Question

我已经成功实施了我的应用程序的iOS版Google登录版（Google + Twitter + Facebook版Android工作）。现在我正在尝试添加FB登录，但它似乎与谷歌的登录有冲突。在我看到WebView中成功的FB登录屏幕并按OK - 应用程序崩溃。

AppDelegate的代码

@available(iOS 9.0, *)
    func application(_ application: UIApplication,
                     open url: URL, options: [String: Any]) -> Bool {
        print(url)
        print(options)
        return GIDSignIn.sharedInstance().handle(url as URL!,
                                                     sourceApplication: options[UIApplicationOpenURLOptionsKey.sourceApplication.rawValue] as? String,
                                                     annotation: options[UIApplicationOpenURLOptionsKey.annotation.rawValue])
                || FBSDKApplicationDelegate.sharedInstance().application(application, open: url,
                                                                         sourceApplication: options[UIApplicationOpenURLOptionsKey.sourceApplication.rawValue] as? String,
                                                                         annotation: options[UIApplicationOpenURLOptionsKey.annotation.rawValue])
    }

    func application(_ application: UIApplication,
                     open url: URL, sourceApplication: String?, annotation: Any) -> Bool {
        return GIDSignIn.sharedInstance().handle(url as URL!, sourceApplication: sourceApplication!, annotation: annotation)
                || FBSDKApplicationDelegate.sharedInstance().application(application, open: url, sourceApplication: sourceApplication, annotation: annotation)
    }

这个问题是由Apple“创新”造成的。使用Xcode 8 beta 6，我必须使用

@available(iOS 9.0, *)
    func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {

Firebase身份验证。谷歌+ Facebook =崩溃
