How to enlarge hit area of UIGestureRecognizer?

Question

I'm using few gesture recognizers on some views, but sometimes views are too small and it's hard to hit it. Using recognizers is necessary, so how can I enlarge hit area?

Swift version of @rmaddy answer:

override func hitTest(_ point: CGPoint, with event: UIEvent?) -> UIView? {
    let frame = self.bounds.insetBy(dx: -20, dy: -20);
    return frame.contains(point) ? self : nil;
}
