使BWWalkthrough库在启动时开始

我有点卡在BWWalkthrough库，我试图在应用程序启动时实现。我有两个故事板Main One和SlidesFlow故事板。我将主界面设置为SlidesFlow，并将初始故事板设置为SlidesFlow。我确实为BWWalkthroughViewController创建了1个视图，为BWWalkthroughPageViewController创建了另外4个视图。在我在didFinishLaunchingWithOptions功能的AppDelegate我用下面的代码：使BWWalkthrough库在启动时开始

private func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool { 
    // Override point for customization after application launch. 

    // Get view controllers and build the walkthrough 
    let stb = UIStoryboard(name: "SlidesFlow", bundle: nil) 
    let walkthrough = stb.instantiateViewController(withIdentifier: "SlideShow") as! BWWalkthroughViewController 
    let page_zero = stb.instantiateViewController(withIdentifier: "Slide_1") 
    let page_one = stb.instantiateViewController(withIdentifier: "Slide_2") 
    let page_two = stb.instantiateViewController(withIdentifier: "Slide_3") 
    let page_three = stb.instantiateViewController(withIdentifier: "Slide_4") 

    // Attach the pages to the master 
    walkthrough.delegate = self 
    walkthrough.addViewController(page_one) 
    walkthrough.addViewController(page_two) 
    walkthrough.addViewController(page_three) 
    walkthrough.addViewController(page_zero) 

    return true 
}

不应该工作的呢？我错过了什么吗？

分配'window.rootViewController = walkthrough'前'返回TRUE' –

它仍然无法正常工作。 – Netra

检查所有viewContoller是否已初始化，或者演练是否不为零。 –

发现问题，似乎didFinishLaunchingWithOptions函数根本没有被调用，我认为是因为我将项目从xcode 7转移到了xcode 8.所以如果有人正在努力解决类似问题，只需替换旧的didFinishLaunchingWithOptions函数

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool

与此：

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions:[UIApplicationLaunchOptionsKey : Any]? = nil) -> Bool
