viewWillDisapper isn't called when opening a second view with popOver

On my mainVC I have a TableView with a button that should open the secondVC, where I can add things to show then in the Table, with the kind: "Present As Popover".

I'm opening the secondVC with performSegue(withIdentifier:"goToOtherView", sender: nil.

class FirstViewController: UIViewController {
    
    @IBOutlet weak var tableView: UITableView!
    
    var groupData = ["Data, Data1, Data2"]

    override func viewDidLoad() {
        super.viewDidLoad()
        
        view.backgroundColor = .green
        
        tableView.delegate = self
        tableView.dataSource = self
        
    }

    @IBAction func btnTapped(_ sender: Any) {
        
        performSegue(withIdentifier: "goToOtherView", sender: nil)
    }
    
    override func viewWillAppear(_ animated: Bool) {
        print("FirstViewController will appear")
    }
    
    override func viewDidAppear(_ animated: Bool) {
        print("FirstViewController did appear")
    }
    
    override func viewWillDisappear(_ animated: Bool) {
        print("FirstViewController will disappear")
    }
    
    override func viewDidDisappear(_ animated: Bool) {
        print("FirstViewController did disappear")
    }
    
}

class SecondViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        
        view.backgroundColor = .blue

    }
    
    override func viewWillAppear(_ animated: Bool) {
        print("SecoundViewController will appear")
    }
    
    override func viewDidAppear(_ animated: Bool) {
        print("SecoundViewController did appear")
    }
    
    override func viewWillDisappear(_ animated: Bool) {
        print("SecoundViewController will disappear")
    }
    
    override func viewDidDisappear(_ animated: Bool) {
        print("SecoundViewController did disappear")
    }
    
}

When I open the secondVC When I open the secondVC

And when I close the secondVC enter image description here

The FirstViewController willDisappear and didDisappear are never being called, or even when the secondVC is closed the willAppear and didAppear. I want to call the function tableView.reloadData() when the FirstView willAppear/didAppear

It's kinda the same like the IOS default clock app, when you add a new alarm clock.

Solution

  • Quick guess, but I think that’s because of the presentation mode being pageSheet

    Can you try to change it to fullScreen?

    You can also change your segue configuration to be like: enter image description here

    View disappear won't be called since the view does not completely disappears from the window
