UIScrollview within UITableViewCell and maintaining scrollview page

UIScrollview within UITableViewCell and maintaining scrollview page

I have a UIScrollView within a UITableViewCell for being able to scroll
through images within a cell. However, as a cell is reused the scroll
position/content is reloaded and therefore the cell doesn't remember what
scroll position (page) it was on when it comes into view again.
What's the best way to have a scroll view within a UITableView cell and
have it maintain position as it comes back into view. The AirBnB app
(https://itunes.apple.com/us/app/airbnb/id401626263?mt=8) seems to have
accomplished this for example.
