当调用模拟器 版本 6.1 的方法时，它显示：
year---2012
week no---52
weekday---2
resultdate---2012-12-16 18:30:00 +0000
日期时间是 2012 年 12 月 17 日到 23 2012 年 12 月
版本 5.0 它显示：
年---2012 年
第 52 个
工作日---2结果日期
---2012-12-23 18:30:00 +0000 日期时间是 12 月 24 日。2012 年至 12 月 30 日 2012

 NSCalendar *gregorian                               = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
gregorian.Locale                                    = [NSLocale currentLocale];
//[gregorian setTimeZone:[NSTimeZone timeZoneWithName:@"GMT"]];
gregorian.firstWeekday                              = 2; // Sunday = 1, Saturday = 7


NSDateComponents *components                        = [gregorian components:NSYearForWeekOfYearCalendarUnit |NSWeekOfYearCalendarUnit |NSWeekdayOrdinalCalendarUnit fromDate:[NSDate date]];

[components setYearForWeekOfYear:2012];
[components setWeekOfYear:52];
[components setWeekdayOrdinal:2];
NSLog(@"year---%ld",(long)[components yearForWeekOfYear]);
NSLog(@"week no---%ld",(long)[components weekOfYear]);
NSLog(@"weekday---%ld",(long)[components weekdayOrdinal]);

NSDate                  *resultDate                 = [gregorian dateFromComponents:components];
NSLog(@"resultdate---%@",resultDate);
NSDate                  *startOfTheWeek;
NSDate                  *endOfWeek;
NSTimeInterval          interval;
[gregorian rangeOfUnit:NSWeekOfYearCalendarUnit startDate:&startOfTheWeek interval:&interval forDate:resultDate];
endOfWeek                                           = [startOfTheWeek dateByAddingTimeInterval:interval-1];

并得到使用的输出日期格式化程序是

NSDateFormatter* dateFormatter          = [[NSDateFormatter alloc] init];
    [dateFormatter setDateFormat:@"dd MMM yyyy"];
    NSString *str_StartOfTheWeek            = [dateFormatter stringFromDate:startOfTheWeek];
    NSString *str_EndOfWeek                 = [dateFormatter stringFromDate:endOfWeek];
    NSLog(@"date time is %@",[NSString stringWithFormat:@"%@ To %@",str_StartOfTheWeek,str_EndOfWeek]);
    return                                 [NSString stringWithFormat:@"%@ To %@",str_StartOfTheWeek,str_EndOfWeek];

如何解决这个问题请帮忙。

要设置工作日（例如 2 = 星期一），您必须使用NSWeekdayCalendarUnitand setWeekday:，而不是NSWeekdayOrdinalCalendarUnitand setWeekdayOrdinal:：

NSDateComponents *components = [gregorian components:NSYearForWeekOfYearCalendarUnit|NSWeekOfYearCalendarUnit|NSWeekdayCalendarUnit
                        fromDate:[NSDate date]];
[components setYearForWeekOfYear:2012];
[components setWeekOfYear:52];
[components setWeekday:2];

通过此修改，输出为

日期时间为 2012 年 12 月 17 日至 2012 年 12 月 23 日

在 iOS 5 和 iOS 6 上。
