        if let embedTextView = gesture.view as? EmbedTextView {
            textMode()
            self.textTools.editingTarget = embedTextView
        }
    }

    self.stampFrame.borderColor = UIColor.black


}

Answer 1

要在集合视图中取消选择：-

collectionView.deselectItem(at: indexPath, animated: false)

Answer 2

// Get index from tap gesture , for did deselect

@objc func tapBlurButton(_ sender: UILongPressGestureRecognizer) {

        let location = sender.location(in: collectionView) // point of touch in collectionView
        if let indexPath = collectionView.indexPathForItem(at: location) { // indexPath of touch location
            let indexPaths = IndexPath(item: indexPath , section: 0)
            collectionView.selectItem(at: indexPaths, animated: true, scrollPosition: .top)
            collectionView.delegate?.collectionView!(collectionView, didDeselectItemAt: indexPaths)
    }
}

// Hope it works for you! thanks
