    <p>I'm struggling sending POST data to a server and receiving the correct response. I started by using setHTTPBody but moved to setHTTPBodyStream when I wasn't getting the correct server response for certain POST data and I read setHTTPBody has a memory leak on earlier iOS versions. The problem is setHTTPBodyStream causes the error - "Operation couldn't be completed. Connection reset by peer".</p> <p>Here's the code:</p> <pre><code>NSMutableURLRequest * request=[NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"secret but correct url goes here"] cachePolicy:NSURLRequestReloadIgnoringLocalAndRemoteCacheData timeoutInterval:10.0]; [request setHTTPMethod: @"POST"]; [request setHTTPBodyStream: [NSInputStream inputStreamWithData: [[NSString stringWithFormat:@"username=%@&amp;password=%@&amp;score=%i",[(NSString*)CFURLCreateStringByAddingPercentEscapes(kCFAllocatorDefault, (CFStringRef)ogl_view-&gt;username, NULL, CFSTR("?=&amp;+"), kCFStringEncodingUTF8) autorelease],[(NSString*)CFURLCreateStringByAddingPercentEscapes(kCFAllocatorDefault, (CFStringRef)text_field.text, NULL, CFSTR("?=&amp;+"), kCFStringEncodingUTF8) autorelease],ogl_view-&gt;score[0]] dataUsingEncoding:NSUnicodeStringEncoding]]]; NSURLConnection * connection = [[NSURLConnection alloc] initWithRequest: request delegate:self]; if (connection){ received_data = [[NSMutableData data] retain]; ogl_view-&gt;section = CURLING_PROCESS_CREDENTIALS; }else{ ogl_view-&gt;section = CURLING_LOGIN_OR_REGISTER; UIAlertView *connection_alert = [[UIAlertView alloc] initWithTitle:@"Error" message: @"Can't connect to server" delegate:self cancelButtonTitle:@"Close" otherButtonTitles: nil]; [connection_alert show]; [connection_alert release]; } </code></pre> <p>I can verify the server is fine and it works when I try a web-browser.</p> <p>Can somebody get me on the right track to sending data with HTTP and the POST method correctly?</p> <p>Thank you for any help.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
