How to get touches when parent view has userInteractionEnabled set to NO in iOS

by

To get a view to let touches pass-through but give its subviews handle touches, let userInteractionEnabled on that view to YES and, instead, use this snippet:

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