title: Error message : [MC] Reading from public effective user settings & [MC] System group container for systemgroup.com.apple.configurationprofiles path is
body: <p>When I use the following code, I have error messages :</p>
  
  <pre><code>[NSURLConnection sendAsynchronousRequest:request queue:myQueue completionHandler:^(NSURLResponse *response, NSData *data, NSError *error) {
          NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse *) response;
          NSLog(@"response status code: %ld, error status : %@", (long)[httpResponse statusCode], error.description);
  
          if ((long)[httpResponse statusCode] &gt;= 200 &amp;&amp; (long)[httpResponse statusCode]&lt; 400)
              {
                 // do stuff
                  [self requestFunction]; //Web Service
              }
  }];
  </code></pre>

  </code></pre>
  
  <p>The [self requestFunction] function launch a simple request :</p>
  
  <pre><code>        NSMutableURLRequest* request = [[NSMutableURLRequest alloc] init];
          NSString *url_string = [bytes stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLQueryAllowedCharacterSet]];
          [request setURL:[NSURL URLWithString:[set_send_order stringByAppendingString: url_string]]];
          [request setCachePolicy:NSURLRequestReloadIgnoringLocalCacheData];
          [request setTimeoutInterval:timeOut];
          [NSURLConnection connectionWithRequest:request delegate:self]; 
  </code></pre>
  
  <p>I precise that the connectionDidFinishLoading: is not called, but if I launch it directly without the sendAsynchronousRequest:, it works. 
  So why the fact that I use sendAsynchronousRequest: function makes me appear the two error messages, and the miscalling of the connectionDidFinishLoading ? </p>
  
  <p>Thank you in advance.</p>
