私は ASIHttpRequest と MB-HUD-progress ライブラリを使用しており、動画ファイルをダウンロードするために MBHUD プログレス バーを表示したいと考えています。両方のライブラリのこのドキュメントを混同しています。初心者には十分ではありません。

これは、アプリ内購入ライブラリで使用している私のコードです。ASSiHttpRequest の以下のメソッドを実装して、両方のライブラリでダウンロードを処理する方法がわかりません

- (void) completeTransaction: (SKPaymentTransaction *)transaction
 {
NSLog(@"Transaction Completed");
// You can create a method to record the transaction.
// [self recordTransaction: transaction];

// You should make the update to your app based on what was purchased and inform user.
// [self provideContent: transaction.payment.productIdentifier];

// Finally, remove the transaction from the payment queue.

HUD = [[MBProgressHUD alloc] initWithView:self.view];
[self.view addSubview:HUD];

// Set determinate mode
HUD.mode = MBProgressHUDModeAnnularDeterminate;
//HUD.delegate = self;
HUD.labelText = @"Downloading";

// myProgressTask uses the HUD instance to update progress
[HUD showWhileExecuting:@selector(myProgressTask) onTarget:self withObject:nil animated:YES];

[self downloadFromURL:[NSURL URLWithString:@"http://techslides.com/demos/sample-videos/small.mp4"]];
[[SKPaymentQueue defaultQueue] finishTransaction: transaction];
    }

   -(void)downloadFromURL:(NSURL *)url
     {

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];

   ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
  filePath = [documentsDirectory stringByAppendingPathComponent:@"small.mp4"];
  NSLog(@"Path is %@",filePath);
  [request setDelegate:self];
  [request setTimeOutSeconds:60];
  [request setNumberOfTimesToRetryOnTimeout:2];
  [request setDownloadDestinationPath:filePath];
  [request startAsynchronous];
  [request setDownloadProgressDelegate:self];
   request.showAccurateProgress = YES;
  }


    - (void)request:(ASIHTTPRequest *)request incrementDownloadSizeBy:(long long)newLength
   {
    NSLog(@"newLength: %lld", newLength);
     }

    -(void)request:(ASIHTTPRequest *)request didReceiveBytes:(long long)bytes {
    NSLog(@"Received bytes:%lld",bytes);

       }

     -(void)requestFinished:(ASIHTTPRequest *)request

   {
 [MBProgressHUD hideHUDForView:self.view animated:YES];
 [self movieReceived];

    }

    -(void)requestFailed:(ASIHTTPRequest *)request
     { 

NSLog(@"%@",request.error);

    }


   -(void)movieReceived
      {
    playerController = [[MPMoviePlayerViewController alloc] initWithContentURL:videoURL];
     }


 - (void)myProgressTask {
// This just increases the progress indicator in a loop
float progress = 0.0f;
while (progress < 1.0f) {
    progress += 0.01f;
    HUD.progress = progress;
    usleep(60000);
}
     }

ファイルサイズに応じてプログレスバーを更新するために myprogresstask のすべての値を変更する方法がわかりません..

どんな助けでも大歓迎です。

ダウンロードの進行状況バーを表示しています。

ASINetworkQueue *requestUserSpecificFileQueue = [[ASINetworkQueue alloc] init];
[requestUserSpecificFileQueue reset];
UIProgressView *progressView=[[UIProgressView alloc]initWithFrame:CGRectMake(5, 190, 200, 20)];
[ViewSelected addSubview:progressView];
[requestUserSpecificFileQueue setDownloadProgressDelegate:progressView];
[requestUserSpecificFileQueue setRequestDidFinishSelector:@selector(downLoadFinished:)];
[requestUserSpecificFileQueue setRequestDidFailSelector:@selector(downloadFailed:)];
[requestUserSpecificFileQueue setShowAccurateProgress:YES];
[requestUserSpecificFileQueue setDelegate:self];
ASIHTTPRequest *requestUserSpecificFile=[ASIHTTPRequest requestWithURL:[dict objectForKey:@"object"]];
requestUserSpecificFile.tag=bookViewSelected.tag;
[requestUserSpecificFile setDownloadDestinationPath:[[self returnUnzipBundlePathName] stringByAppendingPathComponent:dictLocal[@"fullLengthFilename"]]];

__IPHONE_OS_VERSION_MAX_ALLOWED >= __IPHONE_4_0 の場合

[requestUserSpecificFile setShouldContinueWhenAppEntersBackground:YES];

終了

[requestUserSpecificFileQueue addOperation:requestUserSpecificFile];
[requestUserSpecificFileQueue go];
