How to turn navigationBar back to nontransparent?

Question

How do I change the navigationBar back to nontransparent in one view after I have made it transparent with this piece of code in AppDelegate.swift :

self.navigationBar.setBackgroundImage(UIImage(), forBarMetrics: UIBarMetrics.Default)
self.navigationBar.shadowImage = UIImage()
self.navigationBar.translucent = true

Answer 1

have you tried:

self.navigationBar.setBackgroundImage(nil, forBarMetrics: UIBarMetrics.Default)
self.navigationBar.shadowImage = nil  
// or
self.navigationBar.barStyle = UIBarStyle.Default 

and of course:

self.navigationBar.translucent = **false**
