如何使用Swift在iOS应用中实现配置屏幕？

Question

I'm new in developing iOS apps and I would like to know how can I implement views that appear only on first launch were the user can select his/her own language and nickname before starting the app? I try using navigation controller in my storyboard but no positive respond.

Thanks

1. Add a new UIViewController to your storyboard.
2. Open identity inspector and fill the Storyboard ID like this:

3. Add this code to your main ViewController.swift file:

    override func viewDidAppear(animated: Bool) { super.viewDidAppear(animated) let alreadyLogged = NSUserDefaults.standardUserDefaults().boolForKey("loggedIn") if !alreadyLogged { let sb = UIStoryboard(name: "Main", bundle: nil) let configCtrl = sb.instantiateViewControllerWithIdentifier("configScreen") presentViewController(configCtrl, animated: true, completion: nil) } } 

4. When user finished the setup, do this:

    func finishedSetup() { NSUserDefaults.standardUserDefaults().setBool(true, forKey: "loggedIn") dismissViewControllerAnimated(true, completion: nil) } 

Hope this helps.
