Hi,
I am trying to access a webservice (written in .NET) from my iPhone application.
This is my code:
-(IBAction)buttonClicked:(id)sender {
NSString *postString =[NSString stringWithFormat:question];
NSLog(postString);
NSURL *url = [NSURL URLWithString: address+@"/execute"];
NSMutableURLRequest *req = [NSMutableURLRequest requestWithURL:url];
NSString *msgLength = [NSString stringWithFormat:@"%d", [postString length]];
[req addValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
[req addValue:msgLength forHTTPHeaderField:@"Content-Length"];
[req setHTTPMethod:@"POST"];
[req setHTTPBody: [postString dataUsingEncoding:NSUTF8StringEncoding]];
[activityIndicator startAnimating];
conn = [[NSURLConnection alloc] initWithRequest:req delegate:self];
if (conn) {
webData = [[NSMutableData data] retain];
}
}
-(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 {
[webData release];
[connection release];
}
-(void) connectionDidFinishLoading:(NSURLConnection *) connection {
NSLog(@"DONE. Received Bytes: %d", [webData length]);
NSString *theXML = [[NSString alloc]
initWithBytes: [webData mutableBytes]
length:[webData length]
encoding:NSUTF8StringEncoding];
//---shows the XML---
NSLog(theXML);
[theXML release];
[activityIndicator stopAnimating];
if (xmlParser)
{
[xmlParser release];
}
xmlParser = [[NSXMLParser alloc] initWithData: webData];
[xmlParser setDelegate: self];
[xmlParser setShouldResolveExternalEntities:YES];
[xmlParser parse];
[connection release];
[webData release];
}
It's entering the didReceiveResponse and didReceiveData methods but the following text is retrieved instead of the data I want:
Runtime Error body {font-family:"Verdana";font-weight:normal;font-size: .7em;color:black;} p {font-family:"Verdana";font-weight:normal;color:black;margin-top: -5px} b {font-family:"Verdana";font-weight:bold;color:black;margin-top: -5px} H1 { font-family:"Verdana";font-weight:normal;font-size:18pt;color:red } H2 { font-family:"Verdana";font-weight:normal;font-size:14pt;color:maroon } pre {font-family:"Lucida Console";font-size: .9em} .marker {font-weight: bold; color: black;text-decoration: none;} .version {color: gray;} .error {margin-bottom: 10px;} .expandable { text-decoration:underline; font-weight:bold; color:navy; cursor:hand; }

<h2> <i>Runtime Error</i> </h2></span> <font face="Arial, Helvetica, Geneva, SunSans-Regular,sans-serif ">
<b> Description: </b>An application error occurred on theserver. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.
<b>Details:</b> To enable the details of this specific errormessage to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".
<table width=100 gcolor="#ffffcc"> <tr> <td> <code><pre><!-- Web.Config Configuration File -->
<configuration> <system.web> <customErrors mode="Off"/> </system.web> </configuration>
</td> </tr> </table> <br> <b>Notes:</b> The current error page you are seeing can bereplaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.
<table width=100 gcolor="#ffffcc"> <tr> <td> <code><pre><!-- Web.Config Configuration File -->

Can anyone please help me?
Thanks!
