UINavigationBar and UINavigationController navbar have different blur

I'm stacking UINavigationBar

on top UINavigationController

, but their blurs don't match, so they don't look right. In UITableViewController

which is the root view UINavigationController

and I have set

self.automaticallyAdjustsScrollViewInsets = NO;
self.edgesForExtendedLayout = UIRectEdgeNone;

      

        
        
        
      

    

in ViewDidLoad

, and it looks closer to the top nav bar, but doesn't match. How can I get these navbars to match? (The navigation bar I'm trying to map includes one that has a segmented control and a Settings menu).
