ios - 如何在 UIAlertController 中为 UITextField 添加边距？

Question

我目前正在实现一个带有文本输入的 UIAlertController。我成功地做到了，没有任何问题。但是，我想更改它的外观，尤其是在文本字段之间添加边距。

This is how it looks right now.

但是我不希望这些文本字段关闭。问题是，如何为文本字段添加边距？

我的代码和尝试:

func createNameChangeSheet(){
        var tvName : UITextField?
        var tvSurname  : UITextField?

        let sheet = UIAlertController(title: "action", message: "alertView", preferredStyle: .Alert)
        let saveAction = UIAlertAction(title: "OK", style: .Default) { (action) in
            self.changeNameSurname((tvName?.text)!,surname: (tvSurname?.text)!)
        }
        let cancelAction = UIAlertAction(title: "Cancel", style: .Cancel, handler: nil)
        sheet.addAction(saveAction)
        sheet.addAction(cancelAction)
        sheet.addTextFieldWithConfigurationHandler { (textField) in
            tvName = textField
            textField.text = self.name

            let margins = UIEdgeInsets(top: 0, left: 0, bottom: 30, right: 0)
            textField.layoutMargins = margins
        }

        sheet.addTextFieldWithConfigurationHandler { (textField) in
            tvSurname = textField
            textField.text = self.surname
        }
        self.presentViewController(sheet, animated: true) {}

    }

在默认情况下，UIAlertController View 是不可自定义的，如果您需要自定义输出，那么我们需要使用自定义 View 或任何 thirdparty lib
