NSURLConnection distinguish 2 different request

Question

In my app I need to download and post some data... First of all I need to download some data and then I need to do a post request. I Use async request to don't freeze the UI of my app... But when I call my method to post some data... I don't care about data returned from server. But the this method are called also when I do some post request.

- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)aResponse
{
    NSLog(@"------------------------------- connectionDidReceiveResponse");
    expectedResponseLength = [NSNumber numberWithFloat:[aResponse expectedContentLength]];
    URLresponse = aResponse;
}

- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{   



    [self.responseData appendData:data];
}

How can I do my post request like this below without calling (automatic) this 2 methods (up) (used when I download info) and without freezing user GUI (I don't care data when I do post request but I need data in the 1st case)?

My post request is this:

- (void)postRequestWithURLState:(NSString *)url
{
    NSString *bodyRequest = nil;
    NSURL *requestURL = [NSURL URLWithString:url];
    NSMutableURLRequest *theRequest = [[NSMutableURLRequest alloc] init];

    //NSLog(@"-------------- bodyRequest: %@", bodyRequest);



    [theRequest setURL:requestURL];
    [theRequest setTimeoutInterval:2.0];
    [theRequest setHTTPMethod:@"POST"];
    [theRequest setHTTPBody:[bodyRequest dataUsingEncoding:NSASCIIStringEncoding]];
    [self.oauthAuthentication authorizeRequest:theRequest];
    NSURLConnection *conn = [NSURLConnection connectionWithRequest:theRequest delegate:self];




    self.web = conn;




}

I am not sure I get exactly what your concern is but two things. First, you could call postRequestWithURLState after the download connection has called - (void)connectionDidFinishLoading:(NSURLConnection *)theConnection. That way you make sure you have the downloaded data before you do the post. Second, the delegate methods get an NSURLConnection parameter so you can check in each method whether this is the download or the post operation. — onnoweb, Dec 06 '11 at 15:15
is there some way to do post request async without data back? Or how can I separate the 2 request maybe in other class... — Usi Usi, Dec 06 '11 at 15:23

I was looking around the internet for a solution, I eventually just created my own subclass of NSURLConnection and assigned a tag variable to distinguish. Check out this blog post for more information

You can hold a reference to each of the different requests after performing them, then make some conditional code in the delegate methods that does something different for the two.

That's a rudimentary solution and feels like treating symptoms to me. Maybe you should refactor your approach and create controllers for each of the two operations and perform all of network communication there (it seems like you're doing it all in a view controller now) rather than where you're doing it now.
