iOS怎么判断两个日期在同一周

[p5433251]

NSDate *date = [NSDate date]; NSCalendar*calendar = [NSCalendar currentCalendar]; NSDateComponents *comps = [calendar components:(NSWeekCalendarUnit | NSWeekdayCalendarUnit |NSWeekdayOrdinalCalendarUnit) fromDate:date] NSInteger week = [comps week];

struct DateTime { int year; int month; int day; int weekday; //days since Sunday - [0, 6] int hour; int minute; int second; }; bool IsBetweenOneWeek(DateTime dt1, DateTime dt2) { int diff, weekDay; DateTime LaterDt; if (dt.day < dt2.day) // diff为较早日期减去较晚日期的差值 { diff = dt1.day - dt2.day; } else { diff = dt2.day - dt1.day; } if (abs(diff) > 6) // 相差天数大于6天，必然不在一周内 { return false; } LaterDt = dt1.day > dt2.day ? dt1 : dt2; // 取得较晚的日期 weekDay = LaterDt.weekday; if (((diff + weekDay) < 0) || ((diff + weekDay) > 6)) { return false; } return true; }
