ios XML,JSON,配列を解析しNSMutableArray(List)に変換する<br>)

9850 ワード

一、紹介
JSON解析:
JSON([{...}{...}...])エンティティインスタンスの内容を含む複数のセクション({...})に分解し、エンティティのすべての属性値をRuntime()を使用してインスタンス({...}-->エンティティのインスタンス).すべてのセクション({...})を巡回します.XMLをNSMutableArray(List)に変換します.
XML解析:
XMLは、GDataXml(または正規)によって複数のエンティティインスタンスの内容を含む小さなセクションXMLに分解され、小さなセクションでRuntime(実行時)()によってエンティティのすべての属性値が見つかり、インスタンスに値が割り当てられ(正規検索実装)、あるセクションを巡ってXMLがNSMutableArray(List)に変換される.
配列解析:
XMLをつなぎ合わせ、GDataXmlでXMLをNSMutableArray(List)に変換します(プロセス全体を正規化することもできます).
3つの解析方法を共通クラス(GlobalApplication)に記述しました
実装方法に2つのヘッダファイルを追加することに注意してください.

#import <objc/runtime.h>
#import "GDataXMLNode.h"

使用方法:

    // User        
    // xml --> NSMutableArray (List<class>)
    NSMutableArray *retVal = [GlobalApplication jsonToArray:xml class:User.class];
    // xml --> NSMutableArray (List<class>)
    NSMutableArray *retVal = [GlobalApplication xmlToArray:xml class:User.class rowRootName:@"row"];
    // xml --> NSMutableArray (List<String>)
    NSMutableArray *retVal = [GlobalApplication xmlToArray:xml];
