Is there an easy way of adding a cookie to the download request. We have an auth cookie in our app.

Thanks!

I want to customize the downloaded file name, how should I do

I download this project from github. Did a build and I get these errors. I am using Xcode 5.1.1 with iOS 7.1, OSX 10.9.4. What did I miss?

/Users/beanbob/Library/Developer/Xcode/DerivedData/TCBlobDownloadExample-gnfygdwfjhxvaobvtfrjhoycpfpn/Build/Intermediates/TCBlobDownload.build/Debug-iphonesimulator/Documentation.build/Script-C358A5EA18BFE46200F4C317.sh: line 12: /usr/local/bin/appledoc: No such file or directory

zip error: Nothing to do! (/Users/beanbob/Downloads/TCBlobDownload-master/TCBlobDownload/Docs/TCBlobDownloadDocset.zip)
Command /bin/sh emitted errors but did not return a nonzero exit code to indicate failure

When the downloading finished , I will do an md5 calculate to check the file.
Every time I stop and resume downloading a gzip file, the md5 code is error, and if the downloading finished without stop, the md5 code is always correct.

What do you think about:

1. pause/resume downloads
2. possibility to download files using an ios 7 background task? helpful for very large files when you don't want to have the app open all the time

Hi Thibault, thanks for the project, I've been using it for a while and it's wonderful.

Recently I've noticed some suspicious crashes happening and I'm able to narrow it down to the callback block of startDownloadWithURL:customPath:firstResponse:progress:error:complete:method. Turns out the totalLength parameter in progressBlock sometimes returns the maximum value of UInt64, so when I assign it to a 64-bit NSNumber, it causes a segmentation fault.

on Line 205 of TCBlobDownload.m I found:

self.expectedDataLength = self.receivedDataLength + [response expectedContentLength];

the expectedContentLength property of NSURLResponse returns -1 if there is no expectation that can be arrived, at the same time if I pause and resume a download, sometimes receivedDataLength could be 0 (not sure why), so here you could be assigning minus value to expectedDataLength which is a uint64_t. I suggest to check the value before the assignment.

Meanwhile,I'm using TCBlobDownload in my swift project at the moment. I should take your advice and switch to the newest swift version. Again thanks for your hard work :)

Hi thibaultCha.
I using TCBlobDownload download mp3 file in server. When i pause and resume request, AVPlayer get duration return duration fail. I need Help.

My app crash on start seekToEndOfFile.

The log is like that:

Or like that:

Maybe you should catch this Exception or something else

File is depends on devices environment, so it may be failes

is this lib support i386 architecture

The crash was received as unrecognized selector setName sent to instance.
[sharedManager setName:@"TCBlobDownloadManager_SharedInstance_Queue"];

Commenting it worked like a charm. 👍

We need Swift Version

If the user locked the screen the download is stopped. When I searched about it I found in Apple's documentation it recommends using NSURLSession instead of NSURLConnection here apple docs.

Is there a way to prevent the download from stopping when the app enters background. Or do I have to edit the implementation and use NSURLSession.

I am having this "TCBlobDownloader 0x1137e460 went isFinished=YES without being started by the queue it is in" and download is paused.

Extend the actual existing tests and integrate Travis-CI and eventually some coverage.

Just a note, I've started to look at this and the docset download is broken for some reason.

Thanks for this useful library. I have a question. In some cases, some downloads are not finished. After the App is restarted, I cannot get TCBlobDownloader instance, so have no way to call cancelDownloadAndRemoveFile. Then how to remove the download part file?

Hi, Thanks for your project first. It is good to use, but i've found a thread management bug in the project. As I want to download the files one by one, I use - (void)setMaxConcurrentDownloads:(NSInteger)maxConcurrent function and pass 1 as parameter. But after that , the application can only download the first file successfully, which means the rest files won't be download at all! I looked into your code carefully ,and found a thread management bug. You use [runLoop run]; to stop the thread from stopping immediately, but never called CFRunLoopStop(); to stop it. That means the thread will never be released. You can call CFRunLoopStop(); to stop the thread in finishOperation();
By the way, I tested it on ios8.
Thanks for your wonderful work again.

I have added pause and resume feature for multiple file downloads page. Can it be added to the build? Here's code snippet

how i can handle fail of download ?
I want to redownload it

Please help, I cannot download from Google Drive with a given url by Google Drive API.

Requested url:
https://doc-0s-1s-docs.googleusercontent.com/docs/securesc/drir90g4j3pvaif9fq0tld6v4l690pel/2up5t14otqmlosa6anifku6he3b54fce/1452744000000/03385602974198283278/03385602974198283278/0BwJCGF2rR5_9UUtvdUFrRl9HVm8?e=download&gd=true

And here is error:
Error Domain=com.thibaultcha.tcblobdownload Code=1 "Erroneous HTTP status code 401 (unauthorized)" UserInfo={NSLocalizedDescription=Erroneous HTTP status code 401 (unauthorized), TCBlobDownloadErrorHTTPStatusKey=401}

when i run blow code ,log show download speed and remainingTime is 0,why?

TCBlobDownloadManager *sharedManager = [TCBlobDownloadManager sharedInstance];
    
    
    TCBlobDownloader *downloader =[sharedManager startDownloadWithURL:[NSURL URLWithString:@"http://ofqnohifh.bkt.clouddn.com/%E3%80%90%E9%98%BF%E5%8F%B6%E5%90%9B%E3%80%91%E6%81%8B%E7%88%B1%E5%BE%AA%E7%8E%AF%E4%B9%8B%E4%B8%89%E5%88%86%E9%92%9F%E5%B8%A6%E4%BD%A0%E6%B8%B8%E5%B2%B3%E9%98%B3.mp4"] customPath:nil firstResponse:^(NSURLResponse *response) {
        
    } progress:^(uint64_t receivedLength, uint64_t totalLength, NSInteger remainingTime, float progress) {
        
        NSLog(@"speed=%ld,remainingTime=%ld",downloader.speedRate,downloader.remainingTime);
        
    } error:^(NSError *error) {
        
    } complete:^(BOOL downloadFinished, NSString *pathToFile) {
        
    }];

I think it would be a great imporvement if you would check the HTTP status codes in TCBlobDownload.m

connection:(NSURLConnection*)connection didReceiveResponse:(NSURLResponse *)response
{
_expectedDataLength = [response expectedContentLength];

    // checking for status error
    // errors are 4xx or higher
    // see: http://en.wikipedia.org/wiki/List_of_HTTP_status_codes
    NSHTTPURLResponse *res = (NSHTTPURLResponse *)response;
    int httpStatusCode = res.statusCode/100;

    if (httpStatusCode > 3) {
        __autoreleasing NSError *error = [NSError errorWithDomain:kErrorDomain
                                                             code:2

                                                                        [NSString stringWithFormat:NSLocalizedString(@"HTTP error code %d (%@) ", @"HTTP error code {satus code} ({status code description})"), res.statusCode, [NSHTTPURLResponse localizedStringForStatusCode:res.statusCode]]}];
        TCLog(@"Download failed. Error - %@ %@",
              [error localizedDescription],
              [error userInfo][NSURLErrorFailingURLStringErrorKey]);
        if (self.errorBlock) {
            self.errorBlock(error);
        }
        if ([self.delegate respondsToSelector:@selector(download:didStopWithError:)]) {
            [self.delegate download:self didStopWithError:error];
        }

        [self cancelDownloadAndRemoveFile:NO];
    } else {
        if ([TCBlobDownload freeDiskSpace] < _expectedDataLength

I can send you a patch file if you want.

Markus

when you enter a link in the pop-up box on the multiple download page it still downloads all files. The tag to check buttons indexes are incorrect. This needs to be switched to

• (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
  {
  NSLog(@"alertView - buttonIndex: %d ...", buttonIndex);

  if (buttonIndex == 1)
  {
  NSString *urlString = [alertView textFieldAtIndex:0].text;

  NSLog(@"urlString: %@ ...", urlString);
  
  TCBlobDownloader *download = [[TCBlobDownloader alloc] initWithURL:[NSURL URLWithString:urlString]
                                                        downloadPath:kDownloadPath
                                                            delegate:self];
  [self.currentDownloads addObject:download];
  
  [[TCBlobDownloadManager sharedInstance] startDownload:download];
  

  }
  if (buttonIndex == 2)
  {
  for (NSDictionary *downloadInfos in self.defaultDownloads)
  {
  TCBlobDownloader *download = [[TCBlobDownloader alloc] initWithURL:[NSURL URLWithString:downloadInfos[kURLKey]]
  downloadPath:kDownloadPath
  delegate:self];
  [download setFileName:downloadInfos[kNameKey]];
  [self.currentDownloads addObject:download];

      [[TCBlobDownloadManager sharedInstance] startDownload:download];
  }
  

  }

  [self.tableView reloadSections:[NSIndexSet indexSetWithIndex:0]
  withRowAnimation:UITableViewRowAnimationAutomatic];

}

Can download files if app is in background.?

Hi thibaultCha,

Could you show some codes about how to Pause and resume a download?

Thx!

In my app, the view that initiates file downloads using TCBlobDownload is a child view that can be dismissed/dealloc'd. TCBlobDownload continues downloading the files in the background, which is great. However, when the download view is closed and reopened, I lose access to the handlers/delegate, which I need in order to continue updating progress bars in the UI. Is there a way to do this, currently? I tried directly accessing both the delegate and progression/completion properties of TCBlobDownload in order to update them, but these aren't made public. It would be nice if these could either be made public, or provide a method to update them after the download has begun.

Hi!
I'd like to request a feature which I think would be really nice for lots of people:
The current download speed and an estimated value in seconds how long the download could take.

Hi,
first, its a great job!

second, how i can solve for a 416 http when starting a download ?

tnks

• Expose the error domain and error keys
• Fix went isFinished before being executed by the queue it is in -> Fix the mess in notifyFromCompletionWithSuccess: (don't change isFinished if not started)
• Exclude the hardware category from documentation
• Release 2.1.0

• Improve the tests
  • Coverage
  • More robust tests (cancelAllOperations, dependent downloads...)
  • Use httpbin
  • XCT expectations? This is a legacy library so I'm not sure about relying on Xcode 6

Hi,when i download files,some request time out.
The error info is :

But,when i download the single file,it's ok.why?

Hey,

Just as a thought it would be good if you could return the TCBlobDownload object from the TCBlobDownloadManager startDownloadWithURL methods so it's possible to store them and call cancelDownloadAndRemoveFile later.

At the moment it is just returning void so I'm sure if there would be any issues in doing this.

Cheers.

I experienced random crashes in start method in iOS 10:

[runLoop run];

Are this library supporting iOS 10? Are you planning iOS 10 update?

Hello,
First of all I want to say that your work is awesome.
I am currently facing an issue while changing the request timeout in "TCBlobDownload.m", currently the (kDefaultRequestTimeout = 30) this is set to 30 seconds and I have seen that if the download was in progress and the app was minimized than the download will work for 30 seconds and after that the request timeout error will appear. when i change this timeout to 86400 (24 hours) than it only downloads for 4 minutes after the app is minimized and than request time out occurs.

I want to make the download to be active for 24 hours and after that it should display the timeout error.

Any help would be appreciated.

Setting custom path is really useful, but the file has the name taken from the url passed, it should be useful to add a parameter to the downloader to add a custom filename to avoid the need to add custom code to the finish delegate method, e.g. using NSFileManager, to copy the downloaded file to a new file with a different name and delete the downloaded version.

how i can use this project to download multi file in the same time how to pass it to downloaded in parallel

Hi Thibault,

First, thanks for the lib, because downloading large files and do this properly, it's not very easy in ObjC.

Unfortunately, I have random crashs while downloading. Please find below, the error stack :

I also had the error HTTP 416, on one server, when i'm trying to download the same file from another server, it's fine... Bizarre ! :)

Thanks.

Nash.

A tried to make an example with multiples downloads and multiples progress bars using blocks but it was not "funcional" as was using delegate.
By the way, I've implemented an stop/pause for an single item in queue, but to do that I had to change the your code a little.
Could you analise this changes an implement it if you want.
Check out my github.

Sorry about the project name, theres an blackout of creativity.
P.S.: no not make pod install, or my changes in your code will be replaced.

Go to TCBlobDownload Project's Target -> Build Settings -> Architectures, and select Standard architectures (including 64-bit) (armv7, armv7s, arm64) in the Architectures section. Otherwise, you can get the error messages like below:

Undefined symbols for architecture arm64:
  "_OBJC_CLASS_$_TCBlobDownloadManager", referenced from:
      objc-class-ref in SASandArtTableViewController.o
ld: symbol(s) not found for architecture arm64

Hi,
I use TCBlobDownload in my project to download mp3 files.I stop the downloading when the progress goes to about 50% then restart the task.It still start at 0%, I have checked the code, it seem supports the resuming function but the progress do not recover?

I can't download with url from a file of Google Drive. Can you help me ?
Error Domain=com.thibaultcha.tcblobdownload Code=1 "Erroneous HTTP status code 416 (requested range not satisfiable)" UserInfo={NSLocalizedDescription=Erroneous HTTP status code 416 (requested range not satisfiable), TCBlobDownloadErrorHTTPStatusKey=416}

The problem now I am facing is it's stopped responding after downloaded around 60 files. I am using TCBlobDownloader to download thousand of images. I have to restart the app to resume downloading. Again, it's stopped after downloaded around 60 files.

I have many files to downloa. Many of them are mp3 file with size 200KB500KB，and several video with size 10MB40MB. So I code like this :

for (......)
{
[[TCBlobDownloadManager sharedInstance] startDownloadWithURL:url customPath:downloadPath delegate:self];
}

But I find only one or two log printed out from download:didReceiveFirstResponse delegate. All other files all not download. Finaly, a friend told me to comment the code

//        self.speedTimer = [NSTimer scheduledTimerWithTimeInterval:1.0
//                                                           target:self
//                                                         selector:@selector(updateTransferRate)
//                                                         userInfo:nil
//                                                          repeats:YES];
//        [runLoop addTimer:self.speedTimer forMode:NSRunLoopCommonModes];

in method - (void)start in file TCBlobDownload, then download queue will be normal. I try and it indeed works. But I don't and stand why, so my friend too. May you explain this ?

In my project i download mp3 in main view ,and i want to see progress in other view .how can i do .and i want pause and resume a download to that,is right?

I have use TCBlobDownloader to download file. But, I can't get callback from

• (void)download:(TCBlobDownloader *)blobDownload didReceiveData:(uint64_t)received onTotal:(uint64_t)total.

Have I forgotten any thing?

TCBlobDownloadManager *sharedManager = [TCBlobDownloadManager sharedInstance];
TCBlobDownloader *downloader = [sharedManager startDownloadWithURL:url customPath:nil delegate:self];

Thank.

first of all thanks a lot for the great work.
I want to update my view for multiple download using blocks like different download progress update.
