  381. 假设须要也能够拆成单独的函数来方便获取。比如获取月份：
  382.  
  383. +(NSString*)getChineseMonthWithDate:(NSDate *)date{  
  384.  
  385.     NSArray *chineseMonths=[NSArray arrayWithObjects:
  386.                             @"正月", @"二月", @"三月", @"四月", @"五月", @"六月", @"七月", @"八月",
  387.                             @"九月", @"十月", @"冬月", @"腊月", nil];  
  388.  
  389.     NSCalendar *localeCalendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSChineseCalendar];  
  390.  
  391.     unsigned unitFlags = NSYearCalendarUnit | NSMonthCalendarUnit |  NSDayCalendarUnit;  
  392.  
  393.     NSDateComponents *localeComp = [localeCalendar components:unitFlags fromDate:date];  
  394.  
  395.     //NSLog(@"%d_%d_%d  %@",localeComp.year,localeComp.month,localeComp.day, localeComp.date);  
  396.  
  397.     NSString *m_str = [chineseMonths objectAtIndex:localeComp.month-1];  
  398.  
  399.     [localeCalendar release];  
  400.  
  401.     return m_str;  
  402.  
  403. }  
  404.  
  405. 另外假设不知道怎样获取NSDate 那么额外加个方法用来依据string和format来得到相应的 NSDate：
  406.  
  407. +(NSDate *)getDateWithDateString:(NSString *)strDate formatString:(NSString*)strFormat{  
  408.  
  409.     NSDateFormatter *formatter = [[[NSDateFormatter alloc] init] autorelease];   
  410.  
  411.     NSTimeZone *timeZone =  [NSTimeZone timeZoneWithAbbreviation:@"GMT"];   
  412.  
  413.     //NSTimeZone *localTime = [NSTimeZone localTimeZone];    
  414.  
  415.     [formatter setTimeZone:timeZone];
  416.     [formatter setDateFormat : strFormat];        
  417.  
  418.     NSDate *dateTime = [formatter dateFromString:strDate];  
  419.  
  420.     return dateTime;
  421. }  
  422.  
  423. 用法相似这样,比方获取世界末日那一时刻的Date～～～
  424. NSDate *date = [Tool_Functions getDateWithDateString:@"2012-12-21 15:14:35"
  425.                                             formatString:@"yyyy-MM-dd HH:mm:ss"]; 
  426.  
  427. //获取农历方法2
  428. - (NSString *)lunarForSolar:(NSDate *)solarDate{
