    <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]; } </code></pre> <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>

    2. COPlease tell, what is called when you set timeout? Request gets loaded or fails? If the latter, tell us error text. Default timeout is 60s, make sure you're patient enough to wait until failure methods are called.

    3. COYes, the server is online. Tried with many URL, to make sure it wasn't the problem. When setting the timeout, I'm getting this : `Connection failed! Error - The request timed out. ` followed by the URL.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
