SFEmptyBackButton

Usage

To remove the title back button is only necessary to invoke:

// Magic happens here
[SFEmptyBackButton removeTitleFromAllViewControllers];

If you only want to delete the title in certain views invokes this:

[SFEmptyBackButton removeTitleFromViewControllers:@[YourViewController.class, AnotherViewController.class];

How It Works

When you have a view with a very long title like this:

And navigate to another view with a very long title the following occurs:

If you delete the title back button invoking:

[[UIBarButtonItem appearance] setBackButtonTitlePositionAdjustment:UIOffsetMake(-100, 0) forBarMetrics:UIBarMetricsDefault];

Most likely this will happen:

But if you rewrite back button with empty title in all views:

UIBarButtonItem *backButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"" style:UIBarButtonItemStylePlain target:nil action:nil];

[self.navigationItem setBackBarButtonItem:backButtonItem];

You get the desired effect:
