前言 本人以前写过一个数据模型存储方法，是我在上上家公司做缓存框架的时候写的，具体也就是在FMDB的基础上封装，直接对数据模型进行存储操作，如下：

《iOS-基于FMDB的操作封装，模型对象的增删改查》

最近本人也不是很忙，加之在Python项目中用到Redis和在APP中用到NSUserDefaults，我就想做一个便捷的基于数据库的键值对存储方案，当然这个方案并不比Redis优秀，我们也知道Redis是直接从内存中读取，所以速度方面没法说，但是在APP中我们不能把键值对放在内存中吧，本来APP的内存就不宽裕！

ZFJRedisLib 功能结构 ZFJRedisLib主要包含ZFJRedis和ZFJTable两部分，ZFJRedis主要是用于键值对存储，使用简单方便；ZFJTable主要是对于数据模型进行增删改查操作！全部API如下： image ZFJRedis ZFJRedis将会自动在本地创建一个ZFJRedis的表，用于存储键值对数据；

1.存取值 字符串-NSString

// NSString
[ZFJRedis zfj_setValue:@"zhangfujie1128222====" forKey:@"name"];
// 取值
NSString *value = [ZFJRedis zfj_valueForKey:@"name"];
NSLog(@"%@",value);

数字对象-NSNumber

// NSNumber
[ZFJRedis zfj_setValue:@(20) forKey:@"age"];
// 取值
NSNumber *age = [ZFJRedis zfj_valueForKey:@"age"];
NSLog(@"%@",age);

数组-NSArray

// NSArray
[ZFJRedis zfj_setValue:@[@"111", @(222)] forKey:@"array1"];
// 取值
NSArray *array = [ZFJRedis zfj_valueForKey:@"array1"];
NSLog(@"%@",array);

字典-NSDictionary

// NSDictionary
NSDictionary *dict = @{@"name":@"zhangfujie", @"age":@(22), @"sex":@"man"};
[ZFJRedis zfj_setValue:dict forKey:@"zfj_infors"];
// 取值
NSDictionary *dict_value = [ZFJRedis zfj_valueForKey:@"zfj_infors"];
NSLog(@"%@",dict_value);

数据-NSData

// NSData
NSData *data = [NSJSONSerialization dataWithJSONObject:@[@"aaaaa", @"bbbbb"] options:NSJSONWritingPrettyPrinted error:nil];
[ZFJRedis zfj_setValue:data forKey:@"arrayData"];
// 取值
NSData *data_new = [ZFJRedis zfj_valueForKey:@"arrayData"];
NSLog(@"data_new == %@",data_new);

数据模型-model

// NSObject 数据模型
ZFJModel *model = [[ZFJModel alloc] init];
model.name = @"张福杰";
model.age = 22;
// 存
[ZFJRedis zfj_setValue:model forKey:@"model"];
// 取值
ZFJModel *model_my = [ZFJRedis zfj_valueForKey:@"model"];
NSLog(@"%@",model_my.name);
NSLog(@"%ld",model_my.age);

批量存数据

//根据字典赋值
NSMutableDictionary *value_dict = [[NSMutableDictionary alloc] init];
[value_dict setValue:@"aaaaaaaa" forKey:@"key_string"];
[value_dict setValue:@(111) forKey:@"key_number"];
[value_dict setValue:@[@"wwwwwww11111", @(222)] forKey:@"key_array"];
[value_dict setValue:@{@"name":@"zhangfujie", @"age":@(22)} forKey:@"key_dict"];
[value_dict setValue:model_my forKey:@"key_model"];
[ZFJRedis zfj_setValuesForKeysWithDictionary:value_dict];

批量取数据

NSDictionary *dict = [ZFJRedis zfj_dictionaryWithValuesForKeys:value_dict.allKeys];
NSLog(@"dict == %@",dict);

2.查询 获取全部keys

// 获取全部keys
NSArray *keys = [ZFJRedis zfj_allKeys];
NSLog(@"keys == %@",keys);

获取全部values

// 获取全部values
NSArray *values = [ZFJRedis zfj_allValues];
NSLog(@"values == %@",values);

获取全部条数

// 获取全部条数
NSInteger count = [ZFJRedis zfj_count];
NSLog(@"count == %ld",count);

判断key是否存在

// 判断当前key是否存在
BOOL isExist = [ZFJRedis zfj_isExistkey:@"name"];
if(isExist){
    NSLog(@"name 存在");
}else{
    NSLog(@"name 不存在");
}

3.删除 根据key删除

// 删除
[ZFJRedis zfj_removeObjectForKey:@"array"];

根据keys删除

// 根据keys删除数据
NSArray *key_list = @[@"name", @"age"];
[ZFJRedis zfj_removeObjectsForKeys:key_list];

删除全部

// 删除全部
[ZFJRedis zfj_removeAllObjects];

ZFJTable ZFJTable是根据数据模型自动创建表，直接根据模型进行增删改查操作的！

1.创建表 // 创建表 BOOL isScu = [ZFJTable zfj_createTable:[ZFJModel class]]; if(isScu){ NSLog(@"ZFJModel表创建成功"); }else{ NSLog(@"ZFJModel表创建失败"); } 2.删除表 //删除表 BOOL isScu = [ZFJTable zfj_removeTable:[ZFJModel class]]; if(isScu){ NSLog(@"ZFJModel表删除成功"); }else{ NSLog(@"ZFJModel表删除失败"); } 3.删除全部表 // 删除数据库 BOOL isScu = [ZFJTable zfj_removeAllTables]; if(isScu){ NSLog(@"数据库删除成功"); }else{ NSLog(@"数据库删除失败"); } 4.插入数据 // 插入一条数据 ZFJModel *model_0 = [[ZFJModel alloc] init]; model_0.name = @"张福杰"; model_0.age = 22; model_0.gender = @"男"; [ZFJTable zfj_insertModel:model_0 completed:^(NSError * _Nonnull error) { NSLog(@"error:%@",error); }];

// 插入多条数据
ZFJModel *model_0 = [[ZFJModel alloc] init];
model_0.name = @"张福杰";
model_0.age = 22;
model_0.gender = @"男";

ZFJModel *model_1 = [[ZFJModel alloc] init];
model_1.name = @"大白菜";
model_1.age = 88;
model_1.gender = @"女";
NSArray *models = @[model_0, model_1];
[ZFJTable zfj_insertModels:models completed:^(NSError * _Nonnull error) {
    NSLog(@"error:%@",error);
}];

5.删除数据 // 删除数据 BOOL isScu = [ZFJTable zfj_deleteModel:[ZFJModel class] where:@"name = '张福杰'"]; if(isScu){ NSLog(@"数据删除成功"); }else{ NSLog(@"数据删除失败"); } 6.修改数据 // 修改数据 ZFJModel *model_2 = [[ZFJModel alloc] init]; model_2.name = @"大白菜"; model_2.age = 22; model_2.gender = @"女"; [ZFJTable zfj_updateModel:model_2 byKey:@"name" completed:^(NSError * _Nonnull error) { NSLog(@"error:%@",error); }];

// 修改多条数据
ZFJModel *model_3 = [[ZFJModel alloc] init];
model_3.name = @"张福杰";
model_3.age = 222;
model_3.gender = @"男男";

ZFJModel *model_4 = [[ZFJModel alloc] init];
model_4.name = @"大白菜";
model_4.age = 222;
model_4.gender = @"女女";

NSArray *models = @[model_3, model_4];
[ZFJTable zfj_updateModels:models byKey:@"name" completed:^(NSError * _Nonnull error) {
    NSLog(@"error:%@",error);
}];

7.数据查询 // 查询全部数据 [ZFJTable zfj_selectTable:[ZFJModel class] completed:^(NSError * _Nonnull error, NSArray * _Nonnull models) { for (ZFJModel *model in models) { NSLog(@"%@",model.name); } }];

// 条件查询
[ZFJTable zfj_selectTable:[ZFJModel class] where:@"name = '张福杰'" completed:^(NSError * _Nonnull error, NSArray * _Nonnull models) {
    for (ZFJModel *model in models) {
        NSLog(@"%@",model.name);
    }
}];

// 查询数据条数
NSInteger count = [ZFJTable zfj_selectTableCount:[ZFJModel class]];
NSLog(@"count == %ld",count);

// 根据条件查询数量
NSDictionary *parameters = @{@"name":@"张福杰", @"age":@(22)};
NSString *sqlStr = @"name = '张福杰' and age = '22'";
NSInteger count = [ZFJTable zfj_selectTableCount:[ZFJModel class] where:sqlStr];
NSLog(@"count == %ld",count);

8.表扩展字段 // 向某个表添加一个字段 BOOL isScu = [ZFJTable zfj_addProperty:[ZFJModel class] propertyName:@"newPro_1"]; if(isScu){ NSLog(@"字段添加成功"); }else{ NSLog(@"字段添加失败"); } 8.错误信息 // 最后一条错误 NSError *error = [ZFJTable zfj_lastTableError]; NSLog(@"error == %@",error); 源码 DEMO地址：gitee.com/zfj1128/ZFJ… GitHub地址：github.com/zfjsyqk/ZFJ… 使用教程 pod ‘ZFJRedisLib’ pod install 导入头文件#import “ZFJRedisHeader.h” 结束语 欢迎各位大佬提供宝贵的建议和意见，也欢迎大家进群或加本人QQ一起交流学习！
