title: UITabBarItem Change Image Height and Width
body: <p>I have a UITabBarItem without a title and only an image. I was wondering how I can change the image size so it can take up the whole UITabBarItem. </p>
  
  <p>I searched all over the internet but found nothing.</p>
  
  <p>I tried:</p>
  
  <pre><code>UIStoryboard *storyBoard = [UIStoryboard storyboardWithName:@"Main_Storyboard" bundle:nil];
  UITabBarController *tabBarController = [storyBoard instantiateViewControllerWithIdentifier:@"tab"];
  UITabBar *tabBar = tabBarController.tabBar;
  UITabBarItem *tabBarItem1 = [tabBar.items objectAtIndex:0];
  UITabBarItem *tabBarItem2 = [tabBar.items objectAtIndex:1];
  UITabBarItem *tabBarItem3 = [tabBar.items objectAtIndex:2];
  
  tabBarItem1.imageInsets = UIEdgeInsetsMake(0, -10, -6, -10);
  </code></pre>
  
  <p>but nothing changed.</p>
  
  <p>Thank you!</p>
