swift - tableview自定义单元格按钮单选/取消选择

Question

我已经编码了一段时间了，我一直坚持 TableView 单选/取消选择。我有一个带有自定义单元格的表格 View ，其中有一个按钮。如果我点击一个按钮，底部的另一个按钮也会被选中。例如，当我点击索引为 2 的按钮时，另一个按钮也会被点击。

应该就像当我点击一个按钮时，其他按钮应该被取消选择。

谢谢!

 func QuickReview( sender: UIButton){
    if cell.EventReviewQuickeReviewBtn.isSelected == true {
    cell.EventReviewQuickeReviewBtn.layer.borderColor = UIColor.red
    cell.EventReviewQuickeReviewBtn.backgroundColor = UIColor.white
    cell.EventReviewQuickeReviewBtn.layer.borderWidth = 1
    cell.EventReviewQuickeReviewBtn.isSelected = false
    }
    else {
    cell.EventReviewQuickeReviewBtn.layer.backgroundColor = UIColor.green
    cell.EventReviewQuickeReviewBtn.setTitleColor(UIColor.white, for: .normal)
    cell.EventReviewQuickeReviewBtn.isSelected = true
    }
  }

细胞被重复使用。您需要确保在两种情况下设置/重置完全相同的属性集。

func QuickReview( sender: UIButton){
    if cell.EventReviewQuickeReviewBtn.isSelected {
        cell.EventReviewQuickeReviewBtn.layer.borderColor = UIColor.red
        cell.EventReviewQuickeReviewBtn.backgroundColor = UIColor.white
        cell.EventReviewQuickeReviewBtn.layer.backgroundColor = UIColor.white // or whatever
        cell.EventReviewQuickeReviewBtn.layer.borderWidth = 1
        cell.EventReviewQuickeReviewBtn.setTitleColor(UIColor.red, for: .normal) // or whatever
    } else {
        cell.EventReviewQuickeReviewBtn.layer.borderColor = UIColor.black // or whatever
        cell.EventReviewQuickeReviewBtn.backgroundColor = UIColor.green // or whatever
        cell.EventReviewQuickeReviewBtn.layer.backgroundColor = UIColor.green
        cell.EventReviewQuickeReviewBtn.layer.borderWidth = 3 // or whatever
        cell.EventReviewQuickeReviewBtn.setTitleColor(UIColor.white, for: .normal)
    }

    cell.EventReviewQuickeReviewBtn.isSelected = !cell.EventReviewQuickeReviewBtn.isSelected
}
