title: How to increase the height of UITabBar in iOS 7?
body: <p>I'm attempting to set the tab bar's height from within <code>AppDelegate.m</code>'s. When I create a frame with a taller height and set it to the tabbar, there is a part of the tabbar above it's line that is not clickable, although it does show. (It is the area that shows above the tabbar's shadow gradient image that indicating it's top border). It is clearer when there is a custom background image set. </p>
  
  <p>What is a good way to increase the height of the tabbar(preferably from within app delegate) that wouldn't have any unclickable areas.</p>
  
  <p>The <code>applicationDidfinishLaunching</code> method -</p>
  
  <pre><code>- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

      // Make two View Controllers
      UIViewController* firstVC = [UIViewController new];
      UIViewController* secondVC = [UIViewController new];
  
      // Make Tab Bar Controller
      UITabBarController* tabBarController = [UITabBarController new];
      [tabBarController setViewControllers:@[firstVC, secondVC]];
  
      // Set tab's Title &amp; Image
      talksVC.tabBarItem = [[UITabBarItem alloc] initWithTitle:@"First"
                                                         image:[UIImage imageNamed:@"f"]
