如何在JTCalendar中获取包含年份的月份名称？

Question

我正在使用JTCalendar。我想知道显示哪个日历的月份。截至目前，日历中没有显示月份名称。我用下面的代码来显示日历。

  calendarManager = JTCalendarManager()
  calendarManager?.delegate = self
  var calender = calendarManager?.dateHelper.calendar()
  calender?.firstWeekday = 1
  calendarManager?.contentView = calendarContentView
  calendarManager?.setDate(todayDate)

请指导我如何用年份显示月份名称。

Answer 1

只需将月份的UIView类设置为“JTCalendarMenuView”，然后就可以使用JTCalendarDelegate方法：

    - (UIView *)calendarBuildMenuItemView:(JTCalendarManager *)calendar
{
    UILabel *label = [UILabel new];

    label.textAlignment = NSTextAlignmentCenter;
    label.font = [UIFont systemFontOfSize:16];

    return label;
}

- (void)calendar:(JTCalendarManager *)calendar prepareMenuItemView:(UILabel *)menuItemView date:(NSDate *)date
{
    static NSDateFormatter *dateFormatter;
    if(!dateFormatter){
        dateFormatter = [NSDateFormatter new];
        dateFormatter.dateFormat = @"MMMM yyyy";
    }
    menuItemView.text = [dateFormatter stringFromDate:date];
}

这将为您提供“2016年12月”的文字（例如）

除了@ Aakash的回答，menuItemView实际上是一个UIView。所以它没有.text属性。而是使用这一行，[（UILabel *）menuItemView setText：[dateFormatter stringFromDate：date]];

只需添加此功能。

   func calendar(_ calendar: JTCalendarManager!, prepareMenuItemView menuItemView: UIView!, date: Date!) {
    for view in menuItemView.subviews {
        view.removeFromSuperview()
    }
    let label1 = UILabel(frame: CGRect(x: 80, y: 60, width:400, height: 21))
    label1.center = CGPoint(x: 130, y: 20)
    label1.textColor = UIColor.red
    label1.textAlignment = NSTextAlignment.center
    let dateFormatter1 = DateFormatter()
    dateFormatter1.dateFormat = "MMMM, yyyy";
    let mydt = dateFormatter1.string(from: date)
    label1.text = mydt
    menuItemView.addSubview(label1)
}

Swift 4+：

简单解决方案

var getMonthYearFromDate: String? 
{
     let dateFormatter = DateFormatter()
     dateFormatter.dateFormat = "MMMM, yyyy"
     let strMonth = dateFormatter.string(from: self)
     return strMonth
}

func calendar(_ calendar: JTCalendarManager!, prepareMenuItemView menuItemView: UIView!, date: Date!) 
{
     print(date.getMonthYearFromDate)
