我正在开发一个应用程序,需要检查作业的截止日期.我想知道截止日期是否在下周内,如果是,则执行操作.
我能找到的大部分文档都在Objective-C中,我无法弄清楚如何在Swift中完成它.谢谢您的帮助!!

我想做的是今天,昨天,本周,本周,本周,本月,上个月变量准备比较要在UITableView的titleForHeaderInSection上添加标题的NSDate

我想要的是在下面的代码中手动完成日期2009-12-11

 NSDate *today = [NSDate dateWithString:@"2009-12-11 00:00:00 +0000"];
 NSDate *yesterday = [NSDate dateWithString:@"2009-12-10 00:00:00 +0000"];
 NSDate *thisWeek = [NSDate dateWithString:@"2009-12-06 00:00:00 +0000"];
 NSDate *lastWeek = [NSDate dateWithString:@"2009-11-30 00:00:00 +0000"];
 NSDate *thisMonth = [NSDate dateWithString:@"2009-12-01 00:00:00 +0000"];
 NSDate *lastMonth = [NSDate dateWithString:@"2009-11-01 00:00:00 +0000"];

我想计算两个NSDates之间的月数和天数.我有正确计算的天数,但如何将其转换为月份和剩余天数？

这就是我用来计算总天数的方法,它正常工作.

- (NSInteger) numberOfDaysUntil {
    NSDate *fromDate;
    NSDate *toDate;

    NSCalendar *calendar = [NSCalendar currentCalendar];

    [calendar rangeOfUnit:NSDayCalendarUnit startDate:&fromDate interval:NULL forDate:[self dateOnly:[NSDate date]]];
    [calendar rangeOfUnit:NSDayCalendarUnit startDate:&toDate interval:NULL forDate:[self dateOnly:self]];

    NSDateComponents *difference = [calendar components:NSDayCalendarUnit fromDate:fromDate toDate:toDate options:0];
    return [difference day];
}
