    <p>I feel like I'm missing something basic here, and I would appreciate it if you'd help me pull it all together.</p> <p>Let's say that I have two view controllers... ViewAController and ViewBController.</p> <p>If I wanted to show viewA, I would do this:</p> <pre><code>ViewAController *new_view = [[ViewAController alloc] initWithNibName:@"ViewAController" bundle:nil]; self.viewAController = new_view; [self.view insertSubView:new_view.view atIndex:0]; [new_view release]; </code></pre> <p>If, after showing viewA, I wanted to show viewB controller, I would do this:</p> <pre><code>[self.viewAController.view removeFromSuperview]; ViewBController *new_view = [[ViewBController alloc] initWithNibName:@"ViewBController" bundle:nil]; self.viewBController = new_view; [self.view insertSubView:new_view.view atIndex:0]; [new_view release]; </code></pre> <p>Here is my question...</p> <p>When I load viewA for the first time, viewA's "viewDidLoad" function fires off... It's obviously being loaded for the first time. However, when I remove viewA from the superview, load in viewB, and then later on load viewA again like this:</p> <pre><code>[self.viewBController.view removeFromSuperview]; if ( self.viewAController == nil ) { ViewAController *new_view = [[ViewAController alloc] initWithNibName:@"ViewAController" bundle:nil]; self.viewAController = new_view; [self.view insertSubview:new_view.view atIndex:0]; [new_view release]; } else { [self.view insertSubview:self.viewAController.view atIndex:0]; } </code></pre> <p>viewA's "viewDidLoad" function does NOT fire off. It's as though viewA has been removed from the view, but it's state is sort of saved in memory. When I load viewA again, it just sort of picks up from where it left off. What I really need it to do is load up as though it's loading for the first time again, with "viewDidLoad", etc...</p> <p>I hope I have explained this properly. If anyone could provide some enlightenment, I would appreciate it.</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.
