1.工具类.h

#import 

NS_ASSUME_NONNULL_BEGIN

@interface QSUtilClass : NSObject

/**
 今天时间转换  格式 二零一九年七月二日

 @return 格式 二零一九年七月二日
 */
+ (NSString *)dateFormattertranceformWithToday;

/**
 时间转换 格式 二零一九年七月二日

 @param date NSDate
 @return 格式 二零一九年七月二日
 */
+ (NSString *)dateFormattertranceformWithDate:(NSDate *)date;

@end

NS_ASSUME_NONNULL_END

2.工具类.m

#import "QSUtilClass.h"

static NSDateFormatter * dateFormatter;

@implementation QSUtilClass

+ (NSString *)dateFormattertranceformWithToday {
    return [self.class dateFormattertranceformWithDate:[NSDate date]];
}

+ (NSString *)dateFormattertranceformWithDate:(NSDate *)date {
    if (!dateFormatter) {
        dateFormatter = [[NSDateFormatter alloc] init];
    }
    // 年
    [dateFormatter setDateFormat:@"YYYY"];
    NSString *yearStr = [dateFormatter stringFromDate:date];
    yearStr = [self.class yearTransform:yearStr];
    // 月
    [dateFormatter setDateFormat:@"M"];
    NSString *monStr = [dateFormatter stringFromDate:date];
    monStr = [self.class monthTransform:monStr];
    // 日
    [dateFormatter setDateFormat:@"d"];
    NSString *dateStr = [dateFormatter stringFromDate:date];
    dateStr = [self.class dayTransform:dateStr];
    NSString * resultString = [NSString stringWithFormat:@"%@年%@月%@日",yearStr,monStr,dateStr];
    NSLog(@"resultString:%@",resultString);
    return resultString;
}

+ (NSString *)yearTransform:(NSString *)year {
    
    NSArray *arabicNumeralsArray = @[@"0",@"1",@"2",@"3",@"4",@"5",@"6",@"7",@"8",@"9"];
    NSArray *chineseNumeralsArray = @[@"零",@"一",@"二",@"三",@"四",@"五",@"六",@"七",@"八",@"九"];
    NSDictionary *dictionary = [NSDictionary dictionaryWithObjects:chineseNumeralsArray forKeys:arabicNumeralsArray];
    NSString * resultString = [NSString stringWithFormat:@"%@%@%@%@",[dictionary objectForKey:[year substringWithRange:NSMakeRange(0, 1)]],[dictionary objectForKey:[year substringWithRange:NSMakeRange(1, 1)]],[dictionary objectForKey:[year substringWithRange:NSMakeRange(2, 1)]],[dictionary objectForKey:[year substringWithRange:NSMakeRange(3, 1)]]];
    return resultString;
}

+ (NSString *)monthTransform:(NSString *)month {
    NSString *arabicNumStr = month;
    NSArray *arabicNumeralsArray = @[@"1",@"2",@"3",@"4",@"5",@"6",@"7",@"8",@"9",@"10",@"11",@"12"];
    NSArray *chineseNumeralsArray = @[@"一",@"二",@"三",@"四",@"五",@"六",@"七",@"八",@"九",@"十",@"十一",@"十二"];
    NSDictionary *dictionary = [NSDictionary dictionaryWithObjects:chineseNumeralsArray forKeys:arabicNumeralsArray];
    NSString *chinese = [dictionary objectForKey:arabicNumStr];
    return chinese;
}

+ (NSString *)dayTransform:(NSString *)day {
    
    NSArray *arabicNumeralsArray = @[@"1",@"2",@"3",@"4",@"5",@"6",@"7",@"8",@"9"];
    NSArray *chineseNumeralsArray = @[@"一",@"二",@"三",@"四",@"五",@"六",@"七",@"八",@"九"];
    NSDictionary *dictionary = [NSDictionary dictionaryWithObjects:chineseNumeralsArray forKeys:arabicNumeralsArray];
    if (day.length == 1) {
        return [dictionary objectForKey:day];
    }
    
    NSString * firstCharacter  = [day substringToIndex:1];;
    NSString * secondCharacter = [day substringFromIndex:1];
    NSString * chineseFirst;
    if (firstCharacter.integerValue == 1) {
        chineseFirst = @"十";
    }
    else if (firstCharacter.integerValue == 2){
        chineseFirst = @"廿";
    }
    else {
        chineseFirst = @"三十";
    }
    NSString * chineseSecond   = [dictionary objectForKey:secondCharacter];
    NSString * resultString    = [NSString stringWithFormat:@"%@%@",chineseFirst,chineseSecond];
    
    return resultString;
}
