我想在内部显示一个包含UIPickerView的警报。可能吗 ？有什么想法吗？

非常感谢！

最后，我使用这个出色的库来制作很酷的自定义提醒：

试试这个：

let alertView = UIAlertController(
        title: "Select item from list",
        message: "\n\n\n\n\n\n\n\n\n",
        preferredStyle: .alert)

    let pickerView = UIPickerView(frame:
        CGRect(x: 0, y: 50, width: 260, height: 162))
    pickerView.dataSource = self
    pickerView.delegate = self

    // comment this line to use white color
    pickerView.backgroundColor = UIColor.lightGray.withAlphaComponent(0.2)

    alertView.view.addSubview(pickerView)

    let action = UIAlertAction(title: "OK", style: UIAlertActionStyle.default, handler: nil)

    alertView.addAction(action)
    present(alertView, animated: true, completion: { _ in
        pickerView.frame.size.width = alertView.view.frame.size.width
    })
