ios - uitableviewcell 背景颜色上的快速更改标签

Question

我有带有自定义单元格的 UItableview 我需要在选择此行时更改标签背景颜色，但向下滚动时会重复标签颜色

您可以像这样子类化您的 Cell(然后 cellForRow 将不负责更新颜色，只负责设置默认颜色)。

class YourTableViewCellClass: UITableViewCell {

    @IBOutlet weak var yourLabel: UILabel!

    override func setSelected(_ selected: Bool, animated: Bool) {
    if(selected) {

        self.contentView.backgroundColor = UIColor.red //or what you want as your cell bg color
        self.yourLabel.backgroundColor = UIColor.green //or what you want

    } else {

        self.contentView.backgroundColor = UIColor.white //or what you want as your cell bg color
        self.yourLabel.backgroundColor = UIColor.red //or what you want
    }
} }
