【问题描述】：

不幸的是，我在这里阅读了一些类似的问题，但对我并没有太大帮助。

我有一个使用 Swift 的 Xcode 项目，目前，我已经集成了 Twitter 和 Facebook 登录。我也想要谷歌登录。到目前为止，我已经按照这些步骤进行操作，但我遇到了 2 个问题：

didFinishLaunchingWithOptions（在 AppDelegate.swift 中）。我已经将 Facebook 作为返回类型，但在 Google 的文档中它说它需要 return true。怎么做？代码如下：

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


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

//return true -> Expected by Google

return FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions) 

2) openURL func - 这个也期待与 Google 相关的回报，但它目前返回 Facebook（基于他们的文档）：

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

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


    // Required By Google?!
    return GIDSignIn.sharedInstance().handleURL(url, sourceApplication: sourceApplication, annotation: annotation)

所以，我需要帮助来处理这些问题。先感谢您！

【参考方案1】：

解决办法是

func application(app: UIApplication, openURL url: NSURL, options: [String : AnyObject]) -> Bool 
            return
                //facebook
                FBSDKApplicationDelegate.sharedInstance().application(app, openURL: url,
                        sourceApplication: options[UIApplicationOpenURLOptionsSourceApplicationKey] as! String?,
                            annotation: options[UIApplicationOpenURLOptionsAnnotationKey])
                ||

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

【参考方案2】：

在didFinishLaunchingWithOptions 中取一个布尔变量，然后返回该变量，如

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


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

   let b = FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)

   return b 

对于其他问题，你可以这样处理

func application(application: UIApplication, openURL url: NSURL, sourceApplication: String?, annotation: AnyObject) -> Bool 
    return FBSDKApplicationDelegate.sharedInstance().application(application, openURL: url, sourceApplication: sourceApplication, annotation: annotation) 
            || GIDSignIn.sharedInstance().handleURL(url, sourceApplication: sourceApplication, annotation: annotation)

【讨论】：

感谢它的工作。请解释一下 let b = FBSDK... 赋值的目的？？？

【参考方案3】：

对我来说这个很有效

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool 
        // Override point for customization after application launch.
        FIRApp.configure()

        FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)

        GIDSignIn.sharedInstance().clientID = FIRApp.defaultApp()?.options.clientID            
        return true
    

和

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

希望能帮助别人。花了3个多小时。
