我是电话编程的新手。我从 web 服务中得到了一些响应。但它没有在 nsxmlparser 中加载该数据。
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"

"<ToDate>2013-05-03</ToDate></OnlineStatus>\n"
"</soap:Body>\n"
"</soap:Envelope>"];
NSLog(@"%@",soapMessage);
NSURL *url = [NSURL URLWithString:@"http://www.ebidmanagerdemo.com/gjHouseOnline/xml/XMLDataService.asmx"];
NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url];
NSString *msgLength = [NSString stringWithFormat:@"%d", [soapMessage length]];
[theRequest addValue: @"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
[theRequest addValue: @"http://tempuri.org/OnlineStatus" forHTTPHeaderField:@"Soapaction"];
[theRequest addValue: msgLength forHTTPHeaderField:@"Content-Length"];
[theRequest setHTTPMethod:@"POST"];
[theRequest setHTTPBody: [soapMessage dataUsingEncoding:NSUTF8StringEncoding]];
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.
}
}
-(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{
[webData setLength: 0];
}
-(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
[webData appendData:data];
}
-(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
{
NSLog(@"ERROR with theConnenction");
}
-(void)connectionDidFinishLoading:(NSURLConnection *)connection
{
NSLog(@"DONE. Received Bytes: %d", [webData length]);
NSString *theXML = [[NSString alloc] initWithBytes: [webData mutableBytes] length:[webData length] encoding:NSUTF8StringEncoding];
theXML = [theXML stringByReplacingOccurrencesOfString:@"<" withString:@"<"];
theXML = [theXML stringByReplacingOccurrencesOfString:@">" withString:@">"];
theXML = [theXML stringByReplacingOccurrencesOfString:@"&" withString:@"&"];
NSLog(@" getting in xml %@",theXML);
NSLog(@"XMl is workinggggggggg");
xmlParser = [[NSXMLParser alloc]initWithData:webData];
NSXMLParser *aslamxml =[[NSXMLParser alloc]initWithData:dataa];
[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
{
if( xmlResults )
{
[self.soapResults appendString: string];
NSLog(@"soap result %@",soapResults);
}
}
-(void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName
{
if( [elementName isEqualToString:@"MachineIP"])
{
xmlResults = FALSE;
[arr_code addObject:soapResults];
// NSLog(@"hello %@",arr_code);
soapResults = nil;
}
else {
if( [elementName isEqualToString:@"MachineIP"])
{
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(@" getting in xml %@",theXML); 在控制台中它的显示下面认为

但是如果给 NSLog(@" iiiiii %@",xmlParser); 它是针对 XMLParser 的，它没有加载到 NSXMlparser 中，它显示为空，请任何人告诉我这段代码有什么错误？我不明白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>
我收到一些错误代码，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，我在下面的代码中得到了两次
<?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？
