Question

I have a shopping cart in my app and an underlying data structure that I have serialized into an XML file. Im using the following code to place it on my server. However, nothing happens. Whe I check my server I donot find my file there. So I tried using just a string in place of the file and still the same. Nothing seems to be sent from the app to the server. Im running ths off the simulator.

Im wondering if there is anything wrong with this code.

CartSingleton *Cart = [CartSingleton getSingleton];

 id xmlFile = [Cart serializeCart];

 //Now send the xml file to the server

 NSURL *url = [[NSURL alloc] initWithString:@"http://www.XXXXXXXXX.com/iOS_Files/xmlFile"];

 NSMutableURLRequest *req = [[NSMutableURLRequest alloc] initWithURL:url];

 [req setHTTPMethod:@"POST"];

 NSData *paramData = [xmlFile dataUsingEncoding:NSUTF8StringEncoding];

 [req setHTTPBody:paramData];

 NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:req delegate:self];


 if(theConnection)

    {

      NSMutableData *data = [[NSMutableData alloc] init];

      self.receivedData = data;

      [data release];

    }

 else 

    {

      NSLog(@"Unable to make connection!");

    }

I would really appreciate any help.
Thanks

One possible problem with the above code (their may be others also), is that the connection setup will be asynchronous. This is why you had to supply a delegate object above. Therefore, the connection is not actually made until the delegate gets a callback to say it is ready.

Have you implemented any delegate methods?
