My app uses a PageViewController, 3 NavigationControllers and 3 ViewControllers. You can swipe from one VC to another. See animated gif.
In the VC's there are TableViews with leading and trailingSwipeActions. To my regret the leading swipe action works only on the first VC. The trailing swipe action only works on the last VC.
A solution would be if the swipe of the PageViewController only works in the area of the picture, and not in the area of the tableviews.
For the leading and trailing swipe action, just a small movement is sufficient. For the PageViewController swipe it must be a big movement. I don't know if that is something to proceed.
Found a lot of questions and some examples, but I can't get them to work on my use case.
The code of the PageViewController:
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]
}
}

The trailing swipe action code:
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])
}
