STORYBOARD EXCEPTION - Storyboard doesn't contain a view controller with identifier

Question

I am currently developing an iOS application for both iPhone and iPad. I'm trying to show a NavigationController to make a module that shows files. In an iPhone it works just fine, but I can´t get it to work in iPad.

I'm getting the following error:

'Storyboard (<UIStoryboard: 0x919b200>) doesn't contain a view controller with identifier 'FilesNavigation''

and this is the code:

case 10: // Files
{
  UINavigationController *navigationController = [storyboard instantiateViewControllerWithIdentifier:@"FilesNavigation"];

  FilesViewController *filesViewController = [storyboard instantiateViewControllerWithIdentifier:@"Files"];

  [navigationController pushViewController:filesViewController animated:YES];

  self.slidingViewController.topViewController = navigationController;

  break;
}

And in my storyboard I have already set the Storyboard ID for the navigation controller.

>##Custom Class 
>Class: UINavigationController
>##Identity
>Storyboard ID: FilesNavigation

I used this code for another case on the switch/case block for other module and it works for iPad too, its the first time that I have this error.

Answer 1

I figured it out, the problem was that the Storyboard wasn't updating in the device.

1. Uninstall the app from the simulator/iPhone/iPad
2. Product > Clean
3. Build & Run

As stated in @T0m_Twt's answer in this question

Answer 2

In the right pane, in the identity inspector section give a storyboard Id to your Navigation Controller.
