title: Button in the middle of navigationBar
body: <p>I want to create acustom navigation bar.</p>
  
  <p>I know that we can use UIButton in the middle instead of title in the navigation bar, but can we make something that look like this picture?</p>
  
  <p>As you see we have three different buttons in the middle of this navigation bar. Can you share your idea with me how we can implement such a thing in iPhone?</p>
