在ios上使用社交框架登录facebook时出现问题

我正在使用这段代码登录facebook，它在6.7版本的facebook应用程序中运行得非常好

当facebook应用程序的版本为6.8时，登录不起作用！ 有人能想象发生了什么事

我使用的代码是

ACAccountType *facebookTypeAccount = [self.accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook];

    [self.accountStore requestAccessToAccountsWithType:facebookTypeAccount
                                               options:@{ACFacebookAppIdKey:facebookAppNumber, ACFacebookPermissionsKey: @[@"email"]}
                                        completion:^(BOOL granted, NSError *error)
     { 

         if(granted)
         {
             NSArray *accounts = [self.accountStore accountsWithAccountType:facebookTypeAccount];
             //NSLog(@"accounts %@",accounts);
             self.facebookAccount = [accounts lastObject];

             checkFbStatus = statusWaiting;
             [self me];
             userFbEmail = [jay valueForKey:INFO_FB_EMAIL];
             facebookId = [jay valueForKey:INFO_FB_ID];

         }
         else
         {

             NSLog(@"one");
             //aqui você 
             if([error code]== ACErrorAccountNotFound)
             {

                 //[SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook];
                 SLComposeViewController * fb = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];
                 fb.view.hidden = YES;
                 [self presentViewController:fb animated:NO completion:nil];
                 checkFbStatus = statusFailed;

                 //Adicione sua conta de facebook nas configurações.

             }
             else
             {

                 //Erro desconhecido ou então o usuário não deu permissão.

                 checkFbStatus = statusFailed;


             }
         }
     } ];

我面临同样的问题：

不得不

@property (strong, nonatomic) FBSession *session;

in AppDelegate

in

(void)applicationDidBecomeActive:(UIApplication *)application { [FBAppEvents activateApp]; [FBAppCall handleDidBecomeActiveWithSession:self.session]; }
in

(void)applicationWillTerminate:(UIApplication *)application { [self.session close]; }
in

(BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation { return [FBAppCall handleOpenURL:url sourceApplication:sourceApplication withSession:self.session]; }
in your settings class

if (appDelegate.session.isOpen) {

        [FBSession setActiveSession:appDelegate.session];
        [[FBRequest requestForMe] startWithCompletionHandler:^(FBRequestConnection *connection,
NSDictionary *user, NSError *error) { [self registerationWithFBRequestConnection:connection andFBGraphUser:user andNSError:error]; }];

    }
    else
    {
        [appDelegate.session closeAndClearTokenInformation];
        NSArray *permissions = [NSArray arrayWithObjects:@"email", nil];
        appDelegate.session = [[FBSession alloc] initWithPermissions:permissions];
        [FBSession setActiveSession:appDelegate.session];

        [appDelegate.session openWithBehavior:(FBSessionLoginBehaviorWithFallbackToWebView)
completionHandler:^(FBSession *session, FBSessionState status, NSError *error) { [self sessionStateChangedWithFBSession:session andFBSessionState:status andNSError:error]; }];

    }
(void)sessionStateChangedWithFBSession:(FBSession*)session andFBSessionState:(FBSessionState)status andNSError:(NSError*) error { switch (status) { case FBSessionStateOpen: { [[FBRequest requestForMe] startWithCompletionHandler:^(FBRequestConnection *connection, NSDictionary *user, NSError *error) {

         [self registerationWithFBRequestConnection:connection andFBGraphUser:user andNSError:error];
     }]; }
    break;
case FBSessionStateClosed:

    break;
case FBSessionStateClosedLoginFailed:

    break;
default:
    break;
} }

在您的in

registerationWithFBRequestConnection
