Connecting from IOS to ASP.Net Webservce - asp.net

Question

I am writing an IPad App that needs to connect to a webservice that returns and integer like this:
<int xmlns="http://schemas.microsoft.com/2003/10/Serialization/">0</int>
My code looks like this
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:verficationURL]];
[request setHTTPMethod:#"GET"];
NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
}
-(void) connection: (NSURLConnection *)connection didReceiveData:(NSData *)data{
[self.responseData appendData:data];
}
-(void)connectionDidFinishLoading:(NSURLConnection *)connection {
NSString *result = [[NSString alloc] initWithData:self.responseData encoding:NSUTF8StringEncoding];
NSLog(#"array: %s", result);
}
The connection does finish loading, but I am unable to get the value 0 out of the result. What is the right way to do this. Thank You

I'm assuming you get the result, so will respond only regarding the parsing.
I'm usually using XMLReader for easy xml parsing. There are also other third-party libraries that you can use, or use NSXMLParsing directly, however, you'll need to write a little more code for that.
Using it, the code for parsing would look like this:
NSError *error = nil;
NSDictionary *dict = [XMLReader dictionaryForXMLData:self.responseData error:&error];
NSNumber *result = [dict valueForKey:#"int"];
if(error||!result){
// handle error (either the result is not xml format, or the xml doesn't contain a 'int' key)
}
else {
// handle result
}
I haven't tested this exact code, but it should be mostly correct.

Please create REST based Web Services as it becomes very easy to interact with the DB and move on to JSON.
