    <p>i 'm downloading some files using AFNetworking using a queue. Here is my code:</p> <pre><code>apiClient =[[AFHTTPClient alloc]initWithBaseURL: [NSURL URLWithString:ZFREMOTEHOST]]; for (NSString *element in self.productsArray) { NSURL *url = [NSURL URLWithString:element]; NSURLRequest *request = [NSURLRequest requestWithURL:url]; op = [[AFHTTPRequestOperation alloc] initWithRequest:request]; NSString *documentsDirectory = nil; NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); documentsDirectory = [paths objectAtIndex:0]; NSString *targetFilename = [url lastPathComponent]; NSString *targetPath = [documentsDirectory stringByAppendingPathComponent:targetFilename]; op.outputStream = [NSOutputStream outputStreamToFileAtPath:targetPath append:NO]; [op setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) { } failure:^(AFHTTPRequestOperation *operation, NSError *error) { //failure case NSLog(@"BaaZ File NOT Saved %@", targetPath); //remove the file if saved a part of it! NSFileManager *fileManager = [NSFileManager defaultManager]; [fileManager removeItemAtPath:targetPath error:&amp;error]; if (error) { NSLog(@"error dude"); } if ([operation isCancelled]) { //that doesn't work. NSLog(@"Canceled"); } }]; [op setDownloadProgressBlock:^(NSInteger bytesRead, long long totalBytesRead, long long totalBytesExpectedToRead) { if (totalBytesExpectedToRead &gt; 0) { dispatch_async(dispatch_get_main_queue(), ^{ self.progressView.alpha = 1; self.progressView.progress = (float)totalBytesRead / (float)totalBytesExpectedToRead; NSString *label = [NSString stringWithFormat:@"Downloaded %lld of %lld bytes", totalBytesRead,totalBytesExpectedToRead]; self.progressLabel.text = label; }); } }]; [self.resourcesArray addObject:op]; } for (AFHTTPRequestOperation *zabols in self.resourcesArray) { [apiClient.operationQueue addOperation:zabols]; } </code></pre> <p>the code is working fine on file downloading but i want some cancel functionality so i have a button with an action that has the code below:</p> <pre><code>[apiClient.operationQueue cancelAllOperations]; </code></pre> <p>the operations cancel file but then there are some junk files on the Documents folder. By saying junk i mean file that started downloading i canceled them and the i get a file with the same name but useless can't be opened cause it's damaged.</p> <p>How can i prevent AF from doing that and keep only the completed files when i cancel it?</p> <p>any help would be grateful.</p> <p>Also tried canceling job by job like that:</p> <pre><code>for (AFHTTPRequestOperation *ap in apiClient.operationQueue.operations) { [ap cancel]; NSLog(@"%@",ap.responseFilePath); NSFileManager *fileManager = [NSFileManager defaultManager]; [fileManager removeItemAtPath:ap.responseFilePath error:nil]; } </code></pre> <p>and deleting the junk files but that doesn't work either.</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.

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).
