一、YUDBModel 介紹
- 架構: 使用runtime和Sqlite實現(xiàn)NSObject擴展類YUDBModel,直接實現(xiàn)(json反序列化對象-對象增刪改查數(shù)據(jù)庫-對象序列化)
- 易用: 無需繼承，直接實現(xiàn)序列化、反序列化、一行代碼操作數(shù)據(jù)庫
- 穩(wěn)定: 耦合度低，容錯率高，兼容復雜和特殊數(shù)據(jù)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(shù)據(jù)(deserialize())，支持使用Sqlite函數(shù)進行查詢.
- 強大: 支持json反序列化對象-對象增刪改查數(shù)據(jù)庫-對象序列化，支持模型嵌套存儲和多表嵌套復雜查詢
- 智能: 自動增刪改表字段，自動初始化空對象(NSObject,NSArray,NSDictionary,NSString)
