VC。

解决方案是，如果PageViewController的滑动仅适用于图片区域，而不是在tableviews区域。

对于前导和尾随滑动动作，只需一个小动作即可。对于PageViewController滑动，它必须是一个很大的运动。我不知道这是否可以继续。

发现了很多问题和一些例子，但我无法让他们处理我的用例。

PageViewController的代码：

class PageViewController: UIPageViewController, UIPageViewControllerDataSource {

lazy var viewControllerList: [UIViewController] = {
    let sb = UIStoryboard(name: "Main", bundle: nil)
    let vc1 = sb.instantiateViewController(withIdentifier: "NavBirdVC")
    let vc2 = sb.instantiateViewController(withIdentifier: "NavChickVC")
    let vc3 = sb.instantiateViewController(withIdentifier: "NavEggVC")
    return [vc1, vc2, vc3]
}()

override func viewDidLoad() {
    super.viewDidLoad()
    self.dataSource = self
    if let firstViewController = viewControllerList.first {
        self.setViewControllers([firstViewController], direction: .forward, animated: true, completion: nil)
    }
}

func pageViewController(_ pageViewController: UIPageViewController, viewControllerBefore viewController: UIViewController) -> UIViewController? {
    guard let vcIndex = viewControllerList.index(of: viewController) else {return nil}
    let previousIndex = vcIndex - 1
    guard previousIndex >= 0 else {return nil}
    guard viewControllerList.count > previousIndex else {return nil}
    return viewControllerList[previousIndex]
}

func pageViewController(_ pageViewController: UIPageViewController, viewControllerAfter viewController: UIViewController) -> UIViewController? {
    guard let vcIndex = viewControllerList.index(of: viewController) else {return nil}
    let nextIndex = vcIndex + 1
    guard viewControllerList.count != nextIndex else {return nil}
    guard viewControllerList.count > nextIndex else {return nil}
    return viewControllerList[nextIndex]
}

}

尾随滑动操作代码：

    override func tableView(_ tableView: UITableView,
                        trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration?
{
    let deleteAction = UIContextualAction(style: .normal, title:  "Delete", handler: { (ac:UIContextualAction, view:UIView, success:(Bool) -> Void) in
        let optionMenu = UIAlertController(title: nil, message: "Weet u zeker dat u dit kuiken wilt verwijderen?", preferredStyle: .actionSheet)
        let delete2Action = UIAlertAction(title: "Verwijder kuiken \(self.araKuikens[indexPath.row].roepNaam)", style: .destructive, handler: {(alert: UIAlertAction!) -> Void in
            self.araKuikens[indexPath.row].deleteItem()
            self.araKuikens.remove(at: indexPath.row)
            tableView.deleteRows(at: [indexPath], with: .automatic)
        })
        let archiveerAction = UIAlertAction(title: "Archiveer kuiken \(self.araKuikens[indexPath.row].roepNaam)", style: .default, handler: {(alert: UIAlertAction!) -> Void in
            var araKuiken = self.araKuikens[indexPath.row]
            araKuiken.markAsCompleted()
            self.araKuikens.remove(at: indexPath.row)
            tableView.deleteRows(at: [indexPath], with: .automatic)
        })
        let cancelAction = UIAlertAction(title: "Annuleer", style: .cancel, handler: {(alert: UIAlertAction!) -> Void in
        })
        optionMenu.addAction(delete2Action)
        optionMenu.addAction(archiveerAction)
        optionMenu.addAction(cancelAction)
        self.present(optionMenu, animated: true, completion: nil)
        success(true)
    })
    let shareAction = UIContextualAction(style: .normal, title:  "Share", handler: { (ac:UIContextualAction, view:UIView, success:(Bool) -> Void) in
        success(true)
    })
    deleteAction.image = UIImage(named: "Trash")
    deleteAction.backgroundColor = .red
    shareAction.image = UIImage(named: "Share")
    shareAction.backgroundColor = .orange
    return UISwipeActionsConfiguration(actions: [deleteAction,shareAction])
}

override func tableView(_ tableView: UITableView,
                        leadingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration?
{
    let weightAction = UIContextualAction(style: .normal, title:  "Gewicht", handler: { (ac:UIContextualAction, view:UIView, success:(Bool) -> Void) in
        self.index = indexPath.row
        self.performSegue(withIdentifier: "weightSegue", sender: ac)
        success(true)
    })
    weightAction.image = UIImage(named: "Scale")
    weightAction.backgroundColor = UIColor(red: 0/255, green: 122/255, blue: 255/255, alpha: 1)
    return UISwipeActionsConfiguration(actions: [weightAction])
}

UIGestureRecognizer有一个名为cancelsTouchesInView的媒体资源。将其设置为false，以便调用两个手势。
