Adding a UINavigationController to my segue.destinationViewController in Objective-C

Question

I have a SplitViewController based application that calls other UIViewController users to display them by replacing in the details section ...

I send them parameters, information, objects, and everything works fine using segues from MasterViewController

But some of my UIViewControllers interact with other UIViewControllers using Segues, so to make them work fine, I need to embed them in the UINavigationController

my question is:

How to add a UINavigationController to my segue.destinationViewController when segue is executed for:

• Passing them my parameters from masterViewController
• Allow my UIViewControllers to interact with other ViewControllers using Segues

I thought in the solution: -Producing parameters by creating custom delegates or protocols in MasterViewController -UINavigationControllers Institution adds them to the development mode in the storyboard, embedding my UIViewControllers in them

but I need to set a UISplitViewController delegate to my destinationViewController to display a button that displays the MasterViewController in portrait mode ...

if I set this in the prepareForSegue method, having a UINavigationControllers holding my ViewControllers, I will set the UISplitViewController delegate instead of the UINavigationController

in advance for help

EDIT: this was the way I found to solve it:

At first I assigned IBAction to the button, if my device is not an iPad, it will do the usual seg ...

- (IBAction)openExecutives:(id)sender { if ([[[UIDevice currentDevice]model] hasPrefix:@"iPad"]) { UsersListVC *rightViewController = [self.storyboard instantiateViewControllerWithIdentifier:@"UsersListVC"]; [self showSplitViewController:rightViewController]; } else [self performSegueWithIdentifier:@"viewSceneExecutives" sender:self]; } 

This is a feature that I developed to create a SplitView with my custom granularity ...

 -(void)showSplitViewController:(id)rightViewController{ UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:@"iPad2" bundle: nil]; UINavigationController *leftNavController; UINavigationController *rightNavController; MainMenuVC *leftViewController = [mainStoryboard instantiateViewControllerWithIdentifier:@"MainMenuVC"]; leftNavController = [[UINavigationController alloc] initWithRootViewController:leftViewController]; rightNavController = [[UINavigationController alloc] initWithRootViewController:rightViewController]; leftNavController.toolbarHidden = FALSE; rightNavController.toolbarHidden = FALSE; UISplitViewController *splitViewController = [[UISplitViewController alloc] init]; splitViewController.viewControllers = [NSArray arrayWithObjects:leftNavController, rightNavController, nil]; splitViewController.delegate = rightViewController; self.view.window.rootViewController = splitViewController; } 

All I did was redraw the splitViewController from the start, creating a function that requires a parameter (UIViewController)

You must configure the controllers in IB built into the navigation controllers. When you want to access the content controller from your main view controller, you can simply use the topViewController navigation controller property to get the link. So, in prepareForSegue: you can do something like this:

 - (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender { UINavigationController *dest = (UINavigationController *)segue.destinationViewController; self.detailViewController = (DetailViewController *)dest.topViewController; self.splitViewController.delegate = self.detailController; }
