In iOS 7 you will not be allowed to set the back button's title to be any longer than 11 characters.

To avoid changing the title of the view controller, but to change the back button's title, you need to do this:

In the previous view controller (the one that will have the next view controller pushed on top of it) you need to set the backBarButtonItem like so:

/**
 *  Notifies the view controller that its view was added to a view hierarchy.
 *
 *  @param  animated                    If YES, the view was added to the window using an animation.
 */
- (void)viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:animated];

    self.title = @"My Title Can Be Long";

    self.navigationItem.backBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"ThisIsLimit"
                                                                             style:UIBarButtonItemStylePlain
                                                                            target:nil
                                                                            action:nil];
}

Now, when the next view controller is pushed on top of it, the back button will be whatever title you put in the backBarButtonItem.
