ios - 在 iOS 9 的 alert.addAction 中按下 OK 时如何打开另一个 View Controller

Question

当按下 add.alertAction 中的“确定”时，我想显示一个名为 InViewController 的 View Controller 。

if ((user) != nil) {               
   let alert = UIAlertController(title: "Success", message:   "Logged In", preferredStyle: .Alert)
   alert.addAction(UIAlertAction(title: "OK", style: .Default) { _ in })
   self.presentViewController(alert, animated: true){}
}

Answer 1

let alert = UIAlertController(title: "Success", message: "Logged In", preferredStyle: .Alert)
let action = UIAlertAction(title: "OK", style: .Default) { (action) -> Void in
  let viewControllerYouWantToPresent = self.storyboard?.instantiateViewControllerWithIdentifier("SomeViewControllerIdentifier")
  self.presentViewController(viewControllerYouWantToPresent!, animated: true, completion: nil)
}
alert.addAction(action)
self.presentViewController(alert, animated: true, completion: nil)
