IOS 将公历日期转换为中国农历

代码方法：

//日期阳历转换为农历；
- (NSString *)convertDateToNongLi:(NSString *)aStrDate
{
    NSDate *dateTemp = nil;
    NSDateFormatter *dateFormater = [[NSDateFormatter alloc]init];
    [dateFormater setDateFormat:@"yyyy-MM-dd"];
    dateTemp = [dateFormater dateFromString:aStrDate];
    
    NSCalendar* calendar = [[NSCalendar alloc]initWithCalendarIdentifier:NSChineseCalendar];
    NSDateComponents* components = [calendar components:NSMonthCalendarUnit|NSDayCalendarUnit fromDate:dateTemp];
    NSString* nongliMonth = [UserInfo sharedUserInfo].chineseMonths[components.month-1];
    NSString* nongliDay = [UserInfo sharedUserInfo].chineseDays[components.day-1];
    NSString* nongliString = [NSString stringWithFormat:@"%@%@",nongliMonth,nongliDay];

    return nongliString;
}

　使用：

    NSString *strDate = @"2012-06-24";
    NSString *nongLi = [self convertDateToNongLi:strDate];
