Answer 1

To set a BG image for navigation bar in iOS 5 you can use the below code

if ([self.navigationController.navigationBar respondsToSelector:@selector( setBackgroundImage:forBarMetrics:)]){
[self.navigationController.navigationBar setBackgroundImage:[UIImage imageNamed:@"Navigation.png"] forBarMetrics:UIBarMetricsDefault];
}

But please keep in mind that this wont work in iOS 4. To make it work in both you also need to add a category to UINavigationBar

@implementation UINavigationBar (UINavigationBarCategory)
- (void)drawRect:(CGRect)rect {
UIImage *img = [UIImage imageNamed:@"Navigation.png"];
[img drawInRect:rect];
}
