    <p>Having a simple Navigation Controller in place (starting the Navigation Based Application project) I created a new View with a XIB file.</p> <p>on my <code>HomeViewController</code> (Home screen with all options as <code>UIButton</code>'s I have:</p> <pre><code>@implementation HomeViewController -(IBAction) optionChoosed:(UIButton *)button { NSString *msg = [NSString stringWithFormat:@"Button: %d", button.tag]; UIAlertView *alert=[[UIAlertView alloc] initWithTitle:@"Hi" message:msg delegate:nil cancelButtonTitle:@"Go away" otherButtonTitles:nil]; switch (button.tag) { case 13: // Simple Search [self loadSimpleSearch]; break; default: [alert show]; break; } [alert release]; } -(void)loadSimpleSearch { SimpleSearchViewController *controller = [[SimpleSearchViewController alloc] initWithNibName:@"SimpleSearchViewController" bundle:nil]; [self.navigationController pushViewController:controller animated:YES]; [controller release]; } </code></pre> <p>witch works great!</p> <p>it Pushes the View into the front of the stack!</p> <p>Now, because in my 2nd view <code>SimpleSearchViewController</code> I have <code>self.title = @"myTitle";</code> I get the Title in the NavigationBar as well the back button (as I have the same setting on the <code>HomeViewController</code>)</p> <p>I thought that the NavigationViewController would handle the pop of the current view, but it does not.</p> <blockquote> <p><strong>What do I have to do</strong>, to pop the <code>SimpleSearchViewController</code>?</p> <p><strong>Where do I use</strong> <code>[self.navigationController popViewControllerAnimated:YES];</code></p> </blockquote> <p>as the view continues there, and <code>ViewDidUnload</code> is never called. </p> <p>My idea was that this should be handle in the first ViewController, the <code>HomeViewController</code> but I have no idea what is the method I should hook to, and I read the documentation and I can't figure it out :-/</p> <p>Any help is greatly appreciated, <strong>thank you</strong>.</p> <p><code>HomeViewController</code></p> <p><a href="http://cl.ly/XNS/Screen_shot_2010-04-21_at_22.38.51.png" rel="nofollow noreferrer">alt text http://cl.ly/XNS/Screen_shot_2010-04-21_at_22.38.51.png</a></p> <p><code>SimpleSearchViewController</code></p> <p><a href="http://cl.ly/YDw/Screen_shot_2010-04-21_at_22.40.00.png" rel="nofollow noreferrer">alt text http://cl.ly/YDw/Screen_shot_2010-04-21_at_22.40.00.png</a></p> <p><code>SimpleSearchViewController</code> after pressing the <em>Back</em> button</p> <p><a href="http://cl.ly/XLO/Screen_shot_2010-04-21_at_22.40.21.png" rel="nofollow noreferrer">alt text http://cl.ly/XLO/Screen_shot_2010-04-21_at_22.40.21.png</a></p> <hr> <p>To add the image from a comment that asks if HomeViewController as the root controller for the NavigationViewController</p> <p><img src="https://i.stack.imgur.com/zVOeb.png" alt="alt text"></p>

    1. COCan you add the code of the SimpleSearchViewController where you set the title ? Are you placing the back button yourself ?

    2. CONo I'm not, this is automatically, all you need to do is set the title in the ViewDidLoad event `self.title = @"Home";`

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).
