    Have a look at the NSURLRequest class in the API docs.

    In particular

    – HTTPBody
    – HTTPMethod

    For example:
    	NSMutableString *httpBodyString;
    	NSURL *url;
            NSMutableString *urlString;
    	
    	httpBodyString=[[NSMutableString alloc] initWithString:@"Name=The Big Bopper&Subject=Hello Baby&MsgBody=...You knooow what I like...Chantilly lace..."];
    	urlString=[[NSMutableString alloc] initWithString:@"http://www.somedomain.com/contactform.php"];
    
    	url=[[NSURL alloc] initWithString:urlString];
    	[urlString release];
    	
    	NSMutableURLRequest *urlRequest=[NSMutableURLRequest requestWithURL:url];
    	[url release];
    
    	[urlRequest setHTTPMethod:@"POST"];
    	[urlRequest setHTTPBody:[httpBodyString dataUsingEncoding:NSISOLatin1StringEncoding]];
    	[httpBodyString release];
    	
    	NSURLConnection *connectionResponse = [[NSURLConnection alloc] initWithRequest:urlRequest delegate:self];
    	
    	if (!connectionResponse)
    	{
    		NSLog(@"Failed to submit request");
    	}
    	else
    	{
    		NSLog(@"--------- Request submitted ---------");
    		NSLog(@"connection: %@ method: %@, encoded body: %@, body: %a", connectionResponse, [urlRequest HTTPMethod], [urlRequest HTTPBody], httpBodyString);
    		NSLog(@"New connection retain count: %d", [connectionResponse retainCount]);
    		responseData=[[NSMutableData data] retain];
    		NSLog(@"response", responseData);
    	}

    You could always do it as simple as stringWithContentsOfURL and pass a url with variables in it like
    http://test.com/index.php?test=1&test2=2
    

    Or do it in an xmlparser if you need to parse the results.. Either will do the job..

    If you don't want the data in plain text, you can just send the block w/ method post using the above.
