将视频上载到facebook错误2

我正在尝试将iphone应用程序拍摄的视频上传到Facebook

在我的应用程序的.plist中，我添加了

FacebookAppId、FacebookDisplayName、URLSchemes，我已经向Facebook开发者注册了我的应用程序

在iPhone设置中，我的应用程序可以使用Facebook帐户

然后我允许我的用户对视频进行标题和描述，然后点击一个按钮将其上传到Facebook

 - (void)buttonRequestClickHandler:(id)sender {

        if (FBSession.activeSession.isOpen) {
  //this is the path to the video          
            NSString *audioName = [pictureDictionary4 objectForKey:@"photoVideokey"];
            NSArray *pathsa = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
            NSString *documentsDirectorya = [pathsa objectAtIndex:0];
            NSString *moviePath = [documentsDirectorya stringByAppendingPathComponent:@"/Movie"];
            NSString *fullPatha = [moviePath stringByAppendingPathComponent:audioName];

NSURL *pathURL = [[NSURL alloc]initFileURLWithPath:fullPatha isDirectory:NO];
            NSData *videoData = [NSData dataWithContentsOfFile:fullPatha];

//these are the title and description of the video
NSString *titleString = self.videotitle.text;
            NSString *descripString = self.descrp.text;

            NSDictionary *videoObject = @{
                                          @"title":titleString,
                                          @"description": descripString,
                                          [pathURL absoluteString]: videoData
                                          };
            FBRequest *uploadRequest = [FBRequest requestWithGraphPath:@"me/videos"
                                                            parameters:videoObject
                                                            HTTPMethod:@"POST"];

           [uploadRequest startWithCompletionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
                if (!error)
                    NSLog(@"Done: %@", result);
                else
                    NSLog(@"Error: %@", error.localizedDescription);}];
        }

这就是操作无法完成时出现的错误。（com.facebook.sdk错误2。） 因此，显然我没有从appDelegate获得会话，也没有在此处登录。

                                   @"description": descripString,
                                   [pathURL absoluteString]: videoData};
    FBRequest *uploadRequest = [FBRequest requestWithGraphPath:@"me/videos"
                                                                 parameters:videoObject
                                                                 HTTPMethod:@"POST"];
    [uploadRequest startWithCompletionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
                      if (!error)
                      NSLog(@"Done: %@", result);
      else
                      NSLog(@"Error: %@", error.localizedDescription);}];
                                              }}];
        }}

有人能看到我在登录会话时哪里出了问题吗

如果有人能帮我，我将不胜感激。

所以我稍微改变了一下。我正在使用HelloFacebookSample应用程序中的代码来确保我已登录并且不再出现错误2。调试器显示视频开始上传，因为它显示视频数据的NSLog。然而，过了一段时间，数据流开始显示00000000 00000000 00000000 00000000，然后可能会显示一些类似于6d766578 00000020的数据流，然后随着频率的增加再次返回到零。然后，最后它错误了 2013-06-27 22:50:14.407我的小世界应用程序[8145:907]错误：操作无法完成。（com.facebook.sdk错误5）

不确定这意味着什么，但将发布另一个问题。

这与Xcode无关。在某种程度上，这与Xcode有关，因为我试图将facebook视频上传集成到使用Xcode@userXXX如果你使用Eclipse，你会考虑这个问题吗？或者

emacs

和

make

？我怀疑。
