出现错误，在 Facebook IOS 上发布

Question

我正在使用最新版本的 facebook sdk 4.1 for IOS，但是当我发布图像和文本时，它会出错。下面是我的代码 -

NSArray *permissions = [[NSArray alloc] initWithObjects: @"publish_actions", @"user_photos", nil];

        [FBSession openActiveSessionWithPublishPermissions:permissions defaultAudience:FBSessionDefaultAudienceFriends allowLoginUI:YES completionHandler:^(FBSession *session,FBSessionState status,NSError *error)
         {
             if (error)
             {

             }
             else if(FB_ISSESSIONOPENWITHSTATE(status))
             {
                 [[FBRequest requestForMe] startWithCompletionHandler:
                  ^(FBRequestConnection *connection, NSDictionary<FBGraphUser> *user, NSError *error) {
                      if (!error)
                      {
                          NSDictionary *parameters = [NSDictionary dictionaryWithObjectsAndKeys:
                                                      imgShare,@"picture", txtViewPost.text,@"message",
                                                      nil];

                          FBRequest *request = [FBRequest requestWithGraphPath:@"me/feed"
                                                                    parameters:parameters
                                                                    HTTPMethod:@"POST"];

                          FBRequestConnection *connection = [[FBRequestConnection alloc] init];

                          [connection addRequest:request
                               completionHandler:^(FBRequestConnection *connection, id result, NSError *error)
                           {
                               if (!error)
                               {
                                   isFacebookActive = YES;
                                   [btnFacebook setImage:[UIImage imageNamed:@"facebook-round-active-btn.png"] forState:UIControlStateNormal];
                                   NSLog(@"Photo uploaded successfuly! %@",result);

                               }
                               else
                               {
                                   NSLog(@"Photo uploaded failed :( %@",error.userInfo);
                                   isFacebookActive = NO;
                                   [btnFacebook setImage:[UIImage imageNamed:@"facebook-round--btn.png"] forState:UIControlStateNormal];
                               }
                           }];
                          [connection start];

                      }
                  }];

             }
         }];

以下是错误日志

将代码“me/feed”更改为“me/photos”后，它对我有用。

FBRequest *request = [FBRequest requestWithGraphPath:@"me/photos" 参数：参数 HTTP方法:@"POST"];
