Gaming Services iOS SDK

在您整合 Facebook 登入、Facebook 分享或 Facebook Gaming 產品後,除非您停用事件自動記錄功能,否則系統會為事件管理工具自動記錄並蒐集特定應用程式事件。我們建議所有使用 Facebook 登入、Facebook 分享或 Facebook Gaming 產品的應用程式開發人員了解此功能的運作方式。若要進一步了解系統會蒐集哪些資料,以及如何停用事件自動記錄功能,請參閱應用程式事件自動記錄一文。

Gaming Services is available as a new component in the official Facebook SDK for iOS. Using Facebook official SDKs is the recommended approach and makes it easy to access services enabled by Facebook Login for Gaming including the Player Finder and Sharing (for Gaming) experiences.

Prerequisites

  1. Your application needs to enroll in Gaming Services to access features in this document. Follow the instructions to enroll your application.
  2. Make sure you have the minimal version of Facebook iOS SDK or above. Download the latest version.
  3. Ensure your App settings are properly configured for app switch.

Implementation

Facebook Login for Gaming

Facebook Login for Gaming enables a new login method for games. It supports the same implementation and SDK methods as Facebook Login. If this is the first time you're integrating the Facebook SDK into your App, refer to the configuration guide before proceeding.

Instead of receiving public_profile, your application will receive gaming_profile as the default permission. Other requestable permissions include user_friends, email, and gaming_user_picture.


Gaming Graph Domain

After integrating with Facebook Login for Gaming, your application will receive an access token for use on Gaming graph domain (graph.fb.gg), instead of the Facebook graph domain (graph.facebook.com). Read more about gaming graph domain.

You can check if the current User has connected with Facebook Login For Gaming by verifying the Graph Domain to be gaming in the Access Token:

// (c) Facebook, Inc. and its affiliates. Confidential and proprietary.
...
#import <FBSDKCoreKit/FBSDKCoreKit.h>
...
if ([[FBSDKAccessToken currentAccessToken].graphDomain isEqualToString:@"gaming"]) {
  // current user has been migrated to Facebook Login for Gaming
}

Player Finder and Sharing for Gaming

Here's an example from our sample App, which shows how to invoke the Player Finder and Sharing dialogs through the iOS SDK. It also shows the response you can expect from each of them.

// (c) Facebook, Inc. and its affiliates. Confidential and proprietary.

#import <MobileCoreServices/MobileCoreServices.h>
#import <UIKit/UIKit.h>

#import <FBSDKCoreKit/FBSDKCoreKit.h>
#import <FBSDKGamingServicesKit/FBSDKGamingServicesKit.h>
#import <FBSDKShareKit/FBSDKShareKit.h>

#import "Console.h"
