Facebook Login Status Check Problem

Question

Wenn Benutzer öffnen Facebook Setting View, wie den aktuellen Anmeldestatus zu identifizieren. Und wenn es protokolliert wird, wie kann ich die weiteren Informationen der Benutzer abrufen. wie Geburtstag, Alter, Geschlecht, etc.

Ich schrieb dieses Stück Code, der nicht funktioniert. Danke im Voraus.

- (void)viewDidLoad { 
[super viewDidLoad]; 

if ([FBSDKAccessToken currentAccessToken]) { 

    //Going to another ViewController, which include user's name, 
    //age, photo and so on. 
} else { 
    FBSDKLoginButton *loginButton = [[FBSDKLoginButton alloc] init]; 

    loginButton.center = self.view.center; 
    [self.view addSubview:loginButton]; 
} 


} 

Answer 1

if ([FBSDKAccessToken currentAccessToken]) { 
[[[FBSDKGraphRequest alloc] initWithGraphPath:@"me" parameters:nil] 
startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) { 
    if (!error) { 
    NSLog(@”fetched user:%@”, result); 
    } 
}]; 
} 

dieses seine Arbeits Versuchen.

https://developers.facebook.com/docs/ios/change-log-4.xhier Dokument enthält Informationen über SDK 4,0

Hier sind einige Graph API-Schlüssel zu erhalten.

"public_profile", 
"email", 
"user_friends" , 
"user_hometown", 
"user_work_history" , 
"user_birthday" , 
"user_education_history 

Answer 2

ist die umfassende und vollständige Codeinformationen des Benutzers

FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];

    } else if (result.isCancelled) { 
     DLog(@"Cancelled");
