How can I make touch events via UIView (similar to event pointers: not in CSS)?

Question

CSS pointer-events:none;allows click events to go through an element. I am curious if there is something similar that I can do in Objective-C on iOS for UIViews.

Here's jsfiddle for example event pointers: none.

Can I somehow achieve the same behavior for UIView by overriding hitTest:withEvent: ? Or maybe there is another way to do this?

Thanks for any help.

#import "TouchTransparentView.h"

@implementation TouchTransparentView

-(id)hitTest:(CGPoint)point withEvent:(UIEvent *)event {
    id hitView = [super hitTest:point withEvent:event];
    if (hitView == self) {
        return nil;
    } else {
        return hitView;
    }
}

@end

:

import UIKit

class PassThroughView: UIView {

    override func hitTest(_ point: CGPoint, with event: UIEvent?) -> UIView? {

        let hitView = super.hitTest(point, with: event)

        if hitView == self {
            return nil
        } else {
            return hitView
        }
    }
}
