Question

我在VC中有tableview，我想从当前食谱中导入“Detail”项目：

到tableView - 每个到一个单独的单元格。

我在RecipiesModel中的代码：

class RecipiesModel {

    var title: String?
    var desc: String?
    var detail: Array<Any>?

    init(title: String?, desc: String?, detail: Array<Any>?){
        self.title = title
        self.desc = desc
        self.detail = detail
    }
}

我在VC中的代码：

import UIKit
import FirebaseDatabase

class DescriptionViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {

    var textInput: String = ""
    var descInput: String = ""

    var ref:DatabaseReference!
    var recipiesList = [RecipiesModel]()

    @IBOutlet weak var tableView: UITableView!
    @IBOutlet weak var titleLabelDesc: UILabel!
    @IBOutlet weak var descriptionLabelDesc: UILabel!
    @IBOutlet weak var imageView: UIImageView!
    @IBOutlet weak var tabBarView: UIView!

    override func viewDidLoad() {
        super.viewDidLoad()
        UIApplication.shared.statusBarStyle = .lightContent

        tableView.delegate = self
        tableView.dataSource = self

        customUIView()

        titleLabelDesc.text = textInput
        descriptionLabelDesc.text = descInput

        loadList()
    }

    //Database

    func loadList() {
        ref = Database.database().reference()
        ref.child("Recipies").observe(.childAdded, with: { (snapshot) in
            let results = snapshot.value as? [String : AnyObject]
            let title = results?["Recipies title"]
            let desc = results?["Recipies description"]
            let detail = results?["Detail"]
            let myRecipies = RecipiesModel(title: title as! String?, desc: desc as! String?, detail: detail as! Array<Any>?)
            self.recipiesList.append(myRecipies)

            DispatchQueue.main.async {
                self.tableView.reloadData()
            }
        })
    }

    func customUIView() {
        tabBarView.layer.shadowColor = UIColor.lightGray.cgColor
        tabBarView.layer.shadowOpacity = 1
        tabBarView.layer.shadowOffset = CGSize.zero
        tabBarView.layer.shadowRadius = 3
    }

    @IBAction func dismissButton(_ sender: Any) {
        dismiss(animated: true, completion: nil)
    }

    //TableView

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

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

    public func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "cellDescription") as! TableViewCellDescription

        let recipies = recipiesList[indexPath.row]
        cell.recipiesModuleLabel.text = recipies.detail?.description

        return cell
    }
}

此时结果是：

Table View Entries

有什么想法吗？

Answer 1

在您的情况下，您希望在不同的行中显示详细信息，而您有var recipiesList = [RecipiesModel]()的数组。

modal object of array

如果您可以将每个details表示为一个部分，并将// TableView datasource and delegate methods func numberOfSections(in tableView: UITableView) -> Int { return recipiesList.count } func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? { let modal = recipiesList[section] return "\(modal.title ?? ""): \(modal.desc ?? "")" } func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int { return recipiesList[section].detail?.count ?? 0 } func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { let cell = tableView.dequeueReusableCell(withIdentifier: "cellDescription") as! TableViewCellDescription if let detailName = recipiesList[indexPath.section].detail?[indexPath.row] as? String { cell.recipiesModuleLabel.text = detailName } else { cell.recipiesModuleLabel.text = "" } return cell }个对象表示为其行。你可以这样做：

Firebase将数组导入数据到tableview
