我已经问过这个问题，但没有更多解决方案。我挣扎了超过1天。我是初学者。请帮帮我。
我有两个屏幕。一个用于登录，其中有fb, google plus个登录。另一个屏幕是注册，它具有相同的fb, google plus注册。现在，当用户第一次使用fb或google plus按钮登录我的注册屏幕时。
当用户退出并再次转到sign up屏幕时，如果他们尝试登录，则UIAlert将显示他们已经注册。
请参阅以下代码以供参考。

需要！
但我需要的是，当新用户或注册用户在我的注册屏幕中按fb,google plus时，他们应该转到我的项目。
对于已经注册的新用户或旧用户，不应该说出警告＆＃34;在我的注册屏幕中。
当任何已注册或未注册的用户在注册屏幕中按下fb, google登录按钮时，他们应该已登录并应该进入我的应用程序。
我尝试过更改UIAlert或删除错误消息，但是当我输入时，我收到的错误为internal server error。此代码使用了一些AFnetworking。
请帮帮我，我挣扎了3个多小时。如果我的解释不清楚，请发表评论，以便我重写。
每次用户通过sign in屏幕登录都没有问题。但是，当用户注册或新用户按下fb, google plus按钮进行登录时，他们应该可以在我的应用中输入...就像我的sign in屏幕
感谢。
