Downloading to camera roll using alamofire - ios

Question

I'm using this function to download videos to a file called downloads using alamofire.
How would I edit it so it saves videos to the camera roll
func downloadVideoToCameraRoll() {
let destination: DownloadRequest.DownloadFileDestination = { _, response in
let pathComponent = response.suggestedFilename!
var documentsURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)[0]
let directoryURL: URL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)[0]
let folderPath: URL = directoryURL.appendingPathComponent("Downloads", isDirectory: true)
let fileURL: URL = folderPath.appendingPathComponent(pathComponent)
return (fileURL, [.removePreviousFile, .createIntermediateDirectories])
}
Alamofire.download(firstId, method: .get, parameters: nil, encoding: JSONEncoding.default, to: destination)
.downloadProgress(queue: DispatchQueue.global(qos: .utility)) { progress in
self.progresss.setProgress(Float(progress.fractionCompleted), animated: true)
//print("Progress: \(progress.fractionCompleted)")
}
.validate { request, response, temporaryURL, destinationURL in
// Custom evaluation closure now includes file URLs (allows you to parse out error messages if necessary)
return .success
}
.responseJSON { response in
debugPrint(response)
print(response.temporaryURL!)
print(response.destinationURL!)
}

Answer 1

You can use this in swift 3:
PHPhotoLibrary.shared().performChanges({
PHAssetChangeRequest.creationRequestForAssetFromVideo(atFileURL: urlToYourVideo)
}) { saved, error in
if saved {
print("Saved")
}
}

Try the code below
func downloadVideoToCameraRoll() {
let destination: DownloadRequest.DownloadFileDestination = { _, response in
let pathComponent = response.suggestedFilename!
var documentsURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)[0]
let directoryURL: URL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)[0]
return (directoryURL, [.removePreviousFile, .createIntermediateDirectories])
}
Alamofire.download(firstId, method: .get, parameters: nil, encoding: JSONEncoding.default, to: destination)
.downloadProgress(queue: DispatchQueue.global(qos: .utility)) { progress in
self.progresss.setProgress(Float(progress.fractionCompleted), animated: true)
//print("Progress: \(progress.fractionCompleted)")
}
.validate { request, response, temporaryURL, destinationURL in
// Custom evaluation closure now includes file URLs (allows you to parse out error messages if necessary)
return .success
}
.responseJSON { response in
debugPrint(response)
print(response.temporaryURL!)
print(response.destinationURL!)
saveVideoTo(destinationURL)
}
func saveVideoTo(_ videoUrl:Url?){
if videoUrl != nil {
PHPhotoLibrary.sharedPhotoLibrary().performChanges({ () -> Void in
let createAssetRequest: PHAssetChangeRequest = PHAssetChangeRequest.creationRequestForAssetFromVideoAtFileURL(NSURL(string: videoUrl)!)!
createAssetRequest.placeholderForCreatedAsset
}) { (success, error) -> Void in
if success {
//saved successfully
}
else {
//error occured
}
}
}
}
