    <p>I'm trying to use the delegate methods of NSURLConnection. The following methods are currently not being called:</p> <pre><code>- (void)connectionDidFinishLoading:(NSURLConnection *)connection; - (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data; - (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge; //I also want to be able to use self-signed https urls - (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace; //I also want to be able to use self-signed https urls </code></pre> <p>I'm currently using a synchronous call but asynchronous seems better because after I complete the code base I'm going to implement it into an iPhone application and I can't have my ui freezing.</p> <p>With the following method<code>responseData = [NSMutableData dataWithData:[NSURLConnection sendSynchronousRequest:request returningResponse:&amp;response error:&amp;error]];</code> </p> <p>I get back the data I need but using asynchronous I seems I have to use the delegate methods to get data back. I tried to add the delegate by using <code>@interface myClass : NSObject&lt;NSURLConnectionDelegate&gt;</code></p> <p>I'm calling my method as follows:</p> <pre><code>-(void)grabData{ NSArray* array = [NSArray arrayWithObjects:@"auth.login",@"user",@"pass", nil]; NSData* packed_array = [array messagePack]; NSURL* url = [NSURL URLWithString:@"https://192.168.1.115:3790/"]; NSMutableURLRequest* request = [[[NSMutableURLRequest alloc]initWithURL:url]retain]; [request setHTTPMethod:@"POST"]; [request setValue:@"RPC Server" forHTTPHeaderField:@"Host"]; [request setValue:@"binary/message-pack" forHTTPHeaderField:@"Content-Type"]; [request setValue:[NSString stringWithFormat:@"%d",[packed_array length]] forHTTPHeaderField:@"Content-Length"]; [request setHTTPBody:packed_array]; //NSHTTPURLResponse *response = nil; NSError *error = nil; NSLog(@"connecting"); NSURLConnection* connection = [[[NSURLConnection alloc]initWithRequest:request delegate:self]retain]; if (connection) { NSLog(@"connection exists"); self.responseData = [[NSMutableData data]retain]; } else { NSLog(@"Connection doesn't exist?"); } NSLog(@"response data: %@",[responseData messagePackParse]); NSLog(@"error: %@",error); } </code></pre> <p>I've attempted the following:</p> <pre><code>NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self]; [connection start]; </code></pre>

    1. CODid you set the `delegate` of the `NSURLConnection`?

    2. COHow do I set the delegate? When I used `[[NSURLConnection alloc]initWithRequest:request delegate:self startImmediately:YES];` it still didn't call the methods. (I NSLogged the name of the method inside every method.)

    3. COSo you already set the `delegate` to `self`. So that's not the problem. Is the URL valid? Try implementing `connection:didFailWithError:` and log the error details.

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.
