獲取農曆方法

聲明：以下爲使用IOS的 NSChineseCalendar 網上之前發現有人說這個方法不是完全準確，有些日期會顯示的不對，本人沒有驗證過，也實在懶得用C++那套方法去實現。

另外我做的不過是個簡單的功能，還不包括什麼節氣 節日那些複雜有高端的功能，如果哪位大神不吝賜教 小弟在此感激了。

方法總的說來就這樣： 

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

    NSArray *chineseYears = [NSArray arrayWithObjects:
                       @"甲子", @"乙丑", @"丙寅", @"丁卯",  @"戊辰",  @"己巳",  @"庚午",  @"辛未",  @"壬申",  @"癸酉",
                       @"甲戌",   @"乙亥",  @"丙子",  @"丁丑", @"戊寅",   @"己卯",  @"庚辰",  @"辛己",  @"壬午",  @"癸未",
                       @"甲申",   @"乙酉",  @"丙戌",  @"丁亥",  @"戊子",  @"己丑",  @"庚寅",  @"辛卯",  @"壬辰",  @"癸巳",
                       @"甲午",   @"乙未",  @"丙申",  @"丁酉",  @"戊戌",  @"己亥",  @"庚子",  @"辛丑",  @"壬寅",  @"癸丑",
                       @"甲辰",   @"乙巳",  @"丙午",  @"丁未",  @"戊申",  @"己酉",  @"庚戌",  @"辛亥",  @"壬子",  @"癸丑",
                       @"甲寅",   @"乙卯",  @"丙辰",  @"丁巳",  @"戊午",  @"己未",  @"庚申",  @"辛酉",  @"壬戌",  @"癸亥", nil];

    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", @"臘月", nil];


    NSArray *chineseDays=[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];


    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 *y_str = [chineseYears objectAtIndex:localeComp.year-1];
    NSString *m_str = [chineseMonths objectAtIndex:localeComp.month-1];
    NSString *d_str = [chineseDays objectAtIndex:localeComp.day-1];

    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單獨的函數來方便獲取，例如獲取月份：

+(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", @"臘月", 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獲取NSDate 那麼額外加個方法用來根據string和format來得到對應的 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;
}

使用方法類似這樣,比如獲取世界末日那一時刻的Date～～～

NSDate *date = [Tool_Functions getDateWithDateString:@"2012-12-21 15:14:35"
                                            formatString:@"yyyy-MM-dd HH:mm:ss"];
