POLandscape UISplitViewController when using a UINavigationController in the detail

Body
copied!<p>I am developing an iPad/Universal application, and I am facing the problem of handling a UINavigationController as the main detail view in a UISplitViewController. What I want to know is how to add the default side controller button to the detail controller when in landscape orientation.</p> <h3>Definition</h3> <p>The split view controller has been defined this way:</p> <pre><code>splitViewController = [[UISplitViewController alloc] init]; SideController *root = [[[SideController alloc] init] autorelease]; DetailController *detail = [[DetailController alloc] init]; InserisciDatiController *calcolo = [[[InserisciDatiController alloc] initWithNibName:@"InserisciDatiNuovi" bundle:[NSBundle mainBundle]] autorelease]; UINavigationController *rootNav = [[[UINavigationController alloc] initWithRootViewController:root]autorelease]; UINavigationController *calcoloNav = [[[UINavigationController alloc] initWithRootViewController:calcolo] autorelease]; splitViewController.viewControllers = [NSArray arrayWithObjects:rootNav, calcoloNav, nil]; splitViewController.delegate = detail; </code></pre> <p>and later on I release all the releasable objects. I am using the <code>SideController</code> as a sort of index for the detail controller. It has a table view, and clicking each row I update the main view controller of the detail. Each new controller is always an instance of UINavigationController.</p> <h3>Update the detail</h3> <pre><code>myAppDelegate *delegate = (myAppDelegate *)[[UIApplication sharedApplication] delegate]; UINavigationController *nav = (UINavigationController *)[delegate.splitViewController.viewControllers objectAtIndex:1]; [nav setViewControllers:[NSArray arrayWithObjects:controller, nil]]; </code></pre> <p>I use this piece of code to update the detail controller, when the user taps a row in the side view controller.</p> <h3>Handle landscape orientation</h3> <p>I'd like to know how to handle the landscape orientation, when I want to add the default toolbar button to display the hidden side view controller. What I am not able to do is getting the toolbar of the detail navigation controller to add the button using this method:</p> <pre><code>- (void)splitViewController:(UISplitViewController*)svc willHideViewController:(UIViewController *)aViewController withBarButtonItem:(UIBarButtonItem*)barButtonItem forPopoverController:(UIPopoverController*)pc </code></pre> <p>And also, when I push a new controller to the navigation controller the default back button will appear in the toolbar. In this case how should I handle the button creation?</p> <h2>Update</h2> <p>Please, do not tell me that no-one has ever had this kind of problem! How do you develop iPad apps? Sob ...</p>
