當我已經在appDelegate.swift中使用Google登錄時，如何將Facebook登錄信息集成到我的ios應用程序中？

Question

我正在編寫一個應用程序，我想讓用戶使用Google或Facebook帳戶登錄。 我目前已經實現了google解決方案，現在我想加入facebook，但是我正為一件事情而苦苦掙扎。

在fb登錄教程中，作者要求准備AppDelegate.swift類中的方法：

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    return FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
}

我的問題是我已經使用谷歌登錄邏輯實現了didFinishLaunchingWithOptions函數：

func application(application: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
 var configureError: NSError?
 GGLContext.sharedInstance().configureWithError(&configureError)
 assert(configureError == nil, "Error configuring Google services: \(configureError)")
 GIDSignIn.sharedInstance().delegate = self

 if let currentUser = GIDSignIn.sharedInstance().currentUser {
     print("user is signed in as "+GIDSignIn.sharedInstance().clientID)

     let sb = UIStoryboard(name: "Main", bundle: nil)

     if let tabBarVC = sb.instantiateViewControllerWithIdentifier("TabController") as? TabController {
     window!.rootViewController = tabBarVC
     }
  } else {
            print("user is NOT signed in")
            let sb = UIStoryboard(name: "Main", bundle: nil)
            if let tabBarVC = sb.instantiateViewControllerWithIdentifier("ViewController") as? ViewController {
                window!.rootViewController = tabBarVC
            }
        }
   return true
}

所以現在怎么辦？ 有什么辦法可以將這兩種方法連接/合並在一起？

謝謝

只需在同一函數中同時添加facebook和google代碼即可。

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

    // Google sign in code
    // ...

    return true
}

返回值（真/假）並不重要。 請參閱本主題以獲取解釋。
