我试图弄清楚检查我的约会时间是否在两个其他日期时间之间的方式，例如我从我的服务器获得当前时间为“2015年3月16日14:17”所以我想检查这个日期时间是否是其中两个日期时间范围为“2015年2月4日08：00-09：00” .

    如果您有三个 NSDate 实例，请尝试该代码：

    NSDate *beginDate, *endDate, *checkDate;
if ([beginDate laterDate:checkDate] == checkDate &&
    [checkDate laterDate:endDate] == endDate) {
    //checkDate in between beginDate and endDate
}

    对于日期解析，请使用以下内容：

    NSString *inputRange = @"Feb 4 2015 08:00-09:00";
NSRange firstRange = NSMakeRange(0, inputRange.length - 6);
NSString *firstDate = [inputRange substringWithRange:firstRange];
NSDateFormatter *dateFormatter = [NSDateFormatter new];
dateFormatter.dateFormat = @"MMM dd yyyy HH:mm";
NSDate *beginDate = [dateFormatter dateFromString:firstDate];
NSString *secondDate = [inputRange substringWithRange:NSMakeRange(0, inputRange.length - 11)];
secondDate = [secondDate stringByAppendingString:[inputRange substringWithRange:NSMakeRange(inputRange.length - 5, 5)]];
NSDate *endDate = [dateFormatter dateFromString:secondDate];

    我会建议以下类方法

    + (BOOL)checkDate:(NSDate*)dateToCheck startingDate:(NSDate*)startingDate endDate:(NSDate*)endDate
{
    BOOL returnValue;

    if ([startingDate compare:endDate]==NSOrderedDescending)
    {
        returnValue = [dateToCheck compare:endDate]==NSOrderedAscending && [dateToCheck compare:startingDate]==NSOrderedDescending;

    }
    else if ([startingDate compare:endDate]==NSOrderedAscending)
    {
        returnValue = [dateToCheck compare:startingDate]==NSOrderedAscending && [dateToCheck compare:endDate]==NSOrderedDescending;
    }
    else
    {
    returnValue = [dateToCheck compare:startingDate]==NSOrderedSame && [dateToCheck compare:endDate]==NSOrderedSame;
    }
    return returnValue;
}

    Current date :

    NSDate *currentDate = [NSDate date];

NSLog(@"-- %@",currentDate);

    Start date :

    //开课日期 - 2015-03-12 00:00:58 0000

    NSString *stringStartDate = @"2015-03-12 00:00:58";
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:@"yyyy-MM-dd hh:mm:ss"];
NSDate *dateStart = [formatter dateFromString:stringStartDate];

    End date :

    //结束日期 - 2015-03-20 00:00:58 0000

    NSString *stringEndDate = @"2015-03-20 00:00:58";
NSDateFormatter *formatter1 = [[NSDateFormatter alloc] init];
[formatter1 setDateFormat:@"yyyy-MM-dd hh:mm:ss"];
NSDate *dateEnd = [formatter1 dateFromString:stringEndDate];

    Function to check date between two date or not

    BOOL isDateCheck = [self isDate:currentDate inRangeFirstDate:dateStart lastDate:dateEnd];

    Function

    - (BOOL)isDate:(NSDate *)date inRangeFirstDate:(NSDate *)firstDate lastDate:(NSDate *)lastDate {
    return [date compare:firstDate] == NSOrderedDescending &&
    [date compare:lastDate]  == NSOrderedAscending;
}
