Another tricky one...changing button color in navigation bar

I am referring to this code challenge :http://teamtreehouse.com/library/styling-the-navigation-bar Here's the question : Now we want to change the color of the text of our navigation bar buttons to white. Use the appearance proxy to change the color using [UIColor whiteColor].

And now my code which needs to be debugged :

#import "AppDelegate.h"

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Customize the nav bar
    UIImage *backgroundImage = [UIImage imageNamed:@"navBarBackground"];
[[UINavigationBar appearance] setBarTintColor:[UIColor redColor]];
   [[UINavigationBar appearance] setBackgroundImage:backgroundImage forBarMetrics:UIBarMetricsDefault];
[[UIBarButtonItem appearance] setBarButtonItemColor:[UIColor whiteColor]];


    return YES;
}

@end

This is a tricky one that is on my list of challenges to revise. To change the text color of a button in the navigation bar you can use the setTintColor method.
