How to make the entire project's navigation bar black in Swift and iOS 9

Question

I want to set the status bar as black for the entire project. I have Pagination, Modal views, Navigation stacks in my project. Is there a way to set the status bar a black for complete project. I've seen this in Android apps. I have tried to set status bar as Light in AppDelegate, have set View-Controllers based navigation bar to NO/YES in plist. Nothing seems to work.

Answer 1

Calling this form application:didFinishLaunchingWithOptions should work.

func setStatusBarBackgroundColor(color: UIColor) {
guard  let statusBar = UIApplication.sharedApplication().valueForKey("statusBarWindow")?.valueForKey("statusBar") as? UIView else {
    return
}

statusBar.backgroundColor = color
}
