prepareForSeque doesn't fire - objective-c

Question

I have UIViewController with a button, button opens a firstTableViewController -> tabViewController (with 3 tabs) -> one of the tabs has a secondTableViewController -> UIViewController.
Everything is in storyboard.
In firstTableViewController the prepareForSeque works fine. I don't even have didSelectRow...
But on secondTableViewController the prepareForSeque doesn't fire. So I added didSelectRowAtIndexPath as follows. But still the prepareForSegue doesn't work.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[self performSegueWithIdentifier:#"ShowComment" sender:self];
}
-(void) performSegueWithIdentifier:(NSString *)identifier sender:(id)sender
{
[self prepareForSegue:self.storyboard sender:self];
}
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
//When a row is selected, the segue creates the detail view controller as the destination.
//Set the detail view controller's detail item to the item associated with the selected row.
NSLog(#"test");
if ([[segue identifier] isEqualToString:#"ShowComment"]) {
}
}

I found the issue. I did not have an identifier for the cell. Selected the Prototype Cells in the storyboard, in the attributes inspector -> identifier entered 'Cell1'.
In the code:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell1";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
// Configure the cell...
Note *note = [notes objectAtIndex:indexPath.row];
cell.textLabel.text = note.title;
return cell;
}
voila, it worked.
