    <p>I have a UITextField which lets the user enter a custom Album name for Facebook Photos. Once textFieldShouldReturn, I take the textField.text and send it to Facebook. Once the completion handler is called, I would like to update my model and reload the data in my tableView.</p> <p>My problem is that some lines of my completionHandler are never called. I marked all lines with the debugger and once I step through the code line-by-line, some of these lines are never called, especially not the tableView reload method.</p> <p>Am I doing something wrong thread-wise? Why is my completionHandler in parts cancelled and never called?</p> <p>Here's my code:</p> <pre><code>-(BOOL)textFieldShouldReturn:(UITextField *)textField { NSString *newAlbumName; newAlbumName = textField.text; NSMutableDictionary* parameters = [NSMutableDictionary dictionary]; [parameters setObject:newAlbumName forKey:@"name"]; [parameters setObject:newAlbumName forKey:@"message"]; FBRequest* request = [FBRequest requestWithGraphPath:@"me/albums" parameters:parameters HTTPMethod:@"POST"]; FBRequestConnection *connection = [[FBRequestConnection alloc] init]; [connection addRequest:request completionHandler:^(FBRequestConnection *connection, id result, NSError *error) { if (!error) { NSDictionary *newAlbum; [newAlbum setValue:newAlbumName forKey:@"name"]; [self.albums addObject:newAlbum]; NSLog(@"created: %@", [newAlbum objectForKey:@"name"]); [self.tableView reloadData]; } else { NSLog(@"Error: %@", error.userInfo); } }]; [connection start]; [textField resignFirstResponder]; [textField removeFromSuperview]; return YES; } </code></pre>

    1. COObviously the lines of code in the body of your `if` statement won't be executed if the condition is not met.

    2. CO@jlehr That is not the issue. the if statement was executed but only a few lines of that statement were executed. The problem, in the end, was how I initialised the NSDictionary. Right would have been: NSDictionary *newAlbum = [[NSDictionary alloc] initWithObjectsAndKeys:newAlbumName, @"name", nil];

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.
