    <p>I have created a class to generate tickets and when the ticket is generated I want to show it in the table view one by one. I have created a protocol for that class and once the ticket is prepared I send a message to its delegate which is <code>tableView</code> to reload the table view. when the <code>reload</code> method is called on the <code>tableView</code> <code>- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section</code> is being called every time a new ticket is generated but the <code>- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath</code> is not being called every time the ticket is generated but once all the tickets are generated it is being called</p> <p>below is the code</p> <pre><code>- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { if (self.ticketGenerator == nil) { return 0; } else{ return self.ticketGenerator.ticketNumbers.count; } } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; HSEticketView *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[HSEticketView alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]; [cell Tickets:[self.ticketGenerator.ticketNumbers objectAtIndex:indexPath.row]]; } // Configure the cell... return cell; } //to increase the height of the cell - (CGFloat)tableView:(UITableView *)aTableView heightForRowAtIndexPath:(NSIndexPath *)indexPath { return 135; } -(void)background { [self.ticketGenerator GenerateNoOfTickets:[self.enteredNo.text intValue]:self]; } - (IBAction)done:(id)sender { [self.enteredNo resignFirstResponder]; self.enteredNo.hidden = YES; self.label.hidden = YES; self.button.hidden = YES; self.tableView.hidden = NO; [self performSelectorInBackground:@selector(background) withObject:nil]; NSLog(@"dgf"); } #pragma ticketGenrate delgate methods -(void)generationOfTicketCompleated { [self.tableView reloadData]; } </code></pre>

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.
