我有这个字符串，它被传递给这个方法以产生 2 次：

周一至周五上午 7:00 - 晚上 10:00

我使用这段代码将字符串分成两次；开闭时间：

-(void)dealWithTimeStrings2:(NSString*)timeString{
    <...IRRELEVANT CODE PARSING STRING INTO DATES...>

    NSLog(@"openDate hours %@, openDate minutes %@", openHours, openMinutes);
    NSLog(@"closeDate hours %@, closeDate minutes %@", closeHours, closeMinutes);
    NSLog(@"nowDate hours %@, nowDate minutes %@", nowHours, nowMinutes);

    //COMPARE HOURS
    if ([openHours intValue] < [nowHours intValue] < [closeHours intValue]) {
        NSLog(@"ABIERTO-dateComponents");
    } else {
        NSLog(@"CERRADO-dateComponents");
    }

    NSLog(@"open, now, close %@,%@,%@", openDate,[NSDate date], closeDate);


    if ([self timeCompare:openDate until:closeDate]) {
        NSLog(@"OPEN-timeCompare");
    } else {
        NSLog(@"CLOSED-timeCompare");
    }
}

这会在控制台中生成这些日志：

someDateString 7:00 AM,10:00 PM  
openDate hours 13, openDate minutes 00 
closeDate hours 04, closeDate minutes 00  
nowDate hours 14, nowDate minutes 51  
OPEN-dateComponents  
open, now, close 2000-01-01 13:00:00 +0000,2013-07-25 14:51:16 +0000,2000-01-02 04:00:00 +0000 2013-07-25 08:51:16:486  
CLOSED-timeCompare

我现在想测试现在时间是否介于开盘时间和收盘时间之间。但是，如果您注意到，打开和关闭时间是在 2000-01-01 和 2000-01-02 年，而现在是在 2013-07-24 年。这是测试代码：

-(BOOL)timeCompare:(NSDate*)date1 until:(NSDate*)date2{
    NSCalendar *calendar = [[NSCalendar alloc]
                            initWithCalendarIdentifier:NSGregorianCalendar];
    NSDateComponents *components =
    [calendar components:(NSHourCalendarUnit | NSMinuteCalendarUnit | NSSecondCalendarUnit) fromDate:[NSDate date]];
    NSDate *date = [calendar dateFromComponents:components];

    return ([date compare:date1] == NSOrderedDescending && [date compare:date2] == NSOrderedAscending);
}

是否因为日期部分而失败？开放日期和结束日期与现在日期不同的事实是什么？
