Question

当我尝试使用PFFacebookUtilsV4将Parse用户与Facebook链接时，它会给我以下警告：

＆＃34;请再次登录此应用以重新连接您的Facebook帐户＆＃34;

以下是我调用PFFacebookUtils的代码块：

/**
 * Import people you are friends with on facebook from the database
 */
- (void)beginImportingFacebookFriendsForUserWithBlock:(void (^)(NSArray *results, NSError *error))cb {

  if (![PFFacebookUtils isLinkedWithUser:[PFUser currentUser]]) {

    NSArray *permissionsArray = @[@"user_about_me", @"user_friends", @"user_events"];
    [PFFacebookUtils linkUserInBackground:[PFUser currentUser] withReadPermissions:permissionsArray block:^(BOOL succeeded, NSError *error) {
      if (succeeded) {
        FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc] initWithGraphPath:@"me"
                                                                       parameters:nil];
        [request startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
          if (!error) {
            NSString *fbId = [result objectForKey:@"id"];
            NSMutableDictionary *currentUserDict = [[prefs objectForKey:@"currentUser"]mutableCopy];
            NSLog(@"currentUserDict:%@",currentUserDict);
            [currentUserDict setObject:fbId forKey:@"fbId"];
            [prefs setObject:currentUserDict forKey:@"currentUser"];
            [prefs setObject:fbId forKey:@"currentFbId"];
            [[PFUser currentUser] setObject:fbId forKey:@"fbId"];
            [[PFUser currentUser] saveInBackground];

            [self finishImportingFacebookFriendsForUserWithBlock:cb];
          }
        }];
      }
    }];
  }
  else {
    [self finishImportingFacebookFriendsForUserWithBlock:cb];
  }
}

- (void)finishImportingFacebookFriendsForUserWithBlock:(void (^)(NSArray *, NSError *))cb {
  FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc] initWithGraphPath:@"me"
                                                                 parameters:nil];
  [request startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
    dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_BACKGROUND, 0), ^{
      if (!error) {
        NSLog(@"result objectforkey:data %@", [result objectForKey:@"data"]);
        cb([result objectForKey:@"data"], error);
      }
      else NSLog(@"error!:%@",error);
    });
  }];
}

以下是我在控制台日志中获得的内容：

2015-08-05 21:18:54.723 Huddlr[2965:391917] error!:Error Domain=com.facebook.sdk.core Code=8 "The operation couldn’t be completed. (com.facebook.sdk.core error 8.)"

    body =     {
        error =         {
            code = 190;
            "error_subcode" = 460;
            message = "Error validating access token: The session has been invalidated because the user has changed the password.";
            type = OAuthException;
        };
    };
    code = 400;
}, NSLocalizedRecoveryOptions=(
    OK,
    Cancel
)}

错误消息是＆＃34;验证访问令牌时出错：会话已失效，因为用户已更改密码。＆＃34;即使密码没有改变。如果有人知道这里发生了什么，我们将不胜感激。

如果您收到错误验证访问令牌 - 代码460-那么您应该注销用户并呼叫登录。

iOS升级到ParseSDK 1.7.5和FacebookSDK 4.4.0后出错
