Navigation Bar Height

I’m trying to increase the height of the Navigation Bar. It seems that adding a Navigation Bar to the scene is the only way of doing this. However when I do this the height is still greyed out and it puts the added Navigation Bar below the Navigation Controller’s navigation bar.

Can any light be shed on the proper way of accomplishing this?


The above image is what I’m trying to accomplish.

I’ve previously built simple apps and not used a navigation controller. I simply add labels to the top and dismiss the views with the use of a button with a ‘back’ arrow on. Let’s you customise the ‘nav bar’ area as much as you like then by adding whatever labels / images and buttons you wish.
