Facebook düğmesinin belirli bir denetleyiciye nasıl yönlendirileceği

Question

Uygulamam için bir giriş düğmesi oluşturdum, giriş ve çıkış özellikleri uygulama için çalışıyor. Şu anda sahip olduğum problem, kullanıcı uygulamaya girdikten sonra sadece bir çıkış düğmesi göstermesidir. Uygulamanın segue'i ana görünüm kontrol cihazına yönlendirmesini istiyorum. Bunun giriş yapan kullanıcı bu ekranı görüntüler ettiğinde [i ana ana ekranına doğrudan olmak için kullanıcı istiyorum ][1]

this is the main screen of the application, i would like the user to enter there login detail, once that has been a success i would like the user to be taken to this screen

Answer 1

FBSDKLoginButton - FBSDKLoginButtonDelegate'un delege yöntemini kullanabilirsiniz.

-(void)loginButton:(FBSDKLoginButton *)loginButton didCompleteWithResult:(FBSDKLoginManagerLoginResult *)result error:(NSError *)error

{

[self performSegueWithIdentifier:@"Segueid"sender:self];

}

Bu yöntem, başarılı bir şekilde Facebook üzerinden oturum açmaya çağrılacaktır.
