导入“ViewController.h”

Question

我是手机编程的新手。我从webservice获得了一些回复。但它没有在nsxmlparser中加载这些数据。

导入“ViewController.h”

@interface ViewController : UIViewController<UITableViewDelegate,UITableViewDataSource,NSXMLParserDelegate,NSURLConnectionDelegate>
{

    NSMutableData *webData;
    NSMutableString *soapResults;
    NSXMLParser *xmlParser;
    BOOL xmlResults;
    NSMutableArray *arr_code,*arr_name;
}
@property(nonatomic,retain)NSMutableArray *arr_code,*arr_name;
@property(nonatomic,retain)NSMutableData *webData;
@property(nonatomic,retain)NSMutableString *soapResults;
@property(nonatomic,retain)NSXMLParser *xmlParser;

导入“ViewController.h”

@synthesize arr_code,arr_name,webData,soapResults,xmlParser,nb,table;
- (void)viewDidLoad
{
    arr_code=[[NSMutableArray alloc]init];
    arr_name=[[NSMutableArray alloc]init];
    xmlResults =FALSE;
     NSString *soapMessage=[NSString stringWithFormat:
                           @"<?xml version=\"1.0\" encoding=\"utf-8\"?>\n"
                           "<soap:Envelope xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">\n"
                           "<soap:Body>\n"

    NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
      if(theConnection) {
        webData = [NSMutableData data];
    }
    else {
        NSLog(@"theConnection is NULL");

    NSString *msgLength = [NSString stringWithFormat:@"%d", [soapMessage length]];
    NSLog(@"%@",msgLength);
            [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    }
}

    NSLog(@"ERROR with theConnenction");
    }

-(void)connectionDidFinishLoading:(NSURLConnection *)connection

    [xmlParser setShouldResolveExternalEntities: YES];
    [xmlParser setDelegate: self];
    [xmlParser parse];
    NSLog(@" iiiiii %@",xmlParser);
}
-(void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *) namespaceURI qualifiedName:(NSString *)qName
   attributes: (NSDictionary *)attributeDict
{
    NSLog(@"fsdfsd");
    if( [elementName isEqualToString:@"MachineIP"])
    {
      if(!soapResults)
        {
            soapResults = [[NSMutableString alloc] init];

        }
        xmlResults = YES;

    }
    else
    {
        if( [elementName isEqualToString:@"MachineIP"])
        {


            if(!soapResults)
            {
                soapResults = [[NSMutableString alloc] init];

            }
            xmlResults = YES;

        }
    }
}

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

    }

    {
        xmlResults = FALSE;
        [arr_code addObject:soapResults];
       // NSLog(@"hello %@",arr_code);

        soapResults = nil;

    else {

        {
            xmlResults = FALSE;
            [arr_name addObject:soapResults];
            NSLog(@"hiii %@",arr_name);

            soapResults = nil;
        }
    }
    [table reloadData];

}

我得到这样的输出如果我给NSLog（@“get in xml％@”，theXML）; 在控制台中显示下面的想法

但是如果给予 NSLog（@“iiiiii％@”，xmlParser）;它是为XMLParser而不是在NSXMlparser中加载它显示为空可以任何正文告诉我这段代码中的错误是什么？我不知道为什么它没有加载到NSXMLparser中。

2013-05-27 19:13:35.738 NewC Newcafezee[1202:11303] XMl is workinggggggggg
2013-05-27 19:13:35.739 NewC Newcafezee[1202:11303]  iiiiii <NSXMLParser: 0x7191d20>

我收到的错误代码有些想法，如下所示

2013-05-27 19:43:35.962 NewC Newcafezee[1291:11303] error parsing XML: Unable to download story feed from web site (Error code 64 ) http://www.ebidmanagerdemo.com/gjHouseOnline/xml/XMLDataService.asmx

在上面的输出中，我得到两次代码

<?xml version="1.0" encoding="utf-8"?>

这是错误ra的主要原因？请告诉我什么是错误？

Answer 1

您已在soapResults数组中设置了值。尝试使用以下方法打印它： parserDidEndDocument。

- (void)parserDidEndDocument:(NSXMLParser *)parser

Answer 2

首先知道错误

-(void)parser:(NSXMLParser*)parser parseErrorOccurred:(NSError *)parseError
{
    NSLog(@"error:%@",parseError);

}

Answer 3

didEndElement的变化xmlResults = FALSE;到xmlResults = NO;

Web服务数据未在iphone中的NSXMLParser中加载

导入“ViewController.h”
