Question

我创建了一个Facebook应用程序。我在sandbox mode进行了测试，结果没问题。

现在我想让其他人在手机上测试此应用，因此我关闭了sandbox mode，我发现iPhone-5用户无法登录，但在android中仍能正常使用电话

这是错误日志 -

会话创建错误：错误Domain = com.facebook.sdk Code = 2“操作无法完成。（com.facebook.sdk错误2）”UserInfo = 0x16561ad0

我检查了我的bundle id和app id，它没有出错

这对我有用：

转到iPhone的设置应用。打开您的Facebook设置向下滚动到您的应用，确保您的应用允许Facebook互动。这可能发生在任何设备上，因此在您的应用程序中，您必须确保正确处理此错误。我估计你向用户提供反馈为何登录Facebook失败并要求用户在他们的设备上检查他们的Facebook设置。

- (void)facebookSessionStateChanged:(FBSession *)session state:(FBSessionState)state error:(NSError *)error{       switch (state) {
    case FBSessionStateOpen:
        // handle successful login here
    case FBSessionStateClosed:
    case FBSessionStateClosedLoginFailed:
        [FBSession.activeSession closeAndClearTokenInformation];

        // handle error here, for example by showing an alert to the user
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Could not login with Facebook"
                                                        message:@"Facebook login failed. Please check your Facebook settings on your phone."
                                                       delegate:nil
                                              cancelButtonTitle:@"OK"
                                              otherButtonTitles:nil];
        [alert show];

        break;
    default:
        break;
}

我使用了以下方式并为我工作：

-(void)openFacebookAuthentication
{
    NSArray *permission = [NSArray arrayWithObjects:kFBEmailPermission,kFBUserPhotosPermission,kFBUserPublicPermission,kFBUserLikePermission, nil];

    FBSession *session = [[FBSession alloc] initWithPermissions:permission];
    [FBSession setActiveSession: [[FBSession alloc] initWithPermissions:permission]];
    [[FBSession activeSession] openWithBehavior:FBSessionLoginBehaviorForcingWebView completionHandler:^(FBSession *session, FBSessionState status, NSError *error) {
        switch (status) {
            case FBSessionStateOpen:
                [self likeFaceBook];
                break;
            case FBSessionStateClosedLoginFailed: {
                // prefer to keep decls near to their use
                // unpack the error code and reason in order to compute cancel bool
                NSString *errorCode = [[error userInfo] objectForKey:FBErrorLoginFailedOriginalErrorCode];
                NSString *errorReason = [[error userInfo] objectForKey:FBErrorLoginFailedReason];
                BOOL userDidCancel = !errorCode && (!errorReason || [errorReason isEqualToString:FBErrorLoginFailedReasonInlineCancelledValue]);
                if(error.code == 2) {
                    UIAlertView *errorMessage = [[UIAlertView alloc] initWithTitle:kFBAlertTitle
                                                                           message:kFBAuthenticationErrorMessage
                                                                          delegate:nil
                                                                 cancelButtonTitle:kOk
                                                                 otherButtonTitles:nil];
                    [errorMessage performSelectorOnMainThread:@selector(show) withObject:nil waitUntilDone:YES];
                    errorMessage = nil;
                }
            }
                break;
                // presently extension, log-out and invalidation are being implemented in the Facebook class
            default:
                break; // so we do nothing in response to those state transitions
        }
    }];
    permission = nil;
}
