Mimic ios native form behavior, especially replacing "return" with "Go/Send/Join"

Is it currently possible to duplicate this type of behavior on forms? Here is an example:

In each you notice that depending on the form and function the return key has changed appropriately to a blue button of some kind.

I’ve seen Getting the Keyboard GO button to act like the app Submit was clicked, but it doesn’t seem to be working for me, plus I’m wondering if there’s actually a way to change the text of the button itself or if that’s strictly native.
