If you're using the new UISplitViewControllerDelegate for split views in iOS 8, the above methods won't work because the new displayModeButtonItem works a bit differently.

You need to set the font when you're creating the displayModeButtonItem. Assuming you're following Apple's templates this is probably in prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender where you would do something like this:

// From Apple's Template:
NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
NSManagedObject *object = [[self fetchedResultsController] objectAtIndexPath:indexPath];
DetailViewController *controller = (DetailViewController *)[[segue destinationViewController] topViewController];
[controller setDetailItem:object];
controller.navigationItem.leftBarButtonItem = self.splitViewController.displayModeButtonItem;
controller.navigationItem.leftItemsSupplementBackButton = YES;
// New Line to set the font:
[controller.navigationItem.leftBarButtonItem setTitleTextAttributes:@{NSFontAttributeName : [UIFont fontWithName:@"SourceSansPro-Regular" size:14]} forState:UIControlStateNormal];
