【开发工具】YTKKeyValueStore 键值存储--存储自定义类型

1，使用 'MJExtension' 处理字典和模型。

注意：自定义类型中包含自定义类型，需要实现 `+ (NSDictionary *)mj_objectClassInArray` 方法

@class Person;
@interface Group : NSObject
@property (nonatomic, strong) NSString *groupName;
@property (nonatomic, strong) NSArray<Person *> *members;
@property (nonatomic, strong) NSArray<Person *> *teachers;
@end

@implementation Group
+ (NSDictionary *)mj_objectClassInArray{
    return @{
             @"members": @"Person",
             @"teachers": [Person class]
             };
}
@end

2，YTKKeyValueStore 可以对系统类型的数据进行存储，对于自定义类型，将自定义类型处理成Json数据再进行存储即可。

#import <Foundation/Foundation.h>
#import "YTKKeyValueStore.h"

@interface YTKKeyValueStore (CustomObject)

/******** 自定义类型相关 *********************************************************/
/** 存储自定义类型 */
- (void)putCustomObject:(id)object
                 withId:(NSString *)objectId
              intoTable:(NSString *)tableName;

/** 存储包含自定义类型的数组 */
- (void)putArrWithCustomClass:(Class)aclass
                       object:(id)object
                       withId:(NSString *)objectId
                    intoTable:(NSString *)tableName;

/** 获取自定义类型的对象方法 */
- (id)getCustomClass:(Class)aclass
          objectById:(NSString *)objectId
           fromTable:(NSString *)tableName;

@end

@interface AGKeyValueManage : NSObject

+ (void)storeWithDBName:(NSString *)dbName tableName:(NSString *)tableName handle:(void (^)(YTKKeyValueStore *store, NSString *tableName))handle;

@end

#import "AGKeyValueManage.h"
#import "MJExtension.h"

@implementation YTKKeyValueStore (CustomObject)

- (void)putCustomObject:(id)object withId:(NSString *)objectId intoTable:(NSString *)tableName{
    NSDictionary *dic = [object mj_keyValues];
    [self putObject:dic withId:objectId intoTable:tableName];
}

/**
    将包含自定义对象的数组转成包含
 */
- (void)putArrWithCustomClass:(Class)aclass object:(id)object withId:(NSString *)objectId intoTable:(NSString *)tableName{
    NSArray *dicArr = [aclass mj_keyValuesArrayWithObjectArray:object];
    [self putObject:dicArr withId:objectId intoTable:tableName];
}

- (id)getCustomClass:(Class)aclass objectById:(NSString *)objectId fromTable:(NSString *)tableName{
    id object = [self getObjectById:objectId fromTable:tableName];
    id result;
    if ([object isKindOfClass:[NSArray class]]) {
        result = [aclass mj_objectArrayWithKeyValuesArray:object];
    }
    else{
        result = [aclass mj_objectWithKeyValues:object];
    }
    return result;
}
@end

@implementation AGKeyValueManage

+ (void)storeWithDBName:(NSString *)dbName tableName:(NSString *)tableName handle:(void (^)(YTKKeyValueStore *store, NSString *tableName))handle{
    if (!handle) {
        return;
    }
    YTKKeyValueStore *store = [[YTKKeyValueStore alloc] initDBWithName:dbName];
    [store createTableWithName:tableName];
    handle(store, tableName);
}
@end
