    NSString *chineseCal_str =[NSString stringWithFormat: @"%@_%@_%@",y_str,m_str,d_str];  

    [localeCalendar release];  

    return chineseCal_str;
}  

如果需要也可以拆成单独的函数来方便获取，例如获取月份：

+(NSString*)getChineseMonthWithDate:(NSDate *)date{  

    NSArray *chineseMonths=[NSArray arrayWithObjects:
                            @"正月", @"二月", @"三月", @"四月", @"五月", @"六月", @"七月", @"八月",
                            @"九月", @"十月", @"冬月", @"腊月", nil];  

    NSCalendar *localeCalendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSChineseCalendar];  

    unsigned unitFlags = NSYearCalendarUnit | NSMonthCalendarUnit |  NSDayCalendarUnit;  

    NSDateComponents *localeComp = [localeCalendar components:unitFlags fromDate:date];  

    //NSLog(@"%d_%d_%d  %@",localeComp.year,localeComp.month,localeComp.day, localeComp.date);  

    NSString *m_str = [chineseMonths objectAtIndex:localeComp.month-1];  

    [localeCalendar release];  

    return m_str;  

}  

另外如果不知道如何获取NSDate 那么额外加个方法用来根据string和format来得到对应的 NSDate：

+(NSDate *)getDateWithDateString:(NSString *)strDate formatString:(NSString*)strFormat{  

    NSDateFormatter *formatter = [[[NSDateFormatter alloc] init] autorelease];   

    NSTimeZone *timeZone =  [NSTimeZone timeZoneWithAbbreviation:@"GMT"];   

    //NSTimeZone *localTime = [NSTimeZone localTimeZone];    

    [formatter setTimeZone:timeZone];
    [formatter setDateFormat : strFormat];        

    NSDate *dateTime = [formatter dateFromString:strDate];  

    return dateTime;
}  

使用方法类似这样,比如获取世界末日那一时刻的Date～～～
NSDate *date = [Tool_Functions getDateWithDateString:@"2012-12-21 15:14:35"
                                            formatString:@"yyyy-MM-dd HH:mm:ss"]; 

//获取农历方法2
- (NSString *)lunarForSolar:(NSDate *)solarDate{

    //农历日期名

    NSArray *cDayName = [NSArray  arrayWithObjects:@"*",@"初一",@"初二",@"初三",@"初四",@"初五",@"初六",@"初七",@"初八",@"初九",@"初十",

                         @"十一",@"十二",@"十三",@"十四",@"十五",@"十六",@"十七",@"十八",@"十九",@"二十",

                         @"廿一",@"廿二",@"廿三",@"廿四",@"廿五",@"廿六",@"廿七",@"廿八",@"廿九",@"三十",nil];

    //农历月份名

    NSArray *cMonName = [NSArray arrayWithObjects:@"*",@"正",@"二",@"三",@"四",@"五",@"六",@"七",@"八",@"九",@"十",@"十一",@"腊",nil];

    //公历每月前面的天数

    const int wMonthAdd[12] = {0,31,59,90,120,151,181,212,243,273,304,334};

    //农历数据

    const int wNongliData[100] = {2635,333387,1701,1748,267701,694,2391,133423,1175,396438

获取时间日期的jQuery代码:         function getNewtime(){                 var newtime = new Date();                 var yy = newtime.getYear().toString();                 yy = '20' + yy.substring(yy.length -2) ;                 var mm =newtime.getMonth();     

一篇文章吃透iOS、JS的时间日期(Date, Calendar, Locale, TimeZone)

iOS 时间相关类 NSDate - 表示一个绝对的时间点. NSCalendar - 代表一个特定的日历,例如公历或者希伯来日历.它提供了一系列基于日期的计算,并且可以让你在"NSDate"和"NSDateComponents"对象之间进行转换. NSDateComponents - 允许你获取一个Date的特定内容,例如小时.分钟.年月日等等. NSTimeZone - 代表一个特定的时区信息,可以帮助跨时区的计算任务. 代码分析 废话少说,Show me th
