推荐答案

Swift 4.2

对于多项选择，您需要将UITableView属性allowsMultipleSelection设置为 true .

For multiple selections you need to set the UITableView property allowsMultipleSelection to true.

myTableView.allowsMultipleSelection = true

myTableView.allowsMultipleSelection = true

如果您将 UITableViewCell 子类化，则可以在自定义单元格类中覆盖setSelected(_ selected: Bool, animated: Bool)方法.

In case you subclassed the UITableViewCell, you override setSelected(_ selected: Bool, animated: Bool) method in your custom cell class.

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

     if selected {
         contentView.backgroundColor = UIColor.green
     } else {
         contentView.backgroundColor = UIColor.blue
     }
 }
