how to direct the Facebook button to a certain view controller
我已经为我的应用程序创建了一个登录按钮,该应用程序的登录和注销功能起作用。我目前遇到的问题是,一旦用户登录到应用程序,它只会显示一个注销按钮。我希望应用程序将segue定向到我的主视图控制器。 [一旦登录的用户显示此屏幕,我希望该用户直接进入主主屏幕] [1]
这是应用程序的主屏幕,我希望用户在此输入登录详细信息,一旦成功,我希望将用户带到该屏幕
用于登录屏幕和我的应用程序委托
的以下代码

您可以使用
-(void)loginButton:(FBSDKLoginButton *)loginButton didCompleteWithResult:(FBSDKLoginManagerLoginResult *)result error:(NSError *)error
{
[self performSegueWithIdentifier:@"Segueid"sender:self];
}
通过Facebook成功登录后将调用此方法。
