封装用于解析NSDate的便利的类

封装用于解析NSDate的便利的类

此类可以从NSDate中解析出年份，月份，日期，时，分，秒，毫秒，足够用来做好多事情了，现提供源码如下：

以下是核心的类：

TimeInfo.h 与 TimeInfo.m

static NSDateFormatter   *_dateFormatter;

@implementation TimeInfo

+ (void)initialize {

    if (self == [TimeInfo class]) {

        _dateFormatter            = [[NSDateFormatter alloc] init];

        _dateFormatter.locale     = [[NSLocale alloc] initWithLocaleIdentifier:@"en_GB"];

        _dateFormatter.timeZone   = [NSTimeZone timeZoneWithName:@"GMT"];

        _dateFormatter.dateFormat = @"yyyy:MM:dd:MMM:MMMM:HH:mm:ss:aa:EEE:EEEE:SSS"; // SSSS

    }

}

+ (HumanTimeInfo *)humanCanUnderstandFromDate:(NSDate *)date {

    if (date != nil) {

        NSArray *timeInfoArray = [[_dateFormatter stringFromDate:date] componentsSeparatedByString:@":"];

        HumanTimeInfo *info    = [HumanTimeInfo new];

        info.year              = timeInfoArray[];

        info.mounth            = timeInfoArray[];

        info.day               = timeInfoArray[];

        info.enMounth          = timeInfoArray[];

        info.fullEnMounth      = timeInfoArray[];

        info.hour              = timeInfoArray[];

        info.min               = timeInfoArray[];

        info.sec               = timeInfoArray[];

        info.amPm              = timeInfoArray[];

        info.enWeakday         = timeInfoArray[];

        info.fullWeakday       = timeInfoArray[];

        info.mSec              = timeInfoArray[];

        return info;

    } else {

        return nil;

    }

}

@end

人类能够理解的信息类：

}

使用的话，给出NSDate，然后解析出来，就是这么简单:)
