title: How to customize UINavigationBar
body: <p>I'm struggling in <strong>custom UINavigationBar</strong>. The reason i want to customize is because there is same action that can be occur in different view controller. I post some images as an example.</p>
  
  <p><img src="https://i.stack.imgur.com/JaZX8.png" alt="Navigation Bar - 1">
  <img src="https://i.stack.imgur.com/jpbV2.png" alt="Navigation Bar - 2">
  <img src="https://i.stack.imgur.com/oMUyL.png" alt="Navigation Bar - 3"></p>
  
  <p>As you can see from the images above. I think you get what i mean. I have been trying and searching, but i don't get the answer i wanted. Furthermore, i have tried using <strong>UIView</strong> to accomplish this, it worked, but i don't think it is correct way to do this. Therefore, i need help from you guys to lead me to the right path. :) :) Thank you.</p>
