我正面臨着上面的書面錯誤。我的應用程序包含兩個登錄方案：1. Facebook登錄（不工作）2.谷歌加登錄（工作正常）

在Facebook登錄的情況下：屏幕開放，我給權限的應用程序 然後它顯示空白的Facebook頁面，只需在頂部添加DONE按鈕。按完成按鈕後，我收到上述錯誤。

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool { 
    FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions) 
    } 

    // Google plus Configuration 
    var configureError: NSError? 
    GGLContext.sharedInstance().configureWithError(&configureError) 
    assert(configureError == nil, "Error configuring Google services: \(configureError)") 

    GIDSignIn.sharedInstance().delegate = self 
    return true 
} 

func applicationDidBecomeActive(_ application: UIApplication) { 
    FBSDKAppEvents.activateApp() 
} 

func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -> Bool { 
    let googleDidHandle = GIDSignIn.sharedInstance().handle(url, sourceApplication: sourceApplication, annotation: annotation) 

    let facebookDidHandle = FBSDKApplicationDelegate.sharedInstance().application(application, open: url, sourceApplication: sourceApplication, annotation: annotation) 

    return googleDidHandle || facebookDidHandle 
} 

@available(iOS 9.0, *) 
func application(_ application: UIApplication, 
       open url: URL, options: [UIApplicationOpenURLOptionsKey: Any]) -> Bool { 
    return GIDSignIn.sharedInstance().handle(url,

你需要如下管理網址scheam：

func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -> Bool { 

    if(url.scheme!.isEqual("fb1212212121223")) { 

    return FBSDKApplicationDelegate.sharedInstance().application(
      application, 
      openURL: url, 
      sourceApplication: sourceApplication, 
      annotation: annotation) 

    } else { 

     return GIDSignIn.sharedInstance().handleURL(url, sourceApplication: sourceApplication, annotation: annotation) 

    } 

}
