Receiving touch events outside bounds

There have been similar questions before and I have referred to Capturing touches on a subview outside the frame of its superview using hitTest:withEvent: and Delivering touch events to a view outside the bounds of its parent view. But they do not seem to answer my particular problem.

I have a custom control with the following structure:

+-------------------------------+
|           UIButton            |
+-------------------------------+
|                          |
|                          |
|        UITableView       |
|                          |
|                          |
+------------------------- +

The custom control overrides the UIButton subclass and adds the UITableView as its subView. The idea is to have the whole control act like a dropdown. When the UIButton is pressed, the UITableView will dropdown and enable selection of a choice.

This all works fine with the hitTest overridden in UIButton as described in the Apple's Q&A link above, if the control is an immediate child of the topmost UIView. However, if the control is in another view hierarchy, the UITableView is not receiving touch events.

The following is the hitTest code used:

override func hitTest(point: CGPoint, withEvent event: UIEvent?) -> UIView? {
    // Convert the point to the target view's coordinate system.
    // The target view isn't necessarily the immediate subview
    let pointForTargetView = self.spinnerTableView.convertPoint(point, fromView:self) 

    if (CGRectContainsPoint(self.spinnerTableView.bounds, pointForTargetView)) {
        // The target view may have its view hierarchy,
        // so call its hitTest method to return the right hit-test view
        return self.spinnerTableView.hitTest(pointForTargetView, withEvent:event);
    }
    return super.hitTest(point, withEvent: event)
}

Edit:

I apologise for not having been able to look at the answers and check if they resolve the issue, due to some other tasks that require immediate attention. I shall check them and accept one that helps. Thanks for your patience.
