如何使用Swift在AppDelegate中導入UIViewController

Question

我有一個名為FirstViewController.swift的UIViewController類，我想在名為MySample的應用程序中的AppDelegate.swift中導入。如何在AppDelegate.swift中導入UIViewController.swift。 我用谷歌搜索，但找不到有效的答案。

提前致謝。

Answer 1

嘗試以下代碼：

    func application(application: UIApplication, openURL url: NSURL, sourceApplication: String, annotation: AnyObject?) -> Bool {
    var rootViewController = self.window!.rootViewController as UINavigationController
    let mainStoryboard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
    var FirstViewController = mainStoryboard.instantiateViewControllerWithIdentifier("StoryBoardID") as FirstViewController
    rootViewController.pushToViewController(FirstViewController, animated: true)

    return true

  }
