Ios 如何将当前选中的字符串分配给detailLabel UITableViewCell？

Swift编译错误“text”不可用：在iOS 7及更早版本中不推荐使用的API在Swift中不可用

编辑： @IBVAR弱var详细标签：UILabel

但是,

我遇到过这样的情况，我如何修复这些行来证明所有iOS版本？

detailLabel是UILabel吗？Style:Right Detail，UITableViewCell当我将其修复为UILabel时，但现在我的编译终止了，如：libc++abi.dylib：以NSException LLDb类型的未捕获异常终止我不明白的是，在可以访问单元格本身的方法之外，您如何访问单元格的正确细节？每个单元格的detailLabel将具有不同的值。或者你使用的是静态单元格？表视图内容：静态单元格，我使用的是正确的细节和推送segue动态原型来选择游戏。当用户返回静态页面detailLabel:UILabel时，需要由用户选项更新。我已经修复了它，但现在编译终止了，因为我在上面的主题编辑中提到了它。>以NSException lldb类型的未捕获异常终止

override func viewDidLoad() {
  super.viewDidLoad()
  **detailLabel.text = game**
}

@IBAction func selectedGame(segue:UIStoryboardSegue) {
  if let gamePickerViewController = segue.sourceViewController as? GamePickerViewController,
    selectedGame = gamePickerViewController.selectedGame {
    **detailLabel.text = selectedGame**
    game = selectedGame
  }
}
