title: Setting the height of UITabBar
body: <p>I've created a simple custom tabbar by setting the images of each item, as following:</p>
  
  <pre><code>UITabBar *tabBar = self.tabBarController.tabBar;
  UITabBarItem *item0 = [tabBar.items objectAtIndex:0];
  UITabBarItem *item1 = [tabBar.items objectAtIndex:1];
  UITabBarItem *item2 = [tabBar.items objectAtIndex:2];
  
  [item0 setFinishedSelectedImage:[UIImage imageNamed:@"activity_active.png"] withFinishedUnselectedImage:[UIImage imageNamed:@"activity.png"]];
  [item1 setFinishedSelectedImage:[UIImage imageNamed:@"agenda_active.png"] withFinishedUnselectedImage:[UIImage imageNamed:@"agenda.png"]];
  [item2 setFinishedSelectedImage:[UIImage imageNamed:@"settings_active.png"] withFinishedUnselectedImage:[UIImage imageNamed:@"settings.png"]];
  </code></pre>
  
  <p>While this works great, I noticed that there is a black blank space under my tabbar</p>
  
  <p><img src="https://i.stack.imgur.com/i0obB.png" alt="enter image description here"></p>
  
  <p>My images are 44px in height, but I think I have to somehow change the height of my tabbar.</p>
