使BWWalkthrough库在启动时启动

Question

我有点被BWWalkthrough库困住了，我试图在应用程序启动时实现这个库。我有两个故事板，主板和SlidesFlow故事板。我将主界面设置为SlidesFlow，并将初始故事板设置为SlidesFlow。我为BWWalkthroughViewController创建了一个视图，为BWWalkthroughPageViewController创建了另一个视图。在我的AppDelegate中，在didFinishLaunchingWithOptions函数中，我使用了以下代码：

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
}

这不管用吗？我是不是遗漏了什么？

Answer 1

发现问题时，似乎根本没有调用didFinishLaunchingWithOptions函数，因为我把我的项目从xcode 7转移到了xcode 8。

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

在这方面：

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