以前所有的对话框和textField都运行良好.但不是我不知道这些TextFields如何突然变为单行三联.(就像这里的一些消息......)

    let alert = UIAlertController(title: "Cancel Booking !!", message: "Are you sure you want to cancel your booking?", preferredStyle: .alert)
    alert.addAction(UIAlertAction(title: "No", style: .default, handler: nil))
    alert.addAction(UIAlertAction(title: "Yes", style: .default, handler: self.cancelMessageDialog))
    self.present(alert, animated: true, completion: nil)
