Hello,

I would like to ask you about NSURLConnection in objective-c for iPhone.

I have one app that needs to connect to one webservice to receive data (about YouTube videos), Then I have all the things that I need to connect (Similar to Hello_Soap sample code in the web).

But now, my problem is that I create a class (inherits from NSObject) named Connection and I have implemented the methods: didReceiveResponse, didReceiveData, didFailWithError and connectionDidFinishLoading. Also the method:

-(void)Connect:(NSString *) soapMessage{
    NSLog(soapMessage);

    NSURL *url = [NSURL URLWithString:@"http://....."];
    NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url];
    NSString *msgLength = [NSString stringWithFormat:@"%d", [soapMessage length]];


    [theRequest addValue: @"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
    [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");
    }
}

But when from my AppDelegate I create one Connection object:

Connection * connect = [[Connection alloc] Init:num]; //It's only one param to test.
[connect Connect:method.soapMessage];

And I call this method, when this finishes, it doesn't continue calling didReceiveResponse, didReceiveData, didFailWithError or connectionDidFinishLoading. I'm trying to do this but I can't for the moment.

The thing I would like to do is to be able to call this class "Connection" each time that I want to receive data (after that to be parsed and displayed in UITableViews).

Thank you.
