    <p>I am using IOS 5 and Storyboard coding. I have built an application in which i have a tableView connected to a sqlite database with a search bar. When we touch a row, it will take us automatically to another view controller called "Details". I need to pass data from my table view to the details view controller, pass for example the author.title to the labelText.text field. Any ideas?</p> <p>Edited question:</p> <pre><code>- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{ // NSString *Title; Details *dv = (Details*)segue.destinationViewController; author.title = dv.labelText.text; } </code></pre> <p>Partial code:</p> <pre><code>// // Details.m // AuthorsApp // // Created by georges ouyoun on 7/17/12. // Copyright (c) 2012 __MyCompanyName__.

NSLog(@"Everything is ok now !"); } - (void)viewDidUnload { // [self setLabelText:nil]; NSLog(@"U have entered view did unload"); [super viewDidUnload]; [self setLabelText:Nil]; // Release any retained subviews of the main view. } - (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{ // NSString *Title; Details *dv = (Details*)segue.destinationViewController; // author.title = dv.labelText.text; dv.labelText.text = author.title; } /* - (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{ if ([segue.identifier isEqualToString:@"AuthorsCell"]) { [segue.destinationViewController setLabelText:author.title]; } } /* -(void)viewWillAppear:(BOOL)animated { self.labelText.text = author.title; NSLog(@"U have entered the viewWillAppear tag"); // detailsLabel.text = food.description; } */ - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return YES; } - (void)dealloc { [labelText release]; [super dealloc]; } @end </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.
