    <p>A synchronous <code>NSURLConnection</code> will absolutely work with <code>NSURLCredentialStorage</code>. Here's how things usually work:</p> <ol> <li><code>NSURLConnection</code> requests the page from the server</li> <li>The server replies with a 401 response</li> <li><code>NSURLConnection</code> looks to see what credentials it can glean from the URL</li> <li>If the URL did <strong>not</strong> provide full credentials (username and password), <code>NSURLConnection</code> will also consult <code>NSURLCredentialStorage</code> to fill in the gaps</li> <li>If full credentials have <em>still</em> not been determined, <code>NSURLConnection</code> will send the <code>-connection:didReceiveAuthenticationChallenge:</code> delegate method asking for credentials</li> <li>If the <code>NSURLConnection</code> now finally has full credentials, it retries the original request including authorization data.</li> </ol> <p>By using the synchronous connection method, you <strong>only</strong> lose out on step 5, the ability to provide custom authentication. So, you can either pre-provide authentication credentials in the URL, or place them in <code>NSURLCredentialStorage</code> before sending the request. e.g.</p> <pre><code>NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"http://user:pass@example.com"]]; [NSURLConnection sendSynchronousRequest:request returningResponse:NULL error:NULL]; </code></pre> <p>or:</p> <pre><code>NSURLCredential *credential = [NSURLCredential credentialWithUser:@"user" password:@"pass" persistence:NSURLCredentialPersistenceForSession]; NSURLProtectionSpace *protectionSpace = [[NSURLProtectionSpace alloc] initWithHost:@"example.com" port:0 protocol:@"http" realm:nil authenticationMethod:nil]; [[NSURLCredentialStorage sharedCredentialStorage] setDefaultCredential:credential forProtectionSpace:protectionSpace]; [protectionSpace release]; NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"http://example.com"]]; [NSURLConnection sendSynchronousRequest:request returningResponse:NULL error:NULL]; </code></pre>

    1. COI just came across this. I'm _very_ new to ObjectiveC but I was wondering if any objects (specifically credential and protectionSpace) had to be released. Btw I implemented this method on an asynchronous call (initWithRequest) and still got the didReceiveAuthenticationChallenge callback.

    2. CO@Bill, protectionSpace does need releasing if used in production code as I used +alloc.

    3. COprotectionSpace has to be released. alloc will return an object with retainCount == 1 so after [... setDefaultCredential:...] you should release it like [protectionSpace release];

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.
