当contentsize增加时，scrollview中的子视图不会展开

Question

So I have a view hierarchy as:

UIView > UIScrollView > ContainerView

I have updated the contentSize of the scrollview and that scrolls fine. However, the ContainerView is limited to the original size of the ScrollView and that has made the areas after scroll non clickable.

See image attached. The ContainerView is in yellow color. As you can see, the view is scrolled well but the touches after Select Province is denied. I can't touch elements like Select City, Zipcode

How do I increase the ContainerView's height OR allow the touches beyond visible area

I've tried fixing it with heightConstraint to no avail.

profileScrollView.contentSize = CGSize(width: profileScrollView.frame.width, height: lastView.frame.origin.y + lastView.frame.size.height)

containerViewHeightConstraint.constant = profileScrollView.contentSize.height

Answer 1

Try This

profileScrollView.contentSize = CGSize(width: profileScrollView.frame.width, height: lastView.frame.origin.y + lastView.frame.size.height)

containerViewHeightConstraint.constant = profileScrollView.contentSize.height

self.view.layoutIfNeeded()
