ios - 如何在CollectionView中快速设置从周一到周六的工作日日期

Question

我必须在 CollectionView 中显示从周一到周六的工作日日期。在本周末之前，我必须仅显示工作日日期。我的任务图片Image 。请帮助/建议我如何完成这项任务。

我正在获取工作日，但从当天开始，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
}
