Error on application tried to present a Split View Controllers modally

I'm using storyboards and I want to load a specific set of XIBs, the problem is that I'm getting this error:

'NSInvalidArgumentException', reason: 'Application tried to present a Split View Controllers modally <PlaceHolderViewController: 0x38e890>

In the PlaceHolderViewController I have a button that loads the xib with this code, I have no problem loading the xib from the iPhone but on the iPad I'm having this problem.

This is the code:

- (IBAction)actionButtonConversor:(id)sender {
    ConverterViewController *converterViewController;
    UnitSelectViewController *unitSelectViewController;

    if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
        converterViewController = [[ConverterViewController alloc] initWithNibName:@"ConverterViewController_iPhone" bundle:nil];
        unitSelectViewController= [[UnitSelectViewController alloc] initWithNibName:@"UnitSelectViewController_iPhone" bundle:nil];
        self.navigationController = [[UINavigationController alloc] initWithRootViewController:converterViewController];
        self.navigationController.navigationBar.tintColor = [UIColor colorWithRed:0.0f green:0.48235297203063965f blue:0.63137257099151611f alpha:1];
        [self presentModalViewController:self.navigationController animated:YES];
    } else {
        converterViewController = [[ConverterViewController alloc] initWithNibName:@"ConverterViewController_iPad" bundle:nil];
        unitSelectViewController= [[UnitSelectViewController alloc] initWithNibName:@"UnitSelectViewController_iPad" bundle:nil];
        UINavigationController *masterNavigationController = [[UINavigationController alloc] initWithRootViewController:unitSelectViewController];
        UINavigationController *detailNavigationController = [[UINavigationController alloc] initWithRootViewController:converterViewController];
        masterNavigationController.navigationBar.tintColor = [UIColor colorWithRed:0.0f green:0.48235297203063965f blue:0.63137257099151611f alpha:1];
        detailNavigationController.navigationBar.tintColor = [UIColor colorWithRed:0.0f green:0.48235297203063965f blue:0.63137257099151611f alpha:1];

        self.splitViewController = [[UISplitViewController alloc] init];

        self.splitViewController.delegate = converterViewController;

        self.splitViewController.viewControllers = [NSArray arrayWithObjects:masterNavigationController, detailNavigationController, nil];
        [self presentModalViewController:self.splitViewController animated:YES]; // ERROR comes from here i think
    }

    unitSelectViewController.delegate = converterViewController;
    converterViewController.unitSelectViewController = unitSelectViewController;
}

The problem looks obvious. The following is copied from the UISplitViewController documentation:

"you must always install the view from a UISplitViewController object as the root view of your application’s window. [...] Split view controllers cannot be presented modally."

In other words, what you're seeing is intended behavior.
