title: UITabBar not showing selected item images in ios 7
body: <p>The icons show fine in ios 6 but not in ios 7. I'm setting the selected state in the viewController viewDidLoad method. When the user selects a tab bar item the image disappears.
  Here is my code:</p>
  
  <pre><code>UITabBar *tabBar = self.tabBarController.tabBar;
  if ([UITabBar instancesRespondToSelector:@selector(setSelectedImageTintColor:)]) {
      [self.tabBarController.tabBar setSelectedImageTintColor:[UIColor whiteColor]];
  }
  UITabBarItem *item0 = [tabBar.items objectAtIndex:0];
  UITabBarItem *item1 = [tabBar.items objectAtIndex:1];
  UITabBarItem *item2 = [tabBar.items objectAtIndex:2];
  UITabBarItem *item3 = [tabBar.items objectAtIndex:3];
  [item0 setTitle:@"Home"];
  [item1 setTitle:@"Calendar"];
  [item2 setTitle:@"News"];
  [item3 setTitle:@"My Events"];
  [item0 setFinishedSelectedImage:[UIImage imageNamed:@"homeIconSelected.png"] withFinishedUnselectedImage:[UIImage imageNamed:@"home2.png"]];
  [item1 setFinishedSelectedImage:[UIImage imageNamed:@"Calendar"] withFinishedUnselectedImage:[UIImage imageNamed:@"CalendarIconSelected"]];
  [item2 setFinishedSelectedImage:[UIImage imageNamed:@"NewsIconSelected"] withFinishedUnselectedImage:[UIImage imageNamed:@"News"]];
  [item3 setFinishedSelectedImage:[UIImage imageNamed:@"EventsIconSelected"] withFinishedUnselectedImage:[UIImage imageNamed:@"Events"]];
  [item1 imageInsets];
  [item2 imageInsets];
  [item3 imageInsets];
  </code></pre>
