    <p>I'm happy to be wrong about this, but it looks to me like when you call <code>tableView:didSelectRowAtIndexPath:</code> you set the recipe (ricetta?) in the <code>DetailViewController</code> but I don't see any instruction to tell the <code>DetailViewController</code> to display the new recipe.</p> <p>You have code to update your <code>DetailViewController</code> in <code>viewWillAppear:animated:</code> but this will only happen when the view is going to appear - if your view has already appeared this method won't be executed.</p> <p>I suggest you create a method in <code>DetailViewController</code> called <code>updateRicetta</code> which will look something like:</p> <pre><code>- (void)updateRicetta { lblTitolo.text = [ricetta objectForKey:NAME_KEY]; ingredientiTxtView.text = [ricetta objectForKey:INGREDIENTS_KEY]; descrizioneTxtView.text = [ricetta objectForKey:DESCRIPTION_KEY]; UIImage *img = [UIImage imageNamed:PHOTO_KEY]; fotoImgView.image = img; } </code></pre> <p>You could then call this from tableView:didSelectRowAtIndexPath: -</p> <pre><code>- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { detailViewController.ricetta = [self.ricette objectAtIndex:indexPath.row]; [detailViewController updateRicetta]; } </code></pre> <p>As to the returning <code>nil:</code> my guess is that when <code>viewWillAppear:animated:</code> is called you have not yet selected an entry and therefore ricetta has not yet been set in the <code>DetailViewController</code>.</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).
