Use custom UINavigationBar with initAsRootViewController:

I'm currently doing the following:

    BlogViewController *viewController = [[BlogViewController alloc] initWithBlogPosts];
    UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:viewController];
    [self presentModalViewController:navController animated:YES];
    [viewController release];
    [navController release];

However, I need a way to use a custom UINavigationBar. I've tried using a category like this:

@implementation UINavigationBar (Image)
- (void)drawRect:(CGRect)rect {
    UIImage *image = [UIImage imageNamed: @"toolbar.png"];
    [image drawInRect:CGRectMake(0, 0, self.frame.size.width, self.frame.size.height)];
}
@end

But it doesn't seem to pick that up. Any suggestions? BlogViewController is a subclass of UIViewController.

I used this guy's answer:

[self.navigationController setValue:[[[CustomNavBar alloc]init] autorelease] forKeyPath:@"navigationBar"];

For ios5, you can set the background image directly using setBackgroundImage:forBarMetrics:.

Leave the category implementation around for pre-ios5, and check that the navigation bar responds to the selector above, and you've covered both versions.

I had a similar problem a while ago and then learned that you can actually do this on your app delegate:

After the #import... and before the implementation of the actual appDelegate.

Don't know if it helps but could be a good start point.

 @implementation UINavigationBar (Background)
 -(void)drawRect:(CGRect)rect {
 UIImage *image = [UIImage imageNamed:@"myNavBar.png"];
[image drawInRect:CGRectMake(0,0,self.frame.size.width, self.frame.size.height)];
}
@end

@implementation AppDelegate // code for appDelegate
