Swift日历，工作日从周一开始，而不是周日

Question

伙计们，我正在学习一个教程，使用SwiftUI 在我的应用程序中显示日历

一切正常，但我需要：显示从周一开始而不是从周日开始的周的名称并根据一周的第一天更改日期

现在我已经做到了，我该如何实现我的目标？

private extension Calendar {

func generateDates(for interval: DateInterval, matching components: DateComponents) -> [Date] {
var dates = [interval.start]
enumerateDates(startingAfter: interval.start, matching: components, matchingPolicy: .nextTime) { result, _, stop in
guard let date = result else { return }
guard date < interval.end else {
stop = true
return
}
dates.append(date)
}
return dates
}

func generateDays(for interval: DateInterval) -> [Date] {
generateDates(for: interval, matching: dateComponents([.hour, .minute, .second], from: interval.start))
}
}

func makeDays() -> [Date] {
guard let firstWeek = calendar.dateInterval(of: .weekOfMonth, for: selectedDate),
let lastWeek = calendar.dateInterval(of: .weekOfMonth, for: firstWeek.end - 1) else { return [] }
let interval = DateInterval(start: firstWeek.start, end: lastWeek.end)
return calendar.generateDays(for: interval)
}

Answer 1

创建自定义公历并将第一个工作日设置为周一

var customCalendar = Calendar(identifier: .gregorian)
customCalendar.firstWeekday = 2

Answer 2

创建一个列表并替换周数：

return [0,7,1,2,3,4,5,6][Calendar.current.component(.weekday, from: Date())]
// Monday -> 1
// ...
// Sunday -> 7
