NSString *urlString= [NSString stringWithFormat:#"http://demo.xyz.com/proj/webservices/display_records/1/%#%#%#",myid,name,password];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:urlString]];
conn= [[NSURLConnection alloc]initWithRequest:request delegate:self];
if(conn)
{
webdata=[[NSMutableData data]retain];
}
Use defalut connection methods

You using soap message okey then akshar first you create a class of NSObject and then define a method in .h file with 3 parameter as given in below code:-
in .h file
#interface GetPartParser : NSObject <NSXMLParserDelegate>
{
NSXMLParser *xmlParser;
NSMutableArray *getPartArr;
NSMutableDictionary *item;
NSString *currentElement;
NSMutableString *part_urlStr, *partNameStr;
}
#property (nonatomic,retain) NSMutableArray *getPartArr;
-(void) fetchPartXMLData:(NSInteger)empid:(NSInteger)serid:(NSInteger)seaid:(NSInteger)episodeid;
and in .m file :-
-(void) fetchPartXMLData:(NSInteger)empid:(NSInteger)serid:(NSInteger)seaid :(NSInteger)episodeid
{
NSURL *myURL = [NSURL URLWithString:#"http://webservices.asmx"];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL: myURL cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];
NSString *soapMessage = [NSString stringWithFormat:#"<?xml version=\"1.0\" encoding=\"utf-8\"?>"
"<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/\">"
"<soap:Body>"
"<GetPart xmlns=\"http://tempuri.org/\">"
"<empid>%d</empid>"
"<serid>%d</serid>"
"<seaid>%d</seaid>"
"<episodeId>%d</episodeId>"
"</GetPart>"
"</soap:Body>"
"</soap:Envelope>",empid,serid,seaid,episodeid];
NSLog(#"soapMessage :%#",soapMessage);
[request addValue:#"text/xml; charset=utf-8" forHTTPHeaderField:#"Content-Type"];
[request addValue:#"http://tempuri.org/GetPart" forHTTPHeaderField:#"SOAPAction"];
NSString *msgLength = [NSString stringWithFormat:#"%d",[soapMessage length]];
[request addValue:msgLength forHTTPHeaderField:#"Content-Length"];
[request setHTTPMethod: #"POST"];
[request setHTTPBody:[soapMessage dataUsingEncoding:NSUTF8StringEncoding]];
NSURLResponse *returnedResponse = nil;
NSError *returnedError = nil;
NSData *barData = [NSURLConnection sendSynchronousRequest:request returningResponse:&returnedResponse error:&returnedError];
NSString *barString = [[NSString alloc] initWithBytes:[barData bytes] length:[barData length] encoding:NSUTF8StringEncoding];
NSLog(#"barString :%#",[[barString stringByReplacingOccurrencesOfString:#"<" withString:#"<"] stringByReplacingOccurrencesOfString:#">" withString:#">"]);
NSData* data=[[[barString stringByReplacingOccurrencesOfString:#"<" withString:#"<"] stringByReplacingOccurrencesOfString:#">" withString:#">"] dataUsingEncoding:NSUTF8StringEncoding];
xmlParser = [[NSXMLParser alloc] initWithData:data];
[xmlParser setDelegate:self];
[xmlParser setShouldResolveExternalEntities:NO];
[xmlParser setShouldProcessNamespaces:NO];
[xmlParser setShouldReportNamespacePrefixes:NO];
[xmlParser parse];
}
- (void)parserDidStartDocument:(NSXMLParser *)parser
{
getPartArr =[[NSMutableArray alloc] init];
}
- (void)parser:(NSXMLParser *)parser parseErrorOccurred:(NSError *)parseError
{
NSString * errorString = [NSString stringWithFormat:#"Unable to download story feed from web site (Error code %i )", [parseError code]];
UIAlertView * errorAlert = [[UIAlertView alloc] initWithTitle:#"Error loading content" message:errorString delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil];
[errorAlert show];
}
- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName attributes:(NSDictionary *)attributeDict
{
{
currentElement = [elementName copy];
if ([elementName isEqualToString:#"part"])
{
item = [[NSMutableDictionary alloc] init];
part_urlStr = [[NSMutableString alloc]init];
partNameStr = [[NSMutableString alloc]init];
}
}
}
- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
{
if ([currentElement isEqualToString:#"part_url"])
{
[part_urlStr appendString:string];
}
if ([currentElement isEqualToString:#"partName"])
{
[partNameStr appendString:string];
}
}
- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName
{
if ([elementName isEqualToString:#"part"])
{
[item setObject:part_urlStr forKey:#"part_url"];
[item setObject:partNameStr forKey:#"partName"];
[getPartArr addObject:[item copy]];
}
NSLog(#"item dictionary....%#",partNameStr);
}
- (void)parserDidEndDocument:(NSXMLParser *)parser
{
NSLog(#"getPartArr :%#",getPartArr);
}
it helps you and give what you want...
if you like then mark it as accepted

An event simpler way to get a ws result is:
NSString *urlString= [NSString stringWithFormat:#"http://demo.xyz.com/proj/webservices/display_records/1/%#%#%#",myid,name,password];
NSString *wsRes = [NSString stringWithContentsOfURL:urlStribng encoding: NSUTF8StringEncoding error:nil];
Consider extending this sample with error handling if you are going to use it.
