How to pause/resume/cancel my download request in Alamofire

Question

I am downloading a file using Alamofire download with progress but i have no idea how to pause / resume / cancel the specific request.

@IBAction func downloadBtn         


        

Answer 1

Keep a reference to the request created in downloadBtnTapped with a property, and call cancel on that property in pauseBtnTapped.

var request: Alamofire.Request?

@IBAction func downloadBtnTapped() {
 self.request = Alamofire.download(.GET, "http://httpbin.org/stream/100", destination: destination)
}

@IBAction func pauseBtnTapped(sender : UIButton) {
  self.request?.cancel()
}

Answer 2

request.cancel() will cancel the download progress. If you want to pause and continue, you can use:

var request: Alamofire.Request?

@IBAction func downloadBtnTapped() {
 self.request = Alamofire.download(.GET, "http://yourdownloadlink.com", destination: destination)
}

@IBAction func pauseBtnTapped(sender : UIButton) {
  self.request?.suspend()
}

@IBAction func continueBtnTapped(sender : UIButton) {
  self.request?.resume()
}

@IBAction func cancelBtnTapped(sender : UIButton) {
  self.request?.cancel()
}
