1. 早些时候尝试从 facebook sdk 登录它工作正常但现在从不同帐户登录后给出“domain=com.facebook.sdk.login code=304”错误。下面是我的代码

{

    if ([AppDelegate getAppDelegate].internetActive) {  

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

        [login logInWithReadPermissions:@[@"public_profile", @"email",@"user_birthday",@"user_friends",@"user_posts"] handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) {

            if (!error)
            {
                NSMutableArray *grantedPermission = (NSMutableArray *)result.grantedPermissions;
                if(![grantedPermission containsObject:@"public_profile"] || ![grantedPermission containsObject:@"email"] || ![grantedPermission containsObject:@"user_birthday"] || ![grantedPermission containsObject:@"user_friends"] || ![grantedPermission containsObject:@"user_posts"])
                {

                         {
                             [self getFacebookProfileInfos];
                         }

                     }];

                }
                else

                    [self getFacebookProfileInfos];
                }
                // There is an error here.

            }


        }];

    UIAlertView *alert=[[UIAlertView alloc] initWithTitle:@"Internet Connection" message:@"Please check Internet connection" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
    [alert show];
}

你试试这段代码来解决你的问题

您获得访问 token 然后注销您的 session 。

FBSDKLoginManager *logMeOut = [[FBSDKLoginManager alloc] init];
[logMeOut logOut];

在您的情况下，您会获得 accessTokens，然后注销 fb session 。
