iOS-系统自带xml解析（自定义封装）

说实话，神他么用过xml解析，只是调了几次这种接口，每次都要写，好麻烦，自己封装一下，以后会有用吧。

首先是基类

#import <Foundation/Foundation.h>

@interface XmlParsemanager : NSObject<NSXMLParserDelegate>

+(instancetype) shareInstance;

+(id) allocWithZone:(struct _NSZone *)zone;

@property (nonatomic,strong) NSMutableDictionary *resultDic;

@property (nonatomic,strong) NSString *currentElementRet;

@property (nonatomic,strong) NSString *currentElementVal;

@property (nonatomic,strong) AFHTTPRequestOperationManager *manager;

- (void)initset;

//请求数据的自定义

- (NSDictionary *)firstApplyWith:(NSDictionary *)parameters andUrl:(NSString *)url;

@end

#import "XmlParsemanager.h"

@implementation XmlParsemanager

static XmlParsemanager* _instance =nil;

+(instancetype) shareInstance

{

static dispatch_once_t onceToken ;

dispatch_once(&onceToken, ^{

_instance = [[super allocWithZone:NULL] init] ;

[_instance initset];

}) ;

return _instance ;

}

+(id) allocWithZone:(struct _NSZone *)zone

{

return [XmlParsemanager shareInstance] ;

}

- (void)initset{

self.manager = [AFHTTPRequestOperationManager manager];

AFXMLParserResponseSerializer * responseSer = [AFXMLParserResponseSerializer new];

self.manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"text/html",nil];

[self.manager setResponseSerializer:responseSer];

}

- (NSDictionary *)firstApplyWith:(NSDictionary *)parameters andUrl:(NSString *)url{

[self.manager GET:url parameters:parameters success:^(AFHTTPRequestOperation *operation,id responseObject){

NSXMLParser * parser = (NSXMLParser *)responseObject;

parser.delegate = self;

[parser setShouldProcessNamespaces:YES];

//此法可行，但是处理麻烦

[parser parse];

if ([self.resultDic[@"Ret"] isEqualToString:@"0"] ) {

NSLog(@"登录成功!");

}else{

if ([self.resultDic[@"Ret"] isEqualToString:@"1"]) {

NSLog(@"登录失败!");

}elseif ([self.resultDic[@"Ret"] isEqualToString:@"2"]){

NSLog(@"密码错误!");

}

NSLog(@"requestFlagshipStoreData xml:%@",parser);

} failure:^(AFHTTPRequestOperation *operation,NSError *error) {

NSLog(@"requestFlagshipStoreData Error:%@",error);

}];

return self.resultDic;

}

#pragma mark - NSXMLParserDelegate委托处理

//在文档开始的时候触发

-(void)parserDidStartDocument:(NSXMLParser *)parser{

NSLog(@"解析开始！");

}

//解析起始标记

- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict{

NSLog(@"解析到一个元素的开头---%@",elementName);

// 根据需求的标签获取相关的数据

if ([elementName isEqualToString:@"Ret"]) {

// 在这里需要赋值

[self.resultDic setValue:@"占位数据Ret" forKey:@"Ret"];

// 将当前的标签值传给声明的标签属性

self.currentElementRet = elementName;

}

if ([elementName isEqualToString:@"Val"]) {

[self.resultDic setValue:@"占位数据Val" forKey:@"Val"];

// 将当前的标签值传给声明的标签属性

self.currentElementVal = elementName;

}

//解析文本节点

- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string{

NSLog(@"值：%@",string);

// 从数组中取出相关的Student对象,每次取数组中最后的一个元素,保证值为最新的对象内容

if ([self.currentElementRet isEqualToString:@"Ret"]) {

// KVC

[self.resultDic setValue:string forKey:self.currentElementRet];

}

if ([self.currentElementVal isEqualToString:@"Val"]) {

// KVC

[self.resultDic setValue:string forKey:self.currentElementVal];

}

//解析结束标记

- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName{

NSLog(@"解析到一个元素的结尾---%@",elementName);

self.currentElementRet =nil;

self.currentElementVal =nil;

}

//文档结束时触发

-(void) parserDidEndDocument:(NSXMLParser *)parser{

NSLog(@"解析结束！");

NSLog(@"Ret = %@",self.resultDic[@"Ret"]);

}

@end

只是一个运用系统自带解析的方法写的，蛮简单的额
