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

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

Vin's answer worked great for me. Here is the same solution for C# developers using Xamarin.iOS/MonoTouch:

var navigationBar = NavigationController.NavigationBar; //or another reference
navigationBar.BarTintColor = UIColor.Blue;
navigationBar.TintColor = UIColor.White;
navigationBar.SetTitleTextAttributes(new UITextAttributes() { TextColor = UIColor.White });
navigationBar.Translucent = false;
