Delegate returns nil and not being called
3
I have an overlay that I want to remove when a button is clicked thereby dismissing the ViewController. I have debugged and the delegate is currently returning nil. I'm not sure what I'm doing wrong here. Have I missed implementing something else? I have even tried out print statements but can't see anything.
protocol DismissOverlayDelegate: class {
func dismissOverlay(_ sender: PlayersViewController)
}
class PlayersViewController: UIViewController {
weak var delegate: DismissOverlayDelegate?
@IBAction func getStartedTapped(_ sender: UIButton) {
self.delegate?.dismissOverlay(self)
}
}
and in my ViewController where I implement the delegate method
class HomeViewController: UIViewController, DismissOverlayDelegate {
@IBOutlet weak var customOverlay: CustomOverlayView!
let playersViewController = PlayersViewController()
override func viewDidLoad() {
super.viewDidLoad()
self.playersViewController.delegate = self
}
func dismissOverlay(_ sender: PlayersViewController) {
self.customOverlay.removeFromView()
}
}
delegate = (DismissOverlayDelegate?) nil
The PlayersViewController is embedded into a UIPageViewController
class HomeViewController: UIPageViewController, UIPageViewControllerDataSource {
var pages = [UIViewController]()
override func viewDidLoad() {
super.viewDidLoad()
for storyboardIDs in ["playersVC1","playersVC2"] {
let viewController = self.storyboard?.instantiateViewController(withIdentifier: storyboardIDs)
self.pages.append(viewController!)
}
self.dataSource = self
self.setViewControllers([self.pages.first!], direction: .forward, animated: true)
}
func pageViewController(_ pageViewController: UIPageViewController, viewControllerBefore viewController: UIViewController) -> UIViewController? {
let currentIndex = self.pages.firstIndex(of: viewController)!
if currentIndex > 0 {
return self.pages[currentIndex - 1]
}
return nil
}
func pageViewController(_ pageViewController: UIPageViewController, viewControllerAfter viewController: UIViewController) -> UIViewController? {
let currentIndex = self.pages.firstIndex(of: viewController)!
if currentIndex < (self.pages.count - 1) {
return self.pages[currentIndex + 1]
}
return nil
}
}

your instanceplayersViewControlleris not the instance that is on-screen, you need to get hold of the actual instance in the view controller stack. You cannot just create an instance usingPlayersViewController().

Let me explain you if you are using or want to use delegate for call or implement something there is root and you have to that on a right way. You are doing well no issue but the implementation of delegate is not properly your method can't accept that so try this:-
Your Home View Controller
class HomeViewController: UIViewController, DismissOverlayDelegate {
@IBOutlet weak var customOverlay: UIView!
override func viewDidLoad() {
super.viewDidLoad()
}
func dismissOverlay(_ sender: PlayersViewController) {
self.customOverlay.removeFromSuperview()
}
@IBAction func go(_ sender: UIButton) {
let vc = self.storyboard?.instantiateViewController(withIdentifier: "PlayersViewController") as! PlayersViewController
vc.delegate = self
self.navigationController?.pushViewController(vc, animated: true);
}
}
this is your playground VC
protocol DismissOverlayDelegate: class {
func dismissOverlay(_ sender: PlayersViewController)
}
class PlayersViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
weak var delegate: DismissOverlayDelegate?
@IBAction func getStartedTapped(_ sender: UIButton) {
self.delegate?.dismissOverlay(self)
}
}
now hope you understand what you have to do...!

Let me explain you if you are using or want to use delegate for call or implement something there is root and you have to that on a right way. You are doing well no issue but the implementation of delegate is not properly your method can't accept that so try this:-
Your Home View Controller
class HomeViewController: UIViewController, DismissOverlayDelegate {
@IBOutlet weak var customOverlay: UIView!
override func viewDidLoad() {
super.viewDidLoad()
}
func dismissOverlay(_ sender: PlayersViewController) {
self.customOverlay.removeFromSuperview()
}
@IBAction func go(_ sender: UIButton) {
let vc = self.storyboard?.instantiateViewController(withIdentifier: "PlayersViewController") as! PlayersViewController
vc.delegate = self
self.navigationController?.pushViewController(vc, animated: true);
}
}
this is your playground VC
protocol DismissOverlayDelegate: class {
func dismissOverlay(_ sender: PlayersViewController)
}
class PlayersViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
weak var delegate: DismissOverlayDelegate?
@IBAction func getStartedTapped(_ sender: UIButton) {
self.delegate?.dismissOverlay(self)
}
}
now hope you understand what you have to do...!
