  <p>I want to create a custom tab bar like the image shows. I don't know how to begin subclassing <code>UITabBar</code> to get this result.
  What If I simply have a Root <code>UIViewController</code>, and create the perception of tab bar through <code>interface builder</code> (a UIView, images, circle button, etc) and add <code>ContainerView</code>'s for map and list <code>UIViewController</code>'s? What are the downfalls to this approach, if any? Resizing issue (looks good on iPhone 6 but not iPhone X) since there is no tab bar to dynamically resize maybe? </p>
