    <p>I am using if-modified-since in the HTTP header to decide if I should download file. App was tested and everything was OK, but now I am getting errors when I ask my NSHTTPURLResponse instance <code>response.statusCode</code> or <code>[[response allHeaderFields] objectForKey:@"Last-Modified"]</code>. </p> <p>It seems to be just NSURLResponse. What are the possible reasons? </p> <p>I've read<a href="https://stackoverflow.com/questions/7396966/when-is-a-nsurlresponse-not-a-nshttpurlresponse">this topic</a> but the problem still is not clear for me. Thanks in advance! UPD: some code:</p> <pre><code> NSURL *url = [NSURL URLWithString:urlString]; NSFileManager *fileManager = [NSFileManager defaultManager]; NSMutableURLRequest *myRequest = [NSMutableURLRequest requestWithURL:url]; [myRequest setHTTPMethod:@"GET"]; NSDateFormatter *df = [[NSDateFormatter alloc] init]; df.dateFormat = @"EEE',' dd MMM yyyy HH':'mm':'ss 'GMT'"; df.locale = [[NSLocale alloc] initWithLocaleIdentifier:@"en_US"]; df.timeZone = [NSTimeZone timeZoneWithAbbreviation:@"GMT"]; [myRequest addValue:[df stringFromDate:lastModifiedLocal] forHTTPHeaderField:@"If-Modified-Since"]; myRequest.cachePolicy = NSURLRequestReloadIgnoringLocalAndRemoteCacheData; NSHTTPURLResponse *response=nil; NSError* error = nil; NSData* data = [NSURLConnection sendSynchronousRequest:request returningResponse:&amp;response error:&amp;error]; if (error) { NSLog(@"Error sending request: %@", [error localizedDescription]); } //As was advised NSHTTPURLResponse* newResp = (NSHTTPURLResponse*)response; //crash here NSLog(@"%d", newResp.statusCode); </code></pre> <p><strong>UPD:</strong> Error in code - myRequest and request are different variables. Problem solved.</p>

    1. COWhat is the result for `data` after the `sendSynchronousRequest:returningResponse:error:`? Also, Why not try passing in an actual `NSError` pointer so if something goes wrong you might possibly know what it is, by logging `error.localizedDescription`?

    3. COThere was a mistake because of my stupid unconcentration - `[myRequest addValue:[df stringFromDate:lastModifiedLocal] forHTTPHeaderField:@"If-Modified-Since"]; myRequest.cachePolicy = NSURLRequestReloadIgnoringLocalAndRemoteCacheData;` and `NSData* data = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];` after it, another variable with local URL, so no HTTP there. Sorry. Will approve most complete answer.

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.
