title: UITabBar badge position in iOS7
body: <p>Is there anyway to position UITabBar badge? It looks little displaced in iOS7.
  In iOS7, it is displaced towards next tab bar item.</p>
  
  <p>I have used a custom tab bar item.</p>
  
  <pre><code>UINavigationController *navController = [self.viewControllers objectAtIndex: 0];
  UIViewController *viewController = [navController.viewControllers objectAtIndex:0];
  CustomTabBarItem *tabBarItem = [[CustomTabBarItem alloc] initWithTitle:EMPTY_STRING image: nil tag:2];
  [tabBarItem setImageInsets:UIEdgeInsetsMake(-14.5, 0, 14.5, 0)];
  tabBarItem.customHighlightedImage= [UIImage imageNamed: @"icon_on.png"];
  tabBarItem.customStdImage = [UIImage imageNamed:@"icon_off.png"];
  viewController.tabBarItem = tabBarItem;
  </code></pre>
