iOS上傳帶視頻信息的視頻GTLServiceYoutube

Question

我想上傳視頻到youtube channel.i試用下面的Code.the波紋管代碼工作上傳視頻，但問題是，我不能附加它的信息（視頻標題，說明&標籤）。上傳後只顯示視頻標題爲「未知」，沒有標籤或說明。
我見過CodingTofu,Dev7Dev Blog- iOS Sample Code和許多其他Q & A但我不明白我在哪裏犯錯。

NSString* title = video.title; 
    NSString* description = video.videoDescription; 
    NSData* data = video.data; 
    NSMutableArray* tags = video.tags.mutableCopy; 

    GTLYouTubeVideo *yVideo = [GTLYouTubeVideo object]; 
    GTLYouTubeVideoSnippet *snippet = [GTLYouTubeVideoSnippet alloc]; 
    snippet.title = title; 
    snippet.descriptionProperty = description; 

    [tags addObject:DEFAULT_KEYWORD]; 
    NSString* tag = [UploadController generateKeywordFromPlaylistId:UPLOAD_PLAYLIST]; 
    [tags addObject:tag]; 
    snippet.tags = tags; 

    GTLYouTubeVideoStatus *status = [GTLYouTubeVideoStatus alloc]; 
    status.privacyStatus = @"public"; 

    GTLUploadParameters *uploadParameters = [GTLUploadParameters uploadParametersWithData:data MIMEType:@"video/*"]; 
    GTLQueryYouTube *query = [GTLQueryYouTube queryForVideosInsertWithObject:yVideo part:@"snippet,status" uploadParameters:uploadParameters]; 
    service.uploadProgressBlock = ^(GTLServiceTicket* ticket, unsigned long long totalBytesUploaded, unsigned long long totalBytesExpectedToUpload){ 
     CGFloat percentage = totalBytesUploaded/totalBytesExpectedToUpload; 
     NSLog(@"\nUploaded percentage %%(%0.2f)",percentage); 
    }; 
    [service executeQuery:query completionHandler:^(GTLServiceTicket *ticket, GTLYouTubeVideo *insertedVideo, NSError *error) { 
      //[waitIndicator dismissWithClickedButtonIndex:0 animated:YES]; 
      if (error == nil) 
      { 
       NSLog(@"File ID: %@", insertedVideo.identifier); 

       return; 
      } 
      else 
      { 
       NSLog(@"An error occurred: %@", error); 

       return; 
      } 
     }]; 

告訴我，如果你需要任何進一步的細節
謝謝。
對不起我的英文不好。

我得到的錯誤， 在上面的代碼中，我要補充

GTLYouTubeVideo *yVideo = [GTLYouTubeVideo object]; 
GTLYouTubeVideoStatus *status = [GTLYouTubeVideoStatus alloc]; 
GTLYouTubeVideoSnippet *snippet = [GTLYouTubeVideoSnippet alloc]; 
******* 
******* 
******* 
yVideo.snippet = snippet;//This part i forgot to add in my code 
yVideo.status = status;//This part i forgot to add in my code 
[service executeQuery........ 

這可能是有益的誰面臨同樣的問題的人。
