New Facebook SDK FBSession sessionOpenWithPermissions

Question

I've been trying to develop iOS app using Facebook and I'm new. So I've been trying to make

a login with Facebook, followed a tutorial on Facebook and try to implement it.

But I've encountered, [FBSession sessionOpenWithPermissions] not found. When I run the

app, it will force close and say that error. When build the project, it will show warning

yellow exclamation that sessionOpenWithPermission is not found in FBSession

The tutorial outdated? If it is, then what is the new code for the new Facebook SDK for

sessionOpenWithPermission ?

Answer 1

Try This Code

 account = [[ACAccountStore alloc] init];
    accountType = [account accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierTwitter];
    arrayOfAccounts = [account accountsWithAccountType:accountType]; 


    appDelegate= (AppDelegate *)[[UIApplication sharedApplication] delegate];
    chk=appDelegate.chk_login;

    if (!appDelegate.session.isOpen) {
        // create a fresh session object
        appDelegate.session = [[FBSession alloc] init];
        if (appDelegate.session.state == FBSessionStateCreatedTokenLoaded) {
            // even though we had a cached token, we need to login to make the session usable
            [appDelegate.session openWithCompletionHandler:^(FBSession *session,
                                                             FBSessionState status,
                                                             NSError *error) {
                // we recurse here, in order to update buttons and labels

            }];
        }
    }

Maybe this code helps you, put it in your AppDelegate.m class

- (void)sessionStateChanged:(FBSession *)session
                      state:(FBSessionState) state
                      error:(NSError *)error
{
    switch (state) {
        case FBSessionStateOpen: {
            self.loggedinVCController = [[LoggedinVC alloc] initWithNibName:@"LoggedinVC" bundle:nil];
            self.navController = [[UINavigationController alloc]initWithRootViewController:self.loggedinVCController];
            self.window.rootViewControlle`enter code here`r = self.navController;

        }
            break;
        case FBSessionStateClosed:
        case FBSessionStateClosedLoginFailed:
            // Once the user has logged in, we want them to
            // be looking at the root view.
            [self.navController popToRootViewControllerAnimated:NO];

            [FBSession.activeSession closeAndClearTokenInformation];

            self.viewController = [[SampleViewController alloc] initWithNibName:@"SampleViewController" bundle:nil];
            self.window.rootViewController = self.viewController;

            break;
        default:
            break;
    }

    if (error) {
        UIAlertView *alertView = [[UIAlertView alloc]
                                  initWithTitle:@"Error"
                                  message:error.localizedDescription
                                  delegate:nil
                                  cancelButtonTitle:@"OK"
                                  otherButtonTitles:nil];
        [alertView show];
    }
}
- (BOOL)application:(UIApplication *)application
            openURL:(NSURL *)url
  sourceApplication:(NSString *)sourceApplication
         annotation:(id)annotation
{
    return [FBSession.activeSession handleOpenURL:url];
}
- (void)openSession
{
    [FBSession openActiveSessionWithReadPermissions:nil
                                       allowLoginUI:YES
                                  completionHandler:
     ^(FBSession *session,
       FBSessionState state, NSError *error) {
         [self sessionStateChanged:session state:state error:error];
     }];
}
