ios - Google Play 游戏服务 iOS 在登录时崩溃

Question

这是我第一次涉足 xcode 和 objective-c 的世界，所以请多多包涵。我一直在按照 google 开发者网站上列出的步骤在 ios 上实现 google play 游戏服务: https://developers.google.com/games/services/ios/quickstart

第 1-7 步工作正常，我可以使用 GPSignIn 对象登录 Google+:

Finished with auth. 2013-05-28 02:37:19.718 MyApp[2012:907] Success signing in to Google! Auth object is GTMOAuth2Authentication 0x1d56ab40: {accessToken="ya29.AHES6ZQa59aGdKmrWhKSN0ie_S_CqgLfBqKzlmHXU0Cpnxs", refreshToken="1/A8dCPhVKRRgbsM4Gcp4qlkhNJc9SyyTUEVssN3A-Iro", expirationDate="2013-05-28 10:37:19 +0000"}

一旦我实现了第 8 步，尽管我已经实现的 GPGManager 登录函数似乎发生了崩溃:

-(void)startGoogleGamesSignIn
    {
      // The GPPSignIn object has an auth token now. Pass it to the GPGManager.
      [[GPGManager sharedInstance] signIn:[GPPSignIn sharedInstance]
           reauthorizeHandler:^(BOOL requiresKeychainWipe, NSError *error) {
             // If you hit this, auth has failed and you need to authenticate.
             // Most likely you can refresh behind the scenes
             if (requiresKeychainWipe) {
               [[GPPSignIn sharedInstance] signOut];
             }
             [[GPPSignIn sharedInstance] authenticate];
           }];
    }

调试日志:

据我所知，我没有在我的代码中使用任何 NSArray，而且我无法获得正确的调用堆栈。是否还有其他人遇到过类似的问题？

这是因为您忘记在您的 xcode 项目中添加 PlayGameServices.bundle，就像在 https://developers.google.com/games/services/ios/quickstart 上的入门指南中一样。
