如何在集合视图中从周一到周六快速设置工作日日期

Question

我必须从星期一到星期六在 CollectionView 中显示工作日日期。直到周末，我只需要显示工作日的日期。我的任务图片Image。请帮助/建议我如何完成这项任务。

我得到工作日，但它从当天开始，但我需要从星期一开始日期，

func arrayOfDates() -> NSArray {

        let numberOfDays: Int = 6
        let formatter: DateFormatter = DateFormatter()
        formatter.dateFormat = "dd"
        let startDate = Date()
        let calendar = Calendar.current
        var offset = DateComponents()
        var dates: [Any] = [formatter.string(from: startDate)]

        for i in 1..<numberOfDays {
            offset.day = i
            let nextDay: Date? = calendar.date(byAdding: offset, to: startDate)
            let nextDayString = formatter.string(from: nextDay!)
            dates.append(nextDayString)
        }
        return dates as NSArray
    }

试试这个

func formattedDaysInThisWeekNet() -> [String]
{
    // create calendar
    let calendar = NSCalendar(identifier: NSCalendar.Identifier.gregorian)!

    // today's date
    let today = NSDate()

    let weekday = calendar.component(.weekday, from: today as Date)
    let beginningOfWeek : NSDate
    if weekday != 2 { // if today is not Monday, get back
        beginningOfWeek = calendar.nextDate(after: today as Date, matching: .weekday, value: 1, options: [.matchNextTime, .searchBackwards])! as NSDate
    } else { // today is Monday
        beginningOfWeek = calendar.startOfDay(for: today as Date) as NSDate
    }
    var formattedDays = [String]()
    for i in 0..<7 {
        let date = calendar.date(byAdding: .day, value: i, to: beginningOfWeek as Date, options: [])!
        formattedDays.append(formatDate(date: date as NSDate))
        let firstDate = calendar.date(byAdding: .day, value: 0, to: beginningOfWeek as Date, options: [])!
        let lastDate = calendar.date(byAdding: .day, value: 6, to: beginningOfWeek as Date, options: [])!
        let fullString = "\(formatDateFull(date: firstDate as NSDate)) - \(formatDateFull(date: lastDate as NSDate))" as String
        fulldateLbl.text = "<  \(fullString)  >"
        print(fullString)
    }
    return formattedDays
}

enum Days: Int {
    case Sat = 0, Sun, Mon, Tue, Wed, Thu, Fri
    static var all = [Mon, Tue, Wed, Thu, Fri, Sat]
}

func getWeekDays(date: Date) -> [Date] {
    var weekDates = [Date]()

    let cal = Calendar.current
    var comps = cal.dateComponents([.weekOfYear, .yearForWeekOfYear], from: date)
    let days = Days.all
    for day in days {
        comps.weekday = day.rawValue
        weekDates.append(cal.date(from: comps)!)
    }
    return weekDates
}

    print(getWeekDays(date: Date()))  // print all dates from Monday to Saturday

大家好，感谢您的回复。我完成了这个任务。

func arrayOfDates() -> NSArray {

    var calendar = Calendar(identifier: Calendar.Identifier.gregorian)
    let today = calendar.startOfDay(for: Date())
    let dayOfWeek = calendar.component(.weekday, from: today) - calendar.firstWeekday
    let weekdays = calendar.range(of: .weekday, in: .weekOfYear, for: today)!
    let dayss = (weekdays.lowerBound ..< weekdays.upperBound)
        .compactMap { calendar.date(byAdding: .day, value: $0 - dayOfWeek, to: today) }
    //.filter { !calendar.isDateInWeekend($0) }

    let formatter = DateFormatter()
    formatter.dateFormat = "dd"

    let strings = dayss.map { formatter.string(from: $0) }
    self.dates = strings as NSArray
    return dates as NSArray
}

但是在这里我有一个问题，如何禁用以前的日期。我只需要选择当前日期和下一个日期。
