iOS 7 Navigation Bar text and arrow color

I want to set background for Navigation Bar to be black and all colors inside it to be white.

So, I used this code :

[[UINavigationBar appearance] setTitleTextAttributes:
     [NSDictionary dictionaryWithObjectsAndKeys:
      [UIColor whiteColor],
      NSForegroundColorAttributeName,
      [UIColor whiteColor],
      NSForegroundColorAttributeName,
      [NSValue valueWithUIOffset:UIOffsetMake(0, -1)],
      NSForegroundColorAttributeName,
      [UIFont fontWithName:@"Arial-Bold" size:0.0],
      NSFontAttributeName,
      nil]];

But back button text color, arrow and bar button have still default blue color.
How to change those colors like on image below?

Behavior from some of the properties of UINavigationBar has changed from iOS 7. You can see in the image shown below :

Two beautiful links I'd like to share with you. For more details you can go through these links :

1. iOS 7 UI Transition Guide.
2. How to Update Your App for iOS 7.

Apple Documentation for barTintColor says :

This color is made translucent by default unless you set the translucent property to NO.

Sample Code :

self.navigationController.navigationBar.barTintColor = [UIColor blackColor];
self.navigationController.navigationBar.tintColor = [UIColor whiteColor];
[self.navigationController.navigationBar 
 setTitleTextAttributes:@{NSForegroundColorAttributeName : [UIColor whiteColor]}];
self.navigationController.navigationBar.translucent = NO;

This one took me about half a day to figure out but this is what worked for me. Inside the rootViewController that initializes the navigationController, I put this code inside my viewDidAppear method:

//set bar color
[self.navigationController.navigationBar setBarTintColor:[UIColor colorWithRed:85.0/255.0 green:143.0/255.0 blue:220.0/255.0 alpha:1.0]];
//optional, i don't want my bar to be translucent
[self.navigationController.navigationBar setTranslucent:NO];
//set title and title color
[self.navigationItem setTitle:@"Title"];
[self.navigationController.navigationBar setTitleTextAttributes:[NSDictionary dictionaryWithObject:[UIColor whiteColor] forKey:UITextAttributeTextColor]];
//set back button color
[[UIBarButtonItem appearanceWhenContainedIn:[UINavigationBar class], nil] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIColor whiteColor], UITextAttributeTextColor,nil] forState:UIControlStateNormal];
//set back button arrow color
[self.navigationController.navigationBar setTintColor:[UIColor whiteColor]];

Swift3, ios 10

To globally assign the color, in AppDelegate didFinishLaunchingWithOptions:

let textAttributes = [NSForegroundColorAttributeName:UIColor.white]
UINavigationBar.appearance().titleTextAttributes = textAttributes

Swift 4, iOS 11

let textAttributes = [NSAttributedStringKey.foregroundColor:UIColor.white]
UINavigationBar.appearance().titleTextAttributes = textAttributes
