Swift 5

subview.swift

override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
    super.touchesBegan(touches, with: event)
    self.next?.touchesBegan(touches, with: event)
}

If you're unsure if you should call super.touchesBegan(touches, with: event), refer to the doc discussion.

superview.swift

override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
    // handle
}

Subclassing and waiting for touchesBegan won't help you, as it won't get called.
I subclassed UIWebView and just "leeched" onto its gesture recognizers in subviews 2 levels deep (you could go recursively but thats enough for iOS6-7). Then you can do whatever you want with the touch location and gesture recognizer's state. 

for (UIView* view in self.subviews) {
    for (UIGestureRecognizer* recognizer in view.gestureRecognizers) {
        [recognizer addTarget:self action:@selector(touchEvent:)];
    }
    for (UIView* sview in view.subviews) {
        for (UIGestureRecognizer* recognizer in sview.gestureRecognizers) {
            [recognizer addTarget:self action:@selector(touchEvent:)];
        }
    }
}

  1. Subclass UIWebView in your code and then implement touchesBegan in your class.
  2. Add the subclassed webview as a subview of your UIView.

  3. Call super in the subclassed UIWebView

    - (void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event 
{
    [super touchesBegan: touches withEvent: event];
}
