iOS 7 : Disable UINavigationBar Translucency For Entire App

Question

Is there a way to disable UINavigationBar Translucency for an entire application?

I\'m aware that using [self.navigationController.navigationBar setTranslucent

Answer 1

See the excerpt from UIKit code documentation:

/*
     New behavior on iOS 7.
     Default is YES.
     You may force an opaque background by setting the property to NO.
     If the navigation bar has a custom background image, the default is inferred 
     from the alpha values of the image—YES if it has any pixel with alpha < 1.0
     If you send setTranslucent:YES to a bar with an opaque custom background image
     it will apply a system opacity less than 1.0 to the image.
     If you send setTranslucent:NO to a bar with a translucent custom background image
     it will provide an opaque background for the image using the bar's barTintColor if defined, or black
     for UIBarStyleBlack or white for UIBarStyleDefault if barTintColor is nil.
     */

Correct Swift 4 solution is

UINavigationBar.appearance().isTranslucent = false
UINavigationBar.appearance().backgroundColor = .white
