Float footer to bottom of screen in UITableViewController?

My goal is to recreate a layout that was previously designed on Android. The layout has a header, a list of profiles and controls as a footer at the bottom. My goal is to have the footer float to the bottom of the screen (if there is extra space) or the bottom of the table. Like this:

On Android I had to compromise by making the profiles list a nested scroll view. How could I make the footer float to the bottom on iOS? Or worst case, make it a proper nested scroll view?
