YUDBModel【绿色插件】-对象序列化、反序列化、对象一键增删改查

1、YUDBModel 介绍

• 架构: 使用runtime和Sqlite实现NSObject扩展类YUDBModel,直接实现(json反序列化对象-对象增删改查数据库-对象序列化)
• 易用: 无需继承，直接实现序列化、反序列化、一行代码操做数据库
• 稳定: 耦合度低，容错率高，兼容复杂和特殊数据类型
• 支持: (NSObject,NSArray,NSDictionary,NSData,NSString,NSNumber,NSURL,Int,double,long,float,Bool,char)类型
• 灵活: 支持反序列化json key替换，支持自设定主键，支持忽略模型存储字段，支持反序列化代理之定义数据(deserialize())，支持使用Sqlite函数进行查询.
• 强大: 支持json反序列化对象-对象增删改查数据库-对象序列化，支持模型嵌套存储和多表嵌套复杂查询
• 智能: 自动增删改表字段，自动初始化空对象(NSObject,NSArray,NSDictionary,NSString)

2、YUDBModel 集成

• 手动复制《YUDBModel.framework》到工程

• 使用Cocoapods管理

3、YUDBModel 使用

YUDBModel配置

///设置数据库路径
extern void YUDBModel_SetupDBPath(NSString *path);

///设置对象归档路径
extern void YUDBModel_SetupObjectPath(NSString *path);

///设置数据库版本号
extern void YUDBModel_SetupDBVersion(NSString *version);

///打开日志输出
extern void YUDBModel_SetDBLog(BOOL on);

///删除数据库文件
extern BOOL YUDBModel_ClearDBFile();

数据存储 增、删、改、查

• 增 改

///直接插入一条数据
[NSObject insert:dbObj];
	
///直接插入多条数据
[NSObject insertObjs:@[dbObj]];

///保存一条数据（根据rowid查找 if数据存在更新else插入）
[NSObject save:dbObj];

///保存多条数据（根据rowid查找 if数据存在更新else插入）
[NSObject saveObjs:@[dbObj]];

///保存一条数据（根据key值条件查找 if数据存在更新else插入）
[NSObject save:dbObj withKey:@"name"];

///保存一条数据（根据多个key值条件查找 if数据存在更新else插入）
[NSObject save:dbObj withKeys:@[@"name"]];

///更新一条数据（只执行更新语句）
[NSObject update:dbObj where:@"name = 'BruceYu'"];

• 删

///删除表dbObj [obj Class]
[NSObject delete:[dbObj class]];

///根据条件key删除表[object class]数据
[NSObject delete:dbObj WithKey:@"name"];

///根据多个条件key删除表[object class]数据
[NSObject delete:dbObj withKeys:@[@"name"]];

///根据条件删除表[obj Class]数据
[NSObject delete:dbObj where:@"name = 'BruceYu' "];

• 查

///举个栗子
DBObj *obj = [DBObj queryWithkey:@"name" value:@"BruceYu"];

if (nil == obj) {
	obj = [[DBObj query:[DBObj class]where:@"info.infoLevel1.infoLevel2.infoLevel3.infoLevel4.name4 = 'level4'"] firstObject];
}

if (nil == obj) {
    obj = [[DBObj query:[DBObj class]] firstObject];
}

obj.integer = 100;
obj.name = @"hello";
[obj update];
