IOS 12 stopDownload causes downloadFile promise to never resolve

[MarkEAllan]

I have noticed that on IOS 12 if a download started by a call to RNFS.downloadFile is cancelled by calling the RNFS.stopDownload, then the promise returned by RNFS.downloadFile is never resolved. This causes our app to never remove a modal progress screen from display.

This only happens on IOS 12. It is fine on IOS 11.4 (and lower) and Android.

I am happy to share the code if required.

@XiaoMengDuan I am not sure if this is the right solution, but the following worked for me.

In the Downloader.m file,
Replace 'stopDownload' with the following,

• (void)stopDownload
  {
  if (_task.state == NSURLSessionTaskStateRunning) {
  [_task cancel];
  // [_task cancelByProducingResumeData:^(NSData * _Nullable resumeData) {
  // if (resumeData != nil) {
  // self.resumeData = resumeData;
  // _params.resumableCallback();
  // } else {
  NSError *error = [NSError errorWithDomain:@"RNFS"
  code:@"Aborted"
  userInfo:@{
  NSLocalizedDescriptionKey: @"Download has been aborted"
  }];
  return _params.errorCallback(error);
  // }
  // }];

  }
  }

@manjariParthiban Thanks for your solution.
It seems resumableCallback do not cause the rejection of downloadFile promise.
I do not need resume download, so [_task cancel] is fine.
Thanks again.

Did you try passing the jobId as parameter? this is because all downloads contains the task id to identify what is the download in progress since simultaneous downloads are permitted.

RNFS.stopDownload(jobId)

I am using newest version 2.16.1 and It is working as expected on IOS 13
But I do not have any device on IOS 12 to test if this already fixed in newest version.

Guys, having this issue with whatever version of this library using IOS 13.3. Any help? Is this repo still active?

Any updates on this? This issue still very much exists. Makes the stopDownload function practically unusable on iOS.
