Modal在Swift中彈出3

Question

我想用swift實現彈出式模式。我必須實現這樣的功能，以便根據用戶點擊的響應（是/否）再彈出一個窗口。如何實現這個 ？ 任何幫助將非常有幫助。

UIAlertController專爲此目的而設計。

 let alertController = UIAlertController(title: "Default AlertController", message: "A standard alert", preferredStyle: .Alert) 

     let cancelAction = UIAlertAction(title: "No", style: .Cancel) { (action:UIAlertAction!) in 
      println("you have pressed the No button"); 
      //Call another alert here 
     } 
     alertController.addAction(cancelAction) 

     let OKAction = UIAlertAction(title: "Yes", style: .Default) { (action:UIAlertAction!) in 
      println("you have pressed Yes button"); 
      //Call another alert here 
     } 
     alertController.addAction(OKAction) 

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