在Google Play服务中邀请朋友

我正在使用Google Play游戏服务实现多人游戏function，在Objective-C中创build游戏应用程序。 我遵循https://developers.google.com/games/services/ios/turnbasedMultiplayer上的文档。 在我的应用程序中有两个选项自动匹配和邀请匹配。 自动匹配function正常工作。 但是，邀请匹配不。 我遵循以下代码为此

- (int)minPlayersForPlayerPickerLauncher { return 1; } - (int)maxPlayersForPlayerPickerLauncher { return 2; } - (IBAction)inviteFriendsWasPressed:(id)sender { // This can be a 2-4 player game [GPGLauncherController sharedInstance].playerPickerLauncherDelegate = self; // This assumes your class has been declared a GPGPlayerPickerLauncherDelegate [[GPGLauncherController sharedInstance] presentPlayerPicker]; } 

点击这个button动作跟随屏幕打开看到这里

之后，当我在文本字段中inputemailId时，不会执行search特定用户的操作。

请帮帮我
谢谢

不幸的是，由于Google+不再集成到Play游戏服务中，因此玩家select不再有效： https ： //android-developers.googleblog.com/2016/12/games-authentication-adopting-google.html
