Configure UINavigationBar globally?

Question

I am trying to change instances UINavigationBarglobally using the code below, which is located in DidFinishLaunchingWithOptions(:_);

let navBarApp = UINavigationBar.appereance()
navBarApp.barTintColor = UIColor.mmtRed

but the result;

as you can see in the picture, the colors are different, which should be the same. (The color of the buttons is the one I want my navigation bar to have.)

When I add the code as follows:

navBarApp.isTranslucent = false

result;

The colors are the same right now, but there is a strange gap between UINavigationBarand mainView. So how can I solve this? Any suggestions?

EDIT:

Forgot to mention that I'm using the PageMenu library , maybe this has some effect?

:

let rect = CGRect(x: 0, y: 0, width: 1, height: 1)
UIGraphicsBeginImageContextWithOptions(rect.size, false, 0)
UIColor.redColor().setFill()// your color
