Image in the UINvaigationItem - high resolution

I'm setting the title view to my UINavigationItem like this

UIImageView *navigationImage = [[UIImageView alloc] 
                   initWithImage:[UIImage imageNamed:@"header"]];
self.navigationItem.t开发者_如何学PythonitleView = navigationImage;
[navigationImage release];

Can I have 2 images, using the header@2x for high resolution, like it happens with icons?

Yes. Did you try it and it didn't work? Try @"header.png" instead of @"header".
