Disabling vertical scrolling in UIScrollView

Question

There is an option in IB to uncheck vertical scrolling on a scrollview, but it doesnt seem to work.

How can the scrollview be set to only scroll horizontally, and no

Answer 1

A lot of answers include setting the contentOffset to 0. I had a case in which I wanted the view inside the scrollView to be centered. This did the job for me:

public func scrollViewDidScroll(_ scrollView: UIScrollView) {
    scrollView.contentOffset.y = -scrollView.contentInset.top
}
