title: NSURLConnection not responding
body: <p>I'm trying to get some data from an URL, but for some reason, nothing happens when I do the following. Neither <code>didReceiveResponse:</code>, <code>didReceiveData:</code>, <code>didFailWithError:</code> or <code>connectionDidFinishLoading:</code> are reached, except when I add a timeout to my request by doing this: <code>[request setTimeoutInterval:10.0]</code></p>
  
  <p>Here's what I'm doing :</p>
  
  <pre><code>-(void)getConfigFromServer{
      [self getContentAtURL:kUrlGetUser];
  }
  
  //Va chercher le contenu à l'URL passée en paramètre
  - (void)getContentAtURL: (NSURL *)url {
  
      [UIApplication sharedApplication].networkActivityIndicatorVisible = YES;
  
      NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults];
      NSString * userLogin = [userDefaults objectForKey:@"UserLogin"];
      NSString * userPassword = [userDefaults objectForKey:@"UserPassword"];
      NSURL * urlFinal = [NSURL URLWithString:[NSString stringWithFormat:@"%@", url]];
      NSLog(@"Request : %@", [NSString stringWithFormat:@"%@", url]);
      NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
      [request setURL:urlFinal];  
      [request setHTTPShouldHandleCookies:NO];
      [request setTimeoutInterval:10.0];
  
      NSString *sourceString = [NSString stringWithFormat:@"%@:%@", userLogin, userPassword]; 
      NSData * sourceData = [sourceString dataUsingEncoding:NSUTF8StringEncoding];  
      NSString *authString = [sourceData base64EncodedString];  
  
      authString = [NSString stringWithFormat: @"Basic %@", authString];
      [request setValue:authString forHTTPHeaderField:@"Authorization"];
      [request setValue:@"text/xml" forHTTPHeaderField:@"Accept"];
      NSURLConnection * connection=[NSURLConnection connectionWithRequest:request delegate:self];
  
      if(connection){
          NSLog(@"Connection started");
          receivedData = [NSMutableData data];
      }else{
          NSLog(@"Error while trying to initiate the connection");
      }
  }
  
  - (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response {
      [receivedData setLength:0];
      if ([response respondsToSelector:@selector(statusCode)])
      {
          int statusCode = [((NSHTTPURLResponse *)response) statusCode];
          if (statusCode &gt;= 400)
          {
              [connection cancel];  // stop connecting; no more delegate messages
              NSDictionary *errorInfo
                  = [NSDictionary dictionaryWithObject:[NSString stringWithFormat:
                  NSLocalizedString(@"Server returned status code %d",@""),
                  statusCode]
                      forKey:NSLocalizedDescriptionKey];
              NSError *statusError = [NSError errorWithDomain:@"Error"
                  code:statusCode
                  userInfo:errorInfo];
              [self connection:connection didFailWithError:statusError];
          }
      }
  }
  
  - (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data{
      [receivedData appendData:data];
  }
  
  - (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error{
      [UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
      NSLog(@"Connection failed! Error - %@ %@",[error localizedDescription],[[error userInfo] objectForKey:NSURLErrorFailingURLStringErrorKey]);
  }
  
  -(void)connectionDidFinishLoading:(NSURLConnection *)connection{
      [UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
      [self fetchedData:receivedData];
  }

  <p>EDIT : I'm still having this problem, and now have it on the actual device too. As I said it in the comments, I use ARC on this app for the first time, and I'm using XCode 4.2.</p>
  
  <p>Any idea?</p>
