body: <p>I am currently trying to change the back button text of a subview that is loaded of a tablecell touch. However even with the way I am trying to implement it it still shows the parents title in the back button.</p>

  <pre><code>UIBarButtonItem *myBarButtonItem = [[UIBarButtonItem alloc] init];
  myBarButtonItem.title = @"Back";
