如何在单击UIViewTableCell时执行segue？

Question

当我单击一个UITableViewCell时，我在情节提要中已经有一个从UITableView到下一个视图控制器的切换？有人告诉我要使用'did selectrowat'功能，但似乎无法让它工作！

我试图访问的视图控制器被称为“VendorHome”，它来自的控制器被称为“Home controller”。如果有用的话，UITableView，UITableCellView和content UIView是无类的。

import UIKit
import Firebase

class HomeController: UIViewController, UITableViewDelegate, UITableViewDataSource {

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath){
    tableView.deselectRow(at: indexPath, animated: true)
    performSegue(withIdentifier: "HomeCellToVendorPage", sender: self)
}




func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return DataCellLabels.count
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell{
    let cell = HomeTableView.dequeueReusableCell(withIdentifier: "HomeCell", for: indexPath)
    as! HomeCell
    cell.UsernameLabel.text = DataCellLabels[indexPath.row].Title
    cell.DistanceLabel.text = DataCellLabels[indexPath.row].Distance
    cell.StarRatingLabel.text = DataCellLabels[indexPath.row].Rating
    cell.AvailabilityLabel.text = DataCellLabels[indexPath.row].Avaliability
    

    return cell
}

let db = Firestore.firestore()

var DataCellLabels: [CellLabel] = []

@IBOutlet weak var HomeTableView: UITableView!



override func viewDidLoad() {
    super.viewDidLoad()


    // Do any additional setup after loading the view.
    
    HomeTableView.dataSource = self
    
    
    HomeTableView.register(UINib(nibName: "HomeCell", bundle: nil), forCellReuseIdentifier: "HomeCell")
    
    LoadHomeCells()
}

func LoadHomeCells() {
    DataCellLabels = []
    
    db.collection("users").getDocuments { (QuerySnapshot, error) in
        if let e = error {
            print ("Error \(e)")
        } else {
            if let snapshotDocuments = QuerySnapshot?.documents {
                for doc in snapshotDocuments {
                    let data = doc.data()
                    if let CellTitle = data["Username"] as? String , let CellDistance = data["Distance"] as? String, let CellRating = data["Rating"] as? String, let CellAvaliability = data["Avaliability"] as? String {
                        let NewCell = CellLabel(Title: CellTitle, Distance: CellDistance, Rating: CellRating ,Avaliability: CellAvaliability)
                        self.DataCellLabels.append(NewCell)
                        
                        DispatchQueue.main.async {
                            self.HomeTableView.reloadData()
                        }
                    }
                }
            }
        }
    }
}

}

Answer 1

忘记添加委托:

HomeTableView.delegate = self

Answer 2

看起来您只设置了数据源，您还需要设置表视图委托。

HomeTableView.delegate = self

DidSelectroWatIndex是UITableViewDelegate方法，而不是datasource方法
