I believe you're looking for popViewControllerAnimated function if you want to push (in other words remove or pop) view controller from the stack.
 
Pop != Push. In fact, it's the exact opposite.

Yes, and that's why "push FROM" might been used and I guessed it's because OP asking about opposite action to "push to".

Anyway, the more I read original question, the more confused I get.
