我试图在覆盖函子tableView（…didSelectRowAt…）中关闭tableViewController，但没有任何反应

Question

I want to return to my previous viewController, so I used the dismiss method, but when I select a cell nothing happens. This is the code that I have right now.

override func tableView(_ tableView: UITableView, didSelectRowAtindexPath: IndexPath) {


            delegate?.dataReceived(data: universityArray[indexPath.row].name)
            dismiss(animated: true, completion: nil)

    }

Answer 1

Form the top of my head, i can see two potential problems here

1. The tableView delegate is not set

tableView.delegate = self

2. The viewController was not presented rather pushed, of that is the case try popViewController instead of dismiss

self.navigationController?.popViewController(animated: true)

Hope the problem was one of the above.
