年和日转化为天干地支

使用的代码：

_yearLabel.text = [time getYearHeavenlyStemsEarthlyBranches];

NSString+Extension.h文件

#import <Foundation/Foundation.h>@interface NSString (Extension)/** *  把绝对时间的具体一天转换为天干地址，非枚举法 */-(NSString *)getDayHeavenlyStemsEarthlyBranches;/** *  把绝对时间的具体年份转换为天干地址 */-(NSString *)getYearHeavenlyStemsEarthlyBranches;/** *  把绝对时间的日转换为十二生肖，枚举法 */-(NSString *)getZodiac;@end

月转化为天干地址和年转化为天干地支类似，我就不累述了。
