在 AppDelegate 中为不是第一个控制器的控制器运行方法

Question

我正在我的应用中配置 Handoff。对于以这种方式构建的应用程序

(Entry Point) -> UINavigationController -> InterestedViewController

够了：

func application(application: UIApplication, continueUserActivity userActivity: NSUserActivity, restorationHandler: ([AnyObject]?) -> Void) -> Bool {
        if let win = self.window {
            let navController = win.rootViewController as! UINavigationController
            let viewController = navController.topViewController as! myViewController

            viewController.restoreUserActivityState(userActivity)
    }
    return true
}

当使用 Handooff 启动应用程序时，此方法在 AppDelegate 中运行，在“myViewController”中启动方法func restoreUserActivityState(activity: NSUserActivity)，一切正常。

问题是我的应用程序以另一种方式构建：

(Entry Point) -> Another ViewController with animated logo -> UINavigationController -> InterestedViewController

所以前面的代码不起作用。看不懂怎么改代码...

Answer 1

func application(application: UIApplication, continueUserActivity userActivity: NSUserActivity, restorationHandler: ([AnyObject]?) -> Void) -> Bool {   // Handoff

    if let win = window {
        let presentationController = win.rootViewController as! PresentationController
        let navController = presentationController.presentedViewController as! UINavigationController
        let viewController = navController.topViewController as! myViewController

        viewController.restoreUserActivityState(userActivity)
    }

    return true
}
