Rotate artifacts issue when the keyboard is visible

[kukosk]

Try to rotate your device when the keyboard is visible. There's an issue on the right side of the screen. I'm trying to fix the same issue in my app, and saw this, so I wanted to test if it's the same...

Hi Jakub, do you mean that there is a white block appearing once during the rotation?

Hi, yes, that's what I mean.

I have figured out why this happens during rotation.
Because the [self.view layoutIfNeeded] will schedule the re-layout in the next run loop. The rotation animation just uses the cashed texture, and after that the whole layout get updated.

So, I just force the layout to update before the rotation animation starts. Please check the latest source codes. Though it works, I'm not sure whether there is a great performance hit in real projects by applying this approach.

Thank you, that really helps. Hope it won't have any downsides :)
