Question

I’m building an iPhone game and I have a UIBarButtonItem that will provide the user with a hint to solve the puzzle when pressed. When the user earns a hint, the text on the UIBarButtonItem is updated to show the current number of hints available. The problem is, the hint count starts at zero and when I update the text and play a little notification sound, it’s still not easily recognizable to the user that they’ve earned a hint as they’re learning to play the game. As such, I’d like to draw some attention to the UIBarButtonItem when I play the notification sound and update the text.

How can I draw attention to a UIBarButtonItem in the nav bar? Is there a way to make it flash? Can I use Core Animation to animate the UIBarButtonItem? Do I have to create a custom UIButton view to accomplish this? I’d prefer not to since that route involves making more art.

Thanks so much in advance for your wisdom!

You can always set the style of the BarButton to “Done” style when an action happens. If your Navbar or Toolbar (whichever houses the button) is set to normal, then the button should turn Blue.
