Thank you for the hint in regards to the change. Super useful!

However, I did find that this doesn't always work since lastObject doesn't guarantee to be the UIButton we are after or the accessoryView we care about. Therefore, you will need to do something along the lines of:

        UIView *accessory;
        if (self.accessoryView != nil) {
            accessory = self.accessoryView;
        } else {
            for (UIView *view in self.cellScrollView.superview.subviews) {
                if ([view isKindOfClass:[UIButton class]]) {
                    accessory = view;
                }
            }
        }
