JTAppleCalendar Swift For循环

Question

当您滚动日历时，我使用以下函数尝试为每个标题打印出一个月。我做for循环的方式肯定有问题，因为我唯一退出的月份是12月。有什么想法吗？谢谢

有了print("(names)")，我可以在控制台上打印出所有的月份。但是，我无法在视觉上将它们正确打印出来。

func calendar(_ calendar: JTAppleCalendarView, willDisplaySectionHeader header: JTAppleHeaderView, range: (start: Date, end: Date), identifier: String) {

        //let months: [String] = ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"]
        let months = Calendar.current.monthSymbols
        let headerCell = (header as? MonthsHeader)
        for names in months {
            print("\(names)")
        headerCell?.monthsHeader.text = names

        }
    }

下面是你如何做到这一点。

func calendar(_ calendar: JTAppleCalendarView, willDisplaySectionHeader header: JTAppleHeaderView, range: (start: Date, end: Date), identifier: String) {
   let startDate = range.start
   let month = myCalendar.dateComponents([.month], from: startDate).month!
   let monthName = DateFormatter().monthSymbols[(month-1) % 12]
   let year = testCalendar.component(.year, from: startDate)
   let headerCell = header as? MyHeaderView
   headerCell?.title.text = monthName + " " + String(year)
}

myCalendar -->这是一个Calendar()实例

MyHeaderView->这是header类
