I am using a uipopover controller with navigation bar.Actually i want to have navigation bar inside the popover controller. i tried changing the background color of the navigation controller but it didnt look as i expected.The navigation bar buttons seems to be attached with the popover corners.Please find the screenshot attached.Below is my code which i used to create the popover.
WLViewBookmarkViewController * viewBookmarkViewController = [[WLViewBookmarkViewController alloc] initWithStyle:UITableViewStyleGrouped];
viewBookmarkViewController.delegate = self;
UINavigationController *viewBookmarkNavController = [[UINavigationController alloc] initWithRootViewController:viewBookmarkViewController];
viewBookmarkNavController.navigationBar.backgroundColor = [UIColor colorWithRed:9/255.0 green:135/255.0 blue:46/255.0 alpha:1.0];
self.bookmarkPopoverController = [[UIPopoverController alloc] initWithContentViewController:viewBookmarkNavController];
[self.bookmarkPopoverController presentPopoverFromBarButtonItem:bookmarkButtonItem permittedArrowDirections:UIPopoverArrowDirectionDown|UIPopoverArrowDirectionUp
animated:YES];
Please suggest if there are any other way to achieve this.

I created a Xib in where i had a view for the controller which i had to add inside the popover.i added a table view and a navigation bar into the view.
