Changing the UINavigationBar background image

Question

I\'ve been trying to change the background image of the UINavigationBar of my application. I tried several ways. First I added to my AppDelegate class the following code:

Another way to set an image in navigation bar is,

UIImage* logo = [ UIImage imageNamed:@"Logo.png" ];
UIImageView* logoView = [[[UIImageView alloc] initWithImage:logo] autorelease];
self.navigationItem.titleView = logoView;

This will not change whole navigation bar background. But adds a background image centered on the navigation bar, which is sometime more intended (what I was looking for).
