UIScrollView with sticky footer UIView and dynamic height content

Question

Challenge time!

Imagine we have 2 content views:

1. UIView with dynamically height content (expandable UITextView) = RED
2. UIView as a footer = BLU

Answer 1

If I understand whole task, my solution is put "red" and "blue" views to one container view, and in the moment when you know size of dynamic content (red) you can calculate size of container and set scrollView content size. Later, on keyboard events you can adjust white space between content and footer views
