用于登录的 facebook openurl ios 9 方法 ios swift

Question

我的应用程序中同时集成了 facebook 和 gmail，但是一旦我为 gmail 登录添加开放 url 功能，facebook 登录就会停止工作。我的应用程序

中有用于打开 url 的代码

func application(application: UIApplication, openURL url: NSURL, sourceApplication: String?, annotation: AnyObject) -> Bool {

    var shouldOpen :Bool = FBSDKApplicationDelegate.sharedInstance().application(application,openURL: url,sourceApplication: sourceApplication,annotation: annotation)

    shouldOpen = shouldOpen ? shouldOpen : GIDSignIn.sharedInstance().handleURL(url,
                                                                                sourceApplication: sourceApplication,
                                                                                annotation: annotation)

    return shouldOpen

}

这适用于 facebook 登录，但是当我为 ios 9 添加 gmail 的 openurl 方法时，问题发生了，即在 facebook 登录后，我们不会重定向回应用程序。在模拟器中，白屏显示在 safari 中。 ios 9

的 gmail 登录代码

func application(app: UIApplication, openURL url: NSURL, options: [String : AnyObject]) -> Bool {
    if #available(iOS 9.0, *) {

        return GIDSignIn.sharedInstance().handleURL(url,
                                                    sourceApplication: options[UIApplicationOpenURLOptionsSourceApplicationKey] as! String?,
                                                    annotation: options[UIApplicationOpenURLOptionsAnnotationKey])
    }
    return true
}

如果我注释掉上面的代码，facebook 登录工作正常我想问题是我必须 return boolean for openurl of facebook in ios 9 .但我不知道该怎么办？ TIA

找到我的答案我需要实现打开的两种方法url像这样

func application(application: UIApplication, openURL url: NSURL, sourceApplication: String?, annotation: AnyObject) -> Bool {

    var shouldOpen :Bool = FBSDKApplicationDelegate.sharedInstance().application(application,openURL: url,sourceApplication: sourceApplication,annotation: annotation)

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

}

func application(app: UIApplication, openURL url: NSURL, options: [String : AnyObject]) -> Bool {
    if #available(iOS 9.0, *) {
        var shouldOpen :Bool = FBSDKApplicationDelegate.sharedInstance().application(
            app,
            openURL: url,
            sourceApplication: options["UIApplicationOpenURLOptionsSourceApplicationKey"] as! String,
            annotation: nil)

        shouldOpen = shouldOpen ? shouldOpen : GIDSignIn.sharedInstance().handleURL(url,sourceApplication: options[UIApplicationOpenURLOptionsSourceApplicationKey] as! String?,
                                                                                    annotation: options[UIApplicationOpenURLOptionsAnnotationKey])

        return shouldOpen
    }
    return true
}

我只需要检查 ios 9 的 facebook 打开 url 方法

编辑 swift 3.0 功能更改

private func application(application: UIApplication, openURL url: URL, sourceApplication: String?, annotation: AnyObject) -> Bool {


    return  FBSDKApplicationDelegate.sharedInstance().application(application,open: url as URL!,sourceApplication: sourceApplication,annotation: annotation)

}

func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {
    if #available(iOS 9.0 , *){
     return FBSDKApplicationDelegate.sharedInstance().application(app, open: url, sourceApplication: "UIApplicationOpenURLOptionsKey", annotation: nil)   

    }

return true
}

我尝试了@Aruk k 的回答，但对我没用

我也遇到了过去 1 month.Followed 所有步骤和教程中的这个问题，但没有任何效果。我在 ios 10 swift 3 中将 facebook 登录与 firebase 集成。最后，我能够成功实现它。我通过在 AppDelegate 文件中进行以下更改来更正它。

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

        FIRApp.configure()
        FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
          return true
    }


    @available(iOS 9.0, *)
    func application(_ application: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any])
        -> Bool {
            var shouldOpen :Bool = FBSDKApplicationDelegate.sharedInstance().application(application,  open: url, sourceApplication:options[UIApplicationOpenURLOptionsKey.sourceApplication] as! String!,annotation: options[UIApplicationOpenURLOptionsKey.annotation])
            return shouldOpen
    }

    // for iOS below 9.0
    func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -> Bool {
        var shouldOpen :Bool = FBSDKApplicationDelegate.sharedInstance().application(application,open: url as URL!,sourceApplication: sourceApplication,annotation: annotation)
        return shouldOpen
    }

Swift 4. Xcode 9. iOS 11. Google 登录 + Facebook 登录。 AppDelegate。

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

    var signedIn: Bool = GIDSignIn.sharedInstance().handle(url, sourceApplication: sourceApplication, annotation: annotation)

    signedIn = signedIn ? signedIn : FBSDKApplicationDelegate.sharedInstance().application(application, open: url, sourceApplication: sourceApplication, annotation: annotation)

    return signedIn
}

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

    var signedIn: Bool = GIDSignIn.sharedInstance().handle(url, sourceApplication: options[UIApplicationOpenURLOptionsKey.sourceApplication] as? String, annotation: options[UIApplicationOpenURLOptionsKey.annotation])

    signedIn = signedIn ? signedIn : FBSDKApplicationDelegate.sharedInstance().application(app, open: url, sourceApplication: options[UIApplicationOpenURLOptionsKey.sourceApplication] as? String, annotation: nil)

    return signedIn
}
