    <p><strong>SITUATION</strong></p> <ul> <li>Using AFNetworking (NSURLConnection) to access my server API</li> <li>The API needs Basic Authentication with token as username</li> <li>The API returns HTTP 401 when token is invalid</li> <li>I set the Basic Authentication headers before any request</li> <li><p>If it returns 401, I retry like this:</p> <pre><code>AFHTTPRequestOperation *requestOperation = [MyHTTPClient.sharedClient HTTPRequestOperationWithRequest:request success:^(AFHTTPRequestOperation *operation, id responseObject) { processSuccessBlock(operation, responseObject); } failure:^(AFHTTPRequestOperation *operation, NSError *error) { processFailureBlock(operation, error); if (operation.response.statusCode == 401) [MyHTTPClient.sharedClient refreshTokenAndRetryOperation:operation success:processSuccessBlock failure:processFailureBlock]; }]; </code></pre></li> </ul> <p><strong>PROBLEM</strong></p> <ul> <li>When the server returns HTTP 401 with a Basic Authentication challenge, AFNetworking/NSURLConnection <strong>sends the identical request twice</strong> (initial request and then in answer to the authentication challenge)</li> <li>But because of the code above that I handle the HTTP 401 myself, <strong>this is totally unnecessary</strong> and I want it to stop answering the authentication challenge automatically</li> </ul> <p><strong>WHAT I'VE TRIED</strong></p> <ul> <li>Responding with <code>cancelAuthenticationChallenge:</code> to <code>willSendRequestForAuthenticationChallenge:</code> is aborting the second call, but it gives the error code -1012 (NSURLErrorUserCancelledAuthentication) instead of 401 and masks the real response</li> </ul> <p><strong>How do you disable the authentication challenge response mechanism so you get the servers response without calling it twice?</strong></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.
