Question

我是初次使用以下代码的iPhone编程我登录Facebook并从Facebook获取数据，如电子邮件ID，用户名后我发送到服务器的电子邮件。但我的问题是，如果已经登录Facebook意味着自动调用它 - （void）loginViewFetchedUserInfo：（FBLoginView *）loginView user：（id）此方法用户发送到服务器的电子邮件ID。我不想这样，如果我点击按钮然后我只想获取Facebook电子邮件ID并发送到服务器。请任何人都可以知道如何解决它。

        FBLoginView *fbLoginview =

            fbLoginview.frame = CGRectMake(30, 10, 200, 30);
            for (id obj in fbLoginview.subviews)
            {
                if ([obj isKindOfClass:[UIButton class]])
                {
