Question

我已经在这里阅读了一些类似的问题，不幸的是，这对我没什么帮助。

我有一个使用Swift的Xcode项目，目前，我已经集成了Twitter＆amp; Facebook登入。我也希望谷歌登录。我到目前为止已按照这些步骤进行了操作，但我已达到了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？这是代码：

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 - 这个也预计谷歌相关的回报，但它目前返回Facebook（根据他们的文档）：

    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，我需要帮助处理这些问题。先感谢您！

Answer 1

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 
}

对于另一个问题，你可以像这样处理它

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)
}

解决方案是

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])
}

对我来说，这个工作

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。正在努力超过3个小时。
