* Summary:
The accessibility label for UITabBarItems can't be customized. You can set it, and it will read back correctly, but it quickly gets reset back to nil.

* Steps to Reproduce:

Start a sample project with a tab bar.

Add the following method to the app delegate:

- (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController
{
    // Attempt 1
    UITabBarItem *item = [[self.tabBarController.tabBar items] lastObject];
    item.accessibilityLabel = @"Custom Label";
    
    // Attempt 2
    UIView *tabBarButton = [[self.tabBarController.tabBar subviews] lastObject];
    self.tabBarController.tabBarItem.accessibilityLabel = @"Custom Label";
    
    // Attempt 3
    tabBarButton.accessibilityLabel = @"Custom Label";
}

Switch back and forth between tabs.

Use the accessibility inspector to inspect the tab bar item labels and note that they're reset to "First" and "Second" (the item titles).

* Expected Results:

Expected that the accessibility label for at least one of the tab bar items would be "Custom label."

* Actual Results:

The tab bar items all have their accessibility label set to the same thing as their title.

* Regression:

Doesn't work on 4.3 or 5.0b2. Not sure about earlier versions.
