如何用IOS调用WebService（SOAP接口）

- (NSString *)skHkshListOfpagenow2:(NSInteger)aPagenow pagesize:(NSInteger)aPagesize {     MURPXzshServiceSoapBinding *binding = [[MURPXzshServiceSoapBinding alloc]initWithAddress:[NSString stringWithFormat:@"%@%@", self.jjjj, XZSH_SERVICE]];//接口地址  binding.logXMLInOut = YES;//可以直接copy  MURPXzshService_HkshList *parm = [[MURPXzshService_HkshList alloc] init];//接口中方法初始化  parm.xxxx = [umcid stringValue];//接口中方法传参数  parm.pagenow = [NSNumber numberWithInteger:aPagenow];//接口中方法传参数  parm.pagesize = [NSNumber numberWithInteger:aPagesize];//接口中方法传参数  MURPXzshServiceSoapBindingResponse *resp = [binding HkshListUsingParameters:parm];//调用方法     //下面是返回值  for (id mine in resp.bodyParts) {       if ([mine isKindOfClass:[MURPXzshService_HkshListResponse class]]) {             NSString *resultStr = [mine HkshListResult];             return resultStr;    }  }  return nil;}

- (void)viewDidAppear:(BOOL)animated {     [super viewDidAppear:animated];     //假如在这开始请求  NSString *webServiceBodyStr = [NSString stringWithFormat:                  @"<Jsjy_yjy xmlns=/"http://murpcn.com/murpwebservice//">"                  "<xxx>34192</xxx>"                  "<pagenow>1</pagenow>"                  "<pagesize>20</pagesize>"                  "</Jsjy_yjy>"];//这里是参数  NSString *webServiceStr = [NSString stringWithFormat:                @"<?xml version=/"1.0/" encoding=/"utf-8/"?>/n"                "<soap:Envelope xmlns:xsi=/"http://www.w3.org/2001/XMLSchema-instance/" xmlns:xsd=/"http://www.w3.org/2001/XMLSchema/" xmlns:soap=/"http://schemas.xmlsoap.org/soap/envelope//">/n"                "<soap:Body>/n"                "%@/n"                "</soap:Body>/n"                "</soap:Envelope>",                webServiceBodyStr];//webService头     NSString *SOAPActionStr = [NSString stringWithFormat:@"http://xxx.com/murpwebservice/%@", @"Jsjy_yjy"];//SOAPAction     NSURL *url = [NSURL URLWithString:@"http://xxxx/key/MurpjsjyService.asmx"];  NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url];  NSString *msgLength = [NSString stringWithFormat:@"%ld", webServiceStr.length];  [theRequest addValue:@"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-type"];  [theRequest addValue:SOAPActionStr forHTTPHeaderField:@"SOAPAction"];  [theRequest addValue:msgLength forHTTPHeaderField:@"Content-Length"];  [theRequest setHTTPMethod:@"POST"];  [theRequest setHTTPBody:[webServiceStr dataUsingEncoding:NSUTF8StringEncoding]];  NSURLConnection *theConn = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self];  if (theConn) {         NSLog(@"8888哈哈哈笑");  }else {    NSLog(@"5555你给我哭");  }} //接收到数据的代理- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response {      } - (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {     NSString *str = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];  NSLog(@"%@", str);//得到想要的XML字符串然后解析     //系统自带的  NSXMLParser *par = [[NSXMLParser alloc] initWithData:[str dataUsingEncoding:NSUTF8StringEncoding]];  [par setDelegate:self];//设置NSXMLParser对象的解析方法代理  [par parse];//调用代理解析NSXMLParser对象，看解析是否成功}//解析XML#pragma mark xmlparser//step 1 :准备解析- (void)parserDidStartDocument:(NSXMLParser *)parser{      }//step 2：准备解析节点- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict{  NSLog(@"%@", NSStringFromSelector(_cmd) );}//step 3:获取首尾节点间内容- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string{  NSLog(@"%@", string);} //step 4 ：解析完当前节点- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName{  NSLog(@"%@",NSStringFromSelector(_cmd) );} //step 5；解析结束- (void)parserDidEndDocument:(NSXMLParser *)parser{   }//获取cdata块数据- (void)parser:(NSXMLParser *)parser foundCDATA:(NSData *)CDATABlock{   }
