How to change UINavigationBar background color from the AppDelegate

Question

I know how to change the UINavigationBar background image by doing     UINavigationBar appearance  setBackgroundImage  UIImage imageNamed   nabbar   forBarMetrics UIBarMetricsDefault     and I know how to set the bar to different colors within each Views      Now I want to change the background color without using an image to a solid color from the app delegate  I do not want to set it each time from each view and I do not want to write a CGRect   I tried    UINavigationBar appearance  setBackgroundColor  UIColor colorWithRed 33 255 0 green 34 255 0 blue 36 255 0 alpha 1 0    but I doesn t work and I cant find a code anywhere that works in the app delegate    Could anyone please point me in the right direction

As the other answers mention  you can use setTintColor   but you want a solid color and that s not possible to do setting the tint color AFAIK   The solution is to create an image programmatically and set that image as the background image for all navigation bars via UIAppearance  About the size of the image  I m not sure if a 1x1 pixel image would work or if you need the exact size of the navigation bar Check the second answer of this question to see how to create the image   As an advice  I don t like to  overload  the app delegate with these type of things  What I tend to do is to create a class named AppearanceConfiguration with only one public method configureAppearance where I set all the UIAppearance stuff I want  and then I call that method from the app delegate

The colour code is the issue here  Instead of using 195 255  use 0 7647 or 195 f 255 f The problem is converting the float is not working properly  Try using exact float value
