UITextView / UILabel bug

[SabatinoMasala]

I stumbled upon this weird bug, where the text in a UILabel (or button) / UITextView will disappear until the animation is completed.

Made a quick demo project for this issue: https://github.com/SabatinoMasala/accessoryview-demo When showing the detail for the first time, the inputAccessoryView will render the text immediately, when you go back and try it again, the text doesn't get rendered until the animation completes.

Any thoughts on this issue?
