Swift 如何在tableviewer中显示下一个索引路径行和节项

我尝试从firestore文档中获取数据并显示在tableview单元格中，但有些人认为这只会显示第一行数据。请帮我检查下面的代码，看看哪个部分出错了。非常感谢

enter code here
@IBOutlet weak var ResDateTxt: UITextField!
@IBOutlet weak var ResTableView: UITableView!
@IBOutlet weak var CheckResBtn: UIStackView!

let userDefault = UserDefaults.standard
let resDatePick = UIDatePicker()

var ReservationList = [Reservation]()

override func viewDidLoad() {
    super.viewDidLoad()

    hidKeyBoardWhenTappedAround()
    createDatePicker()
    ResTableView.register(UITableViewCell.self, forCellReuseIdentifier: "ResCell")
    ResTableView.delegate = self
    ResTableView.dataSource = self

    // Do any additional setup after loading the view.
}

@IBAction func CheckResTapped(_ sender: Any) {
    let ResCollectionRef = Firestore.firestore().collection("Reservations").whereField("resDate", isEqualTo: ResDateTxt.text!)
        ResCollectionRef.getDocuments { (snapshot, error) in
        if let err = error {
            debugPrint("Error fetching doc: \(err)")
        } else {
            self.ReservationList = snapshot!.documents.compactMap({Reservation(dictionary: $0.data())})
            print(self.ReservationList)
            DispatchQueue.main.async {
                self.ResTableView.reloadData()
            }
          
        }
    }
}

func createDatePicker() {
    
    ResDateTxt.textAlignment = .center
    //toolbar
    let toolbar = UIToolbar()
    toolbar.sizeToFit()
    
    //bar button
    let doneBtn = UIBarButtonItem(barButtonSystemItem: .done, target: nil, action: #selector(donePressed))
    toolbar.setItems([doneBtn], animated: true)
    
    //assign toolbar
    ResDateTxt.inputAccessoryView = toolbar
    //assign date picker to the text feild
    ResDateTxt.inputView = resDatePick
    
    resDatePick.datePickerMode = .date
    resDatePick.minimumDate = Calendar.current.date(byAdding: .day, value: 0, to: Date())
    resDatePick.maximumDate = Calendar.current.date(byAdding: .month, value: 1, to: Date())
}

@objc func donePressed() {
    let formatter = DateFormatter()
    formatter.dateStyle = .medium
    formatter.timeStyle = .none
    
    ResDateTxt.text = formatter.string(from: resDatePick.date)
    self.view.endEditing(true)
}

}

扩展ResDetailViewController:UITableViewDelegate，UITableViewDataSource{

func numberOfSections(in tableView: UITableView) -> Int {
    return ReservationList.count
}

func tableView（tableView:UITableView，numberofrowsinssection:Int）->Int{ 返回1 }

---

}

您已将功能

numberOfRowsInSection

和

numberOfSections

调高。应该是：

func numberOfSections(in tableView: UITableView) -> Int {
      return 1
}

以及：

---

您已将功能

numberofrowsinssection

和

numberOfSections

切换到较高的级别。应该是：

func numberOfSections(in tableView: UITableView) -> Int {
      return 1
}

以及：

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int { 
        // This is the function that says how many rows in the tableView
        return ReservationList.count
 }
