title: UITabbarController showing only first tab
body: <p>I manually added UITabbarController in storyboard which is not root view controller. I added tabbar items to it and set segue relationships. I also set image and title of each tabbar item in code when the first view controller of UITabbarController is about to be presented but no matter what I do only the first item's image is visible. Other items images become visible only when they are tapped and their views are actually loaded. Any inputs how to fix it ?</p>
  
  <pre><code>- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
  // Get the new view controller using [segue destinationViewController].
  // Pass the selected object to the new view controller.
  
  if ([segue.identifier isEqualToString:@"AfterLogin"]) {
  
      UITabBarController *tabBarController = [segue destinationViewController];
      NSArray *tabBarItems = tabBarController.tabBar.items;
  
      UITabBarItem *item1 = tabBarItems[0];
      UITabBarItem *item2 = tabBarItems[1];
      UITabBarItem *item3 = tabBarItems[2];
      UITabBarItem *item4 = tabBarItems[3];
  
      [item1 setImage:[[UIImage imageNamed:@"image1_static"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];
      [item1 setSelectedImage:[[UIImage imageNamed:@"image1_active"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];
      item1 = @"";
      item1.imageInsets = UIEdgeInsetsMake(6, 0, -6, 0);
  
      [item2 setImage:[[UIImage imageNamed:@"image2_static"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];
      [item2 setSelectedImage:[[UIImage imageNamed:@"image1_active"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];
      item2.title = @"";
      item2.imageInsets = UIEdgeInsetsMake(6, 0, -6, 0);
  
      [item3 setImage:[[UIImage imageNamed:@"image3_static"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];
      [item3 setSelectedImage:[[UIImage imageNamed:@"image3_active"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];
      item3.title = @"";
      item3.imageInsets = UIEdgeInsetsMake(6, 0, -6, 0);
  
      [item4 setImage:[[UIImage imageNamed:@"image4_static"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];
      [item4 setSelectedImage:[[UIImage imageNamed:@"image4_active"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];
      item4.title = @"";
      item4.imageInsets = UIEdgeInsetsMake(6, 0, -6, 0);
  }
