Question

正如标题一样，我正在寻找一个解决方案，包括在工作日添加开放和关闭时间。

图片myApp：

View after selecting the day of the week, (View add hours)

代码：

import UIKit
import CoreData

class OpeningHoursInfoController: UITableViewController, AddDayHouerControllerDelegate {

    let daysOfWeek = ["Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday"]
    var keyCell = "celllllId"
    var hoursArray = [HourInfo]()


    override func viewDidLoad() {
        super.viewDidLoad()

        fetchOpenAndCloseHour()

        tableView.separatorStyle = .singleLine
        tableView.separatorColor = .lightGold
        tableView.tableFooterView = UIView()
        tableView.register(OpeningHoursInfoCell.self, forCellReuseIdentifier: keyCell)
    }

    private func fetchOpenAndCloseHour() {

        let context = CoreDataManager.shared.persistentContainer.viewContext
        let fetchRequest = NSFetchRequest<HourInfo>(entityName: "HourInfo")

        do {

            let hours = try context.fetch(fetchRequest)

            hours.forEach({ (houers) in

            })

            self.hoursArray = hours
            self.tableView.reloadData()

        } catch let fetchErr {
            print("Failed to fetch error in CoreData:", fetchErr)
        }
    }

    override func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
        return 60
    }

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

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

        let cell = tableView.dequeueReusableCell(withIdentifier: keyCell, for: indexPath) as! OpeningHoursInfoCell

        let days = daysOfWeek[indexPath.row]
        cell.textLabel?.text = days
        cell.textLabel?.textColor = .white

        return cell
    }

    override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {

        let day = self.daysOfWeek[indexPath.row]
        let addDayHouersController = AddDayHouerController()
        addDayHouersController.delegate = self
        addDayHouersController.navigationItem.title = day
        navigationController?.pushViewController(addDayHouersController, animated: true)
    }

    // MARK: - AddDayHouerControllerDelegate Methods

    func didAddHour(hour: HourInfo) {

        hoursArray.append(hour)
        let row = hoursArray.index(of: hour)
        let reloadIndexPath = IndexPath(row: row!, section: 0)
        tableView.reloadRows(at: [reloadIndexPath], with: .middle)
    }


}

Code AddDayHouerController：

import UIKit
import CoreData

protocol AddDayHouerControllerDelegate {
    func didAddHour(hour: HourInfo)
}

class AddDayHouerController: UIViewController {

    var delegate: AddDayHouerControllerDelegate?

    // MARK: - Widok
    override func viewDidLoad() {
        super.viewDidLoad()

        // Przycisk NavBar
        navigationItem.rightBarButtonItem = UIBarButtonItem(title: "Save", style: .plain, t
    }

    @objc func handleSave() {

        let context = CoreDataManager.shared.persistentContainer.viewContext
        let hourInfo = NSEntityDescription.insertNewObject(forEntityName: "HourInfo", into: context)

        hourInfo.setValue(hourFrom, forKey: "openHour")
        hourInfo.setValue(hourTo, forKey: "closeHour")

        do {
            try context.save()

            dismiss(animated: true, completion: {
                self.delegate?.didAddHour(hour: hourInfo as! HourInfo)
            })

        } catch let errSave {
            print("Failed to save CoreData:", errSave)
        }

    }

    // Picker View Target
    @objc func handleAddHour(button: UIButton) {

        view.layoutIfNeeded()
        UIView.animate(withDuration: 0.25, animations: {

            self.view.layoutIfNeeded()

        }) { (completed) in

            UIView.animate(withDuration: 0.25, animations: {

                self.timePickerView.alpha = 1
                self.timePickerView.tag = button.tag
                self.view.layoutIfNeeded()
            })
        }
    }

    let timePickerView: UIDatePicker = {
        let pv = UIDatePicker()
        pv.timeZone = .current
        pv.datePickerMode = .time
        pv.addTarget(self, action: #selector(handleChoiceTime), for: .valueChanged)
        return pv
    }()

    var hourFrom = ""
    var hourTo = ""
    @objc func handleChoiceTime(sender: UIDatePicker) {

        let formatter = DateFormatter()
        formatter.timeStyle = .short
        let selectedTime = formatter.string(from: sender.date)

        if timePickerView.tag == 0 {
            openFromTimeButton.setTitle(selectedTime, for: .normal)
            hourFrom = selectedTime
            print(hourFrom)
        } else {
            openToTimeButton.setTitle(selectedTime, for: .normal)
            hourTo = selectedTime
            print(hourTo)
        }

        timePickerView.alpha = 0
    }
    }()


    }

} // End class

如何实现这种效果？（例如 - ＆＃34;星期一：上午9:00 - 下午5:00＆＃34;）

Answer 1

您需要一个合适的数据模型，例如一个类来获取引用语义

class DayOfWeek {
    let name : String 
    var openHour : Date?
    var closeHour : Date?

    init(name : String) {
         self.name = name
    }
}

然后创建数据源数组

let daysOfWeek = [DayOfWeek(name:"Monday"), 
                  DayOfWeek(name:"Tuesday"), 
                  DayOfWeek(name:"Wednesday"), 
                  DayOfWeek(name:"Thursday"), 
                  DayOfWeek(name:"Friday"), 
                  DayOfWeek(name:"Saturday"), 
                  DayOfWeek(name:"Sunday")]

而不是hoursArray使用类中的Date属性或声明类

class DayOfWeek {
    let name : String 
    var hourInfo : HourInfo?

    init(name : String) {
         self.name = name
    }
}

在cellForRow中分配name

    let currentDay = daysOfWeek[indexPath.row]
    cell.textLabel?.text = currentDay.name

当呈现AddDayHouerController时，将相应索引路径的实例传递给控制器并设置小时数。由于引用语义（此实例和数据源数组中的实例指向同一对象），您不需要将更改的项目传回。

注意：为什么要注册OpeningHoursInfoCell？如果单元格是在Interface Builder的表格视图中设计的，并且您没有使用额外的XIB，则不能注册该单元格。
