SOAP Web Services in iPhone/iPad

Here i posted the code. simply follow the steps.....

Create one button in xib and implemented with name -(IBAction) read_data,
bcz when we press the button then it fired soap webservice.

firstView.h file

@interface firstView : UIViewController {

NSMutableArray *list;

UILabel *soapValue;

}

- (IBAction) read_data;

@end

firstView.m file

@implementation firstView

- (IBAction) read_data

{

 NSString *name=@"50";     // Here name is, we providing value. so u change to ur provide value.

NSString *soapMessage = [NSString stringWithFormat:

@"\n"

"\n"

"\n"

"n"

"%@n"

"n"

"\n"

"\n",name

];

NSLog(@"soap Message= %@",soapMessage);

NSURL *url = [NSURL URLWithString:@"http://w3schools.com/webservices/tempconvert.asmx"];    //Here is the your server URL

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/CelsiusToFahrenheit" 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] retain];

}

else

{

NSLog(@"theConnection is NULL");

}

}

-(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 theConenction");

[connection release];

[webData release];

}

-(void)connectionDidFinishLoading:(NSURLConnection *)connection

{

NSLog(@"DONE. Received Bytes: %d", [webData length]);

NSString *theXML = [[NSString alloc] initWithBytes: [webData mutableBytes] length:[webData length] encoding:NSUTF8StringEncoding];

NSLog(@"theXML %@",theXML);     //theXML is the ur server XML

[theXML release];

NSXMLParser *parser = [[NSXMLParser alloc] initWithData:webData];

[parser setDelegate:self];

[parser setDelegate:self];

[parser setShouldProcessNamespaces:NO];

[parser setShouldReportNamespacePrefixes:NO];

[parser setShouldResolveExternalEntities:NO];

[parser parse];

[parser release];

}

-(void) parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName

{

if([elementName isEqualToString:@"CelsiusToFahrenheitResult"])

{

list = [[NSMutableArray alloc] init];

}

}

-(void) parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName

{

if([elementName isEqualToString:@"CelsiusToFahrenheitResult"])

{

list = [[NSMutableArray alloc] init];

}

}

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

{

if(string)

{

NSLog(@"String Value= %@",string);    //this string value is the response value splitted from xml

}

}

Thanks
