How to change NavigationBar color?

Question

iOS

How can I change the color of the NavigationBar (the bar at the top of the NavigationController) ?

Answer 1

For the entire application (in the AppDelegate):
For a single controller:

[self.navigationController.navigationBar setBackgroundColor:[UIColor redColor]];

Answer 2

setTintColor:the above does not change the color of the bar, but the color of its elements, for example, UIBarButtonItems located in it. If you need to change the color of the bar itself, use setBarTintColor:.
