Adding a textfield and send button to the bottom of a tableview controller.

So I basically have no idea where to start or how to do this, but I technically want to place a Textfield with a send button on a tableview controller. Kinda like how it is in iMessage at the bottom of the view controller.

This is a tableview of friends for selection with check marking. Below will be the textfield where a user will place a string and then after selecting friends may tap the send button to send something.

Anyone have any idea how I can do this?

Side-note: I also found something like this but still have no idea how to use it to get the textfield to show up at the bottom of the screen.

I was able to use the other methods though to provide keyboard dismissal which is very useful. ^^

Any feedback will be greatly appreciated! : )
