UISearchBar animation issue

In your Storyboard, select the problematic controller, look at the Attributes tab and try to edit these settings:

• Under Top Bars
• Under Opaque Bars

I've solved a similar problem by unflagging these settings.

I found what is causing this issue. Seems that the animation gets messed up when you set navigationBar.translucent to NO. If you make your navigationBar translucent, everything should work fine, but this is definitely not an ideal solution. I'm going to try and find a workaround.
