我知道您可以添加文本字段，但是是否可以向 UIAlertController 添加标签？

alertController.addTextFieldWithConfigurationHandler({(textField: UITextField!) in 
            textField.placeholder = "Hyperlink" 
            inputTextField = textField 
            inputTextField?.text="www.google.com" 
        }) 

^^文本域

请您参考如下方法:

有适合​​你的功能:

  func showAlertWith(withLabel: String) { 
    let alert = UIAlertController(title: "Hello!", message: "Hi everybody!\n", preferredStyle: UIAlertController.Style.alert ) 
    let action = UIAlertAction(title: "Ok", style: .default) 
    alert.addAction(action) 
     
    present(alert, animated: true, completion: { 
      //  Add your label 
      let margin:CGFloat = 8.0 
      let rect = CGRect(x: margin, y: 72.0, width: alert.view.frame.width - margin * 2.0 , height: 20) 
      let label = UILabel(frame: rect) 
      label.text = withLabel 
      label.textAlignment = .center 
      label.adjustsFontSizeToFitWidth = true 
      label.minimumScaleFactor = 0.5 
      alert.view.addSubview(label) 
    }) 
  } 

我没有太在意警报中标签的坐标和选项，但我认为您已经清楚了一般含义。
