UINavigationBar.appearance (). Translucent creates a large empty space

Question

UPDATE 2 : I still hope to get some help in resolving this problem, so I will now clarify my question a bit, that I narrowed it down better.

My hierarchy is UIViewControlleras follows:

The filter view is displayed if the user touches the filter icon and selects the type of lift. The image on the left is what it looks like without the filter selected, and the correct image looks as if the filter is selected. The navigation area (highlighted in green) is what I'm trying to create.

This is what I just can't understand. If I add these two things:

UINavigationBar.appearance().translucent = false
UINavigationBar.appearance().barTintColor = UIColor(hexString: "232B35")

then a space appears between the navigation area and the filter view:

true, , barTintColor .

, UINavigationBar UIViewController. UINavigationItem, .

: , UINavigationBar.appearance().translucent = false ( , , )?

. !

, : . UIViewController ThemeManager struct , , :

static func applyTheme(theme: Theme) {

    // set the background color
    sharedApplication.delegate?.window??.backgroundColor = UIColor(hexString: "232B35")

    UINavigationBar.appearance().translucent = false // these are the offenders
    UINavigationBar.appearance().barTintColor = UIColor(hexString: "232B35")


    // first, set backgroundimage to nothing
    UINavigationBar.appearance().setBackgroundImage(
      UIImage(),
      forBarPosition: .Any,
      barMetrics: .Default)

    // and also set shadowimage to nothing
    UINavigationBar.appearance().shadowImage = UIImage()

    UIStatusBarStyle.LightContent
    UILabel.appearance().textColor = UIColor(hexString: "768DAA")
    }
  }
