How can I add UIButton right underneath navigation bar seamlessly?

Question

I am adding a button in the centre and right underneath my navigation bar. Problem here is that the navigation bar will look like it's cutting off due to its shadow & tint.

How can I incorporate the UIButton so that it looks like it's a part of the navigation bar like this:

____navbar _______   
    l_____|

If I just add a UIButton right underneath the nav bar, it will just look like this:

__________________
     l______|

The button will be used to drag or drop down another uiviewcontroller.

What you need to do is to remove the 1px line that acts as the border or shadow for the UINavigationBar. You can find the way of doing that in the answer here:
