Delegete in table view cell

Question

I have a table on which a cell is made using .xib. There are two views on this cell. When I click on each view, and I set the image and title for another viewController. I made a protocol for this, but I just can’t get this data on another viewController because my delegate = nil.

In this class, I set properties.

сlass DataTableViewCell: UITableViewCell {

var dataDelegete: DataAccountCellDelegete? = nil

 @objc func accountViewTaped() {
        dataDelegete?.navigationBarIcon(image: UIImage(named: "icon") ?? UIImage())
        dataDelegete?.navigationBarTitle(title: "title")
        
        
    }
    @objc func settingsViewTaped() {
        dataDelegete?.navigationBarIcon(image: UIImage(named: "icon") ?? UIImage())
        dataDelegete?.navigationBarTitle(title: "title")
    }
    
}
protocol DataAccountCellDelegete {
    func navigationBarIcon(image: UIImage)
    func navigationBarTitle(title: String)

}

In this class, I get and want to set these properties, but my delegate = nil

class AccountViewController: UIViewController {

var dataVC =  DataTableViewCell()

    override func viewDidLoad() {
        super.viewDidLoad()
        
       dataVC.delegete = self   
    }
}
extension AccountViewController: DataAccountCellDelegete{
    func menuNavigationBarIcon(image: UIImage) {
      menuNavigationBar.addImage(image)
    }
    
    func menuNavigationBarTitle(title: String) {
        menuNavigationBar.addTitle(title)
    }
}

How do I declare a delegate correctly?

Answer 1

The view hierarchy should be like

ViewController -> TableView -> TableViewCell

So, ViewController has the reference of TableView & TableView has the reference of the cell. So the data passing should be reversed.

TableViewCell -> TableView -> ViewController

as vadian said ,Cells are reused and being created in cellForRowAt. The variable dataVC is useless here.
