iOS-ZFJRedisLib-超便捷的鍵值對存儲方案，Sqlite數據模型存儲庫，APP緩存解決方案

前言

本人之前寫過一個數據模型存儲方法，是我在上上家公司作緩存框架的時候寫的，具體也就是在FMDB的基礎上封裝，直接對數據模型進行存儲操做，以下：

《iOS-基於FMDB的操做封裝，模型對象的增刪改查》

最近本人也不是很忙，加之在Python項目中用到Redis和在APP中用到NSUserDefaults，我就想作一個便捷的基於數據庫的鍵值對存儲方案，固然這個方案並不比Redis優秀，咱們也知道Redis是直接從內存中讀取，因此速度方面無法說，可是在APP中咱們不能把鍵值對放在內存中吧，原本APP的內存就不寬裕！

ZFJRedisLib

功能結構

ZFJRedisLib主要包含ZFJRedis和ZFJTable兩部分，ZFJRedis主要是用於鍵值對存儲，使用簡單方便；ZFJTable主要是對於數據模型進行增刪改查操做！所有API以下：

ZFJRedis

ZFJRedis將會自動在本地建立一個ZFJRedis的表，用於存儲鍵值對數據；

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);

數字對象-NSNumber

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

數組-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);

數據-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);

數據模型-model

// NSObject 數據模型
    ZFJModel *model = [[ZFJModel alloc] init];
    model.name = @"張福傑";
    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);

批量存數據

//根據字典賦值
    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];

批量取數據

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

2.查詢

獲取所有keys

// 獲取所有keys
    NSArray *keys = [ZFJRedis zfj_allKeys];
    NSLog(@"keys == %@",keys);

獲取所有values

// 獲取所有values
    NSArray *values = [ZFJRedis zfj_allValues];
    NSLog(@"values == %@",values);

獲取所有條數

// 獲取所有條數
    NSInteger count = [ZFJRedis zfj_count];
    NSLog(@"count == %ld",count);

判斷key是否存在

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

3.刪除

根據key刪除

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

根據keys刪除

// 根據keys刪除數據
    NSArray *key_list = @[@"name", @"age"];
    [ZFJRedis zfj_removeObjectsForKeys:key_list];

刪除所有

// 刪除所有
    [ZFJRedis zfj_removeAllObjects];

ZFJTable

ZFJTable是根據數據模型自動建立表，直接根據模型進行增刪改查操做的！

1.建立表

// 建立表
    BOOL isScu = [ZFJTable zfj_createTable:[ZFJModel class]];
    if(isScu){
        NSLog(@"ZFJModel表建立成功");
    }else{
        NSLog(@"ZFJModel表建立失敗");
    }

2.刪除表

//刪除表
    BOOL isScu = [ZFJTable zfj_removeTable:[ZFJModel class]];
    if(isScu){
        NSLog(@"ZFJModel表刪除成功");
    }else{
        NSLog(@"ZFJModel表刪除失敗");
    }

3.刪除所有表

// 刪除數據庫
    BOOL isScu = [ZFJTable zfj_removeAllTables];
    if(isScu){
        NSLog(@"數據庫刪除成功");
    }else{
        NSLog(@"數據庫刪除失敗");
    }

4.插入數據

// 插入一條數據
    ZFJModel *model_0 = [[ZFJModel alloc] init];
    model_0.name = @"張福傑";
    model_0.age = 22;
    model_0.gender = @"男";
    [ZFJTable zfj_insertModel:model_0 completed:^(NSError * _Nonnull error) {
        NSLog(@"error:%@",error);
    }];
    
    // 插入多條數據
    ZFJModel *model_0 = [[ZFJModel alloc] init];
    model_0.name = @"張福傑";
    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.刪除數據

// 刪除數據
    BOOL isScu = [ZFJTable zfj_deleteModel:[ZFJModel class] where:@"name = '張福傑'"];
    if(isScu){
        NSLog(@"數據刪除成功");
    }else{
        NSLog(@"數據刪除失敗");
    }

6.修改數據

// 修改數據
    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);
    }];
    
    // 修改多條數據
    ZFJModel *model_3 = [[ZFJModel alloc] init];
    model_3.name = @"張福傑";
    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.數據查詢

// 查詢所有數據
    [ZFJTable zfj_selectTable:[ZFJModel class] completed:^(NSError * _Nonnull error, NSArray * _Nonnull models) {
        for (ZFJModel *model in models) {
            NSLog(@"%@",model.name);
        }
    }];
    
    // 條件查詢
    [ZFJTable zfj_selectTable:[ZFJModel class] where:@"name = '張福傑'" completed:^(NSError * _Nonnull error, NSArray * _Nonnull models) {
        for (ZFJModel *model in models) {
            NSLog(@"%@",model.name);
        }
    }];
    
    // 查詢數據條數
    NSInteger count = [ZFJTable zfj_selectTableCount:[ZFJModel class]];
    NSLog(@"count == %ld",count);
    
    // 根據條件查詢數量
    NSDictionary *parameters = @{@"name":@"張福傑", @"age":@(22)};
    NSString *sqlStr = @"name = '張福傑' and age = '22'";
    NSInteger count = [ZFJTable zfj_selectTableCount:[ZFJModel class] where:sqlStr];
    NSLog(@"count == %ld",count);

8.表擴展字段

// 向某個表添加一個字段
    BOOL isScu = [ZFJTable zfj_addProperty:[ZFJModel class] propertyName:@"newPro_1"];
    if(isScu){
        NSLog(@"字段添加成功");
    }else{
        NSLog(@"字段添加失敗");
    }

8.錯誤信息

// 最後一條錯誤
    NSError *error = [ZFJTable zfj_lastTableError];
    NSLog(@"error == %@",error);
