YUDBModel【綠色插件】-對象序列化、反序列化、對象一鍵增刪改查
1、YUDBModel 介紹
- 架構: 使用runtime和Sqlite實現NSObject擴展類YUDBModel,直接實現(json反序列化對象-對象增刪改查數據庫-對象序列化)
- 易用: 無需繼承，直接實現序列化、反序列化、一行代碼操做數據庫
- 穩定: 耦合度低，容錯率高，兼容複雜和特殊數據類型
- 支持: (NSObject,NSArray,NSDictionary,NSData,NSString,NSNumber,NSURL,Int,double,long,float,Bool,char)類型
- 靈活: 支持反序列化json key替換，支持自設定主鍵，支持忽略模型存儲字段，支持反序列化代理之定義數據(deserialize())，支持使用Sqlite函數進行查詢.
- 強大: 支持json反序列化對象-對象增刪改查數據庫-對象序列化，支持模型嵌套存儲和多表嵌套複雜查詢
- 智能: 自動增刪改表字段，自動初始化空對象(NSObject,NSArray,NSDictionary,NSString)
2、YUDBModel 集成
-
手動複製《YUDBModel.framework》到工程git
-
使用Cocoapods管理github
3、YUDBModel 使用
YUDBModel配置
///設置數據庫路徑 extern void YUDBModel_SetupDBPath(NSString *path); ///設置對象歸檔路徑 extern void YUDBModel_SetupObjectPath(NSString *path); ///設置數據庫版本號 extern void YUDBModel_SetupDBVersion(NSString *version); ///打開日誌輸出 extern void YUDBModel_SetDBLog(BOOL on); ///刪除數據庫文件 extern BOOL YUDBModel_ClearDBFile();
