When the parent view has userInteractionEnabled=NO, its subviews will not accept touch events even if their userInteractionEnabled property is set to YES.

Is there any way to still get touch events in subviews?

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;
}
