I want to the UINavigationBar onto screen when a modal UIView appears, as it does in Reeder.

I'm using the excellent SVWebViewController (https://github.com/samvermette/SVWebViewController) to handle creating a web browser from a shouldStartLoadWithRequest

The animation code is from <http://www.theappcodeblog.com/2011/06/02/iphone-app-animation-tutorial-animate-a-uiview-frame/>

Everything works as in the navigationbar is placed off screen but the space left behind (that I want to animate it into it) is BLACK. The rest of the view/webview is WHITE.

How can I make the space allocated to navbar white, ie the background of the view white?
There is no xib.

I can't find any mention of the navbar in SVWebViewController (only adding a toolbar)

```
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {
    NSLog(@"They clicked: %@", request);

    NSURL *requestURL = [request URL];

    if ([[requestURL scheme ] isEqualToString: @"http"] || [[requestURL scheme] isEqualToString: @"https"]) {

            NSLog(@"Web link %@",requestURL);

            SVModalWebViewController *webViewController = [[SVModalWebViewController alloc] initWithURL:requestURL];
            webViewController.modalPresentationStyle = UIModalPresentationFullScreen;
            webViewController.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;

            webViewController.availableActions = SVWebViewControllerAvailableActionsOpenInSafari | SVWebViewControllerAvailableActionsCopyLink | SVWebViewControllerAvailableActionsMailLink;

            // ios5

            if ([[UINavigationBar class]respondsToSelector:@selector(appearance)]) {

                // Create image for navigation background - portrait
                UIImage *NavigationPortraitBackground = [[UIImage imageNamed:@"navbar_bg_portrait~iPad"]
                                                         resizableImageWithCapInsets:UIEdgeInsetsMake(0, 0, 0, 0)];

                // Create image for navigation background - landscape
                UIImage *NavigationLandscapeBackground = [[UIImage imageNamed:@"navbar_bg_portrait~iPad"]
                                                          resizableImageWithCapInsets:UIEdgeInsetsMake(0, 0, 0, 0)];

                // Set the background image all UINavigationBars
                [[UINavigationBar appearance] setBackgroundImage:NavigationPortraitBackground forBarMetrics:UIBarMetricsDefault];
                [[UINavigationBar appearance] setBackgroundImage:NavigationLandscapeBackground forBarMetrics:UIBarMetricsLandscapePhone];

                [[UINavigationBar appearance] setBackgroundColor:[UIColor whiteColor]];

                // The tintcolor affects the button colour
                UIColor* col = OPAQUE_HEXCOLOR(0xdb536a);
                [[UIBarButtonItem appearance] setTintColor:col];

            } else {

                // Style the Nav Bar ios4
                [webViewController.navigationBar applyCustomTintColor];

            }
            [self presentModalViewController:webViewController animated:YES];

            // -> This code hides the UINavigationBar before animation

            CGRect navBarFrame = webViewController.navigationBar.frame;

            navBarFrame.origin.y = -navBarFrame.size.height;

            // set the position of the bar
            webViewController.navigationBar.frame = navBarFrame;

            // <- end Hide code

            return NO;

        }

    return YES;
}

```
