我有视野。 在双击动作中，我隐藏了它。 但在发布到其他视图之前，它会再次宣布。 下面是代码片段。

func setUpAccessibility() {
                    let tapGesture = UITapGestureRecognizer(target: self, action: #selector(blockLabelViewSwipeGesture))
                    blockContainerView.accessibilityLabel = "Some text label"
                    blockContainerView.accessibilityHint = "Double tap to dismiss"
                    blockContainerView.isAccessibilityElement = true
                    blockContainerView.addGestureRecognizer(tapGesture)
}

    @objc private func blockLabelViewSwipeGesture(_ gestureRecognizer: UISwipeGestureRecognizer { 
             UIAccessibility.post(notification: .layoutChanged, argument: self.headerView)
            //Dismiss view 
            ///DO some work
}
