Issue with Split View Controller with UITabbarController in iOS7

问题

I am using UISplitViewController inside UITabbarController. Now the problem is that when I am trying to set translucent property of tabbar to NO then it shows an additional bar above the tab bar as shown in picture below.

Your help regarding the problem will be highly appreciated.

Thanks

- (void)setupTabbar {
tabBarController = [[UITabBarController alloc] init];

    tabBarController.tabBar.tintColor = [UIColor whiteColor];

Just add this code on master's viewDidLoad:

self.splitViewController?.extendedLayoutIncludesOpaqueBars = true
