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; } Source: http://cocoaheads.tumblr.com/post/2130871776/ignore-touches-to-uiview-subclass-but-not-to-its

UIGestureRecognizer blocks subview for handling touch events
