填写表格视图节和单元格

Question

我是Swift的新手程序员，正在为自己做一个项目，但是遇到了一个小问题。我有一个带有枚举的文件来填充表。也是表的类中的扩展。我的问题是我无法在另一个类中用这些枚举填充表格，下面将显示实现代码。

enumsTable.swift

import Foundation
import UIKit

// Section
enum sectionsTable:Int
{
    case sectionTableOne
    case sectionTableTwo

    var titleSectionTable: String {
        switch self {
        case .sectionTableOne:
            return  "titleSectionTableOne"
        case .sectionTableTwo:
            return  "titleSectionTableTwo"
        }
    }
}
// cell in section one
    enum cellSectionOne:Int
    {
        case cellOne
        case cellTwo

    var titleCellSectionOne:String
    {
        switch self {
        case .cellOne:
            return  "cellOne"
        case .cellTwo:
            return  "cellTwo"

        }
    }

}
// icon cell in section one
enum cellIconSectionOne:Int {

    case cellOneIcon
    case cellTwoIcon

    var icon: UIImage {
        switch self {
        case .cellOneIcon:
            return UIImage(named: "iconOne.png")!
        case .cellTwoIcon:
            return UIImage(named: "iconTwo.png")!
        }
    }
}

//cell in section two
enum cellSectionTwo:Int
{
    case cellOne
    case cellTwo

    var titleCellSectionTwo:String
    {
        switch self {
        case .cellOne:
            return  "cellOne"
        case .cellTwo:
            return  "cellTwo"

        }
    }

}
// icon cell in section two
enum cellIconSectionTwo:Int {

    case cellOneIcon
    case cellTwoIcon

    var icon: UIImage {
        switch self {
        case .cellOneIcon:
            return UIImage(named: "iconOne.png")!
        case .cellTwoIcon:
            return UIImage(named: "iconTwo.png")!
        }
    }
}

ViewController.swift

extension ViewController: UITableViewDelegate, UITableViewDataSource
{


    func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
        return // ?
    }

    func numberOfSections(in tableView: UITableView) -> Int {
        return // ?
    }
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return  //?
    }

    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

        let cell = tableView.dequeueReusableCell(withIdentifier: idCell,for: indexPath) as! ViewControllerTableViewCell

        //cellTextLabel ?
        //cellImage ?


        return cell
    }

}

您可以像这样使枚举

    enum Menu: Int, CaseIterable {
    case Home = 0, Mortgage_Calculate
    func description() -> String {
        switch self {
        case .Home:
            return "Home"
        case .Mortgage_Calculate:
            return "Mortgage Calculate"
        }
    }

    func icon() -> String {
        switch self {
        case .Home:
            return "home"
        case .Mortgage_Calculate:
            return "calculator"
        }
    }

    func url() -> String {
        switch self {
        case .Home:
            return ""
        case .Mortgage_Calculate:
            return ""
        }
    }
}

并像这样使用

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
       let cell = tableView.dequeueReusableCell(withIdentifier: "RightSlideTableViewCell", for: indexPath) as! RightSlideTableViewCell
       cell.lbl_title.text = Menu(rawValue: (indexPath.row))?.description()
       let image_name = Menu(rawValue: (indexPath.row))?.icon() ?? ""
       cell.image_item.image = UIImage(named: image_name)
       return cell
   }

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