title: Using custom selected and unselected images on UITabBarItem
body: <p>I'm trying to set my own images as selected and unselected images on a UITabBarItem, but no luck. I've tried the following code in the view controller <code>viewDidLoad</code>and <code>viewWillAppear</code>methods, but neither works:</p>
  
  <pre><code>[self.tabBarItem setFinishedSelectedImage:[UIImage imageNamed:@"on_rojo"] withFinishedUnselectedImage:[UIImage imageNamed:@"on"]];
  </code></pre>
  
  <p>What am I doing wrong? I've read also: <a href="https://stackoverflow.com/questions/8547669/ios-5-uitabbaritem-setfinishedselectedimagewithfinishedunselectedimage-not-wo">iOS 5: UITabBarItem setFinishedSelectedImage:withFinishedUnselectedImage: not working / ignored</a>, but I've created my UITabBarController on the IB, not programmatically. Is this the problem?</p>
  
  <p>Thank you in advance,</p>
