Modal在Swift中弹出3

Question

我想用swift实现弹出式模式。我必须实现这样的功能，以便根据用户点击的响应（是/否）再弹出一个窗口。如何实现这个 ？ 任何帮助将非常有帮助。

UIAlertController专为此目的而设计。

 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)
