  您可以使用DateFormatter将特定日期的星期几作为字符串 . 您还可以使用NSDateComponents获取表示星期几的整数值 .

  看到这个SO帖子和答案......

  您也可以（但我不确定它是否更好）从日历中获取工作日组件和名称 .

  NSDate *yourDate     = [NSDate date];
  NSCalendar *calendar = [NSCalendar currentCalendar];
  NSDateComponents *weekdayComponent = 
      [calendar components:NSWeekdayCalendarUnit
                                      fromDate:yourDate];
  
  NSString *dayName = calendar.weekdaySymbols[weekdayComponent.weekday-1];
  
  NSLog(@"today is %@", dayName); // Output: today is Thursday
