IOS 5 How to change the color of back button in a navigation bar?

Question

I want to change the color of back button of a navigation bar to make it look like this

Answer 1

Set the backBarButtonItem's tintColor:

self.navigationItem.backBarButtonItem.tintColor = [UIColor redColor];

TIP: If you want this to be applied to all UIBarButtonItem instances in your application by default, then you can use the new UIAppearance API to do just that:

[[UIBarButtonItem appearance] setTintColor:[UIColor redColor]];
