UITableView multiple cell selection from ONE customTapGestureRecognizer

My problem is that right now in my UITableViewDataSource, when I call a function to change the color of the background of the cell AND call another function, several other cells are having their colors changed too. So, when I press my "like" button on a cell, not only is my cell getting highlighted, cells farther down (Have to scroll down), also have their cell highlighted. If I scroll fast down and up, my originally highlighted cell is no longer highlighted (SOMETIMES) too.



I'm currently using a UITableViewDataSource, and inserting into rows using their configuration cellForRowAt. I'm also dequeuing my preference cells with tableview.dequeueReusableCell.



Here is my code:



func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

let category = self.categories[indexPath.row]

let cell = tableView.dequeueReusableCell(withIdentifier: "PreferenceCell") as! PreferenceCell

cell.setCategory(category: category)
cell.selectionStyle = UITableViewCellSelectionStyle.none

let thumbsUpTap = CustomTapGestureRecognizer(target: self, action: #selector(self.onThumbsUp))
thumbsUpTap.category = category;
thumbsUpTap.cell = cell;
cell.thumbsUp.isUserInteractionEnabled = true
cell.thumbsUp.addGestureRecognizer(thumbsUpTap);

let thumbsDownTap = CustomTapGestureRecognizer(target: self, action: #selector(self.onThumbsDown))
thumbsDownTap.category = category;
thumbsDownTap.cell = cell;
cell.thumbsDown.isUserInteractionEnabled = true
cell.thumbsDown.addGestureRecognizer(thumbsDownTap)

return cell;
}


Thank you so much!
