Detect touch on UIButton below UIScrollview

I am working on an app, and wanted to know if the following would be possible. I have a UIScrollView on top of an existing UIView which has UIButtons. The UIScrollView stops the touches from reaching the UIButtons below it.

Can I detect user touches on the UIButtons that is below the UIScrollView? The UIScrollView has clear backgroundColor so the user can still see everything under it.

Any help would be appreciated.

I am not a Swift coder, i could link you all the methods , but I guess you can handle it yourself, unless you can't let me know I will update the answer. However, the solution for you:

First you need to add a UITapGestureRecognizer with a single tap to your UIScrollView.

Detect the tap CGPoint (user touchpoint) inside your tapGesture method: (Objective-c)

CGPoint touchPoint=[gesture locationInView:scrollView];

Then do a check if the touchPoint is inside the view below it with CGRectContainsPoint

bool CGRectContainsPoint(CGRect rect, CGPoint point);

If so, just fire the action, otherwise ignore it. :)
