The problem appears to be with hitTest/pointInside. I’m guessing the cell is returning NO from pointInside if the touch is on the part of the button that is outside the cell and thus the button doesn’t get hit tested. To fix this you have to override pointInside on your UICollectionViewCell subclass to take the button … Read more
I had a very similar problem and found my solution in this SO question. In summary, set yourself as the delegate for your UIGestureRecognizer and then check the targeted view before allowing your recognizer to process the touch. The relevant delegate method is: – (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch
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
Probably the best way to do this is to override hitTest:withEvent: in the view that you want to be ignoring touches. Depending on the complexity of your view hierarchy, there are a couple of easy ways to do this. If you have a reference to the view underneath the view to ignore: – (UIView *)hitTest:(CGPoint)point … Read more
