title: Go Back to home screen
body: <p>I have created button for home like this:</p>
  
  <pre><code>UIBarButtonItem * addButton=[[UIBarButtonItem alloc] initWithTitle:@"Home" style:UIBarButtonItemStyleBordered target:self action:@selector(GoToHome:)];
      [navItem setLeftBarButtonItem:addButton];
