Question

我想保存按下保存按钮时要保存的文本中输入内容的数据。这是我的代码：

@IBAction func buttonTappedToSetAReminder(sender: AnyObject) {

     let alertController = UIAlertController(title: "Reminders", message: "", preferredStyle: UIAlertControllerStyle.Alert)

     let saveAction = UIAlertAction(title: "Save", style: UIAlertActionStyle.Default, handler: {
          alert -> Void in

          _ = alertController.textFields![0] as UITextField

     })

     let cancelAction = UIAlertAction(title: "Cancel", style: UIAlertActionStyle.Default, handler: {
          (action : UIAlertAction!) -> Void in

     })

     alertController.addTextFieldWithConfigurationHandler { (textField : UITextField!) -> Void in
          textField.placeholder = "Put a reminder!!!"
     }

     alertController.addAction(saveAction)
     alertController.addAction(cancelAction)

     self.presentViewController(alertController, animated: true, completion: nil)

}

Answer 1

let textField = alertController.textFields![0] as UITextField
// do something with textField.text

Answer 2

似乎NSUserDefaults / UserDefaults是一个选项：

斯威夫特2：

let textField = alertController.textFields![0]
NSUserDefaults.standardUserDefaults().setObject(textField.text, forKey: "text")

斯威夫特3：

let textField = alertController.textFields![0]
UserDefaults.standard.set(textField.text, forKey("text")
