我怎样才能让一个多可编辑的文本UITextview里面UIAlertController？UITextfield支持单行，我们需要在弹出窗口中创建一个多行文本编辑框。

这是很好的环境…

func popUpController()
{
    let alertController = UIAlertController(title: "\n\n\n\n\n\n", message: nil, preferredStyle: UIAlertController.Style.actionSheet)
    let margin:CGFloat = 8.0
    let rect = CGRect(x: margin, y: margin, width: alertController.view.bounds.size.width - margin * 4.0, height: 100.0)
    let customView = UITextView(frame: rect)
    customView.backgroundColor = UIColor.clear
    customView.font = UIFont(name: "Helvetica", size: 15)
    //  customView.backgroundColor = UIColor.greenColor()
    alertController.view.addSubview(customView)
    let somethingAction = UIAlertAction(title: "Something", style: UIAlertAction.Style.default, handler: {(alert: UIAlertAction!) in print("something")
        print(customView.text)
    })
    let cancelAction = UIAlertAction(title: "Cancel", style: UIAlertAction.Style.cancel, handler: {(alert: UIAlertAction!) in print("cancel")})
    alertController.addAction(somethingAction)
    alertController.addAction(cancelAction)
    self.present(alertController, animated: true, completion:{})
}
