ios - 在 AppDelegate 中切换 View (Swift)

Question

我需要根据用户是否注册来设置我的应用程序的起始 View 。这将在 AppDelegate 中完成:

       func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
            if(isUserRegistrated() == true){
                let vc : AnyObject! = self.storyboard.instantiateViewControllerWithIdentifier("isRegistrated")
                    self.showViewController(vc as UIViewController, sender: vc)
            }
            else{
                let vc : AnyObject! = self.storyboard.instantiateViewControllerWithIdentifier("isNOTRegistrated")
                    self.showViewController(vc as UIViewController, sender: vc)
            }
       }

此时我得到了错误:“AppDelegate 类型的值没有 Storyboard 的成员”

有什么结论吗？

示例:

let storyboard = UIStoryboard(name: "MyStoryboardName", bundle: nil)
let vc = storyboard.instantiateViewControllerWithIdentifier("someViewController") as! UIViewController
self.presentViewController(vc, animated: true, completion: nil)
