How to change textColor or TextView. Scroll issue when started typing.

[mohinimehetre-silicus]

I have integrated MessageViewController for Chat in my application. I am facing 2 issues right now:

1. I am not able to change textcolor of the textview. I have dark and normal mode and I need to change the textColor based on mode I select.
2. When I start typing into the textview, the tableview in which I am currently displaying the chat messages, scrolls up a little.

Please reply me ASAP as we need to go in production and I have already move here from SlackTextViewController.
