Swift: save video from NSURL to user camera roll - ios

Question

I have a variable videoURL of type NSURL.
If I call println(videoURL) it would return something like this:
http://files.parsetfss.com/d540f71f-video.mp4
I have a button set up that should take this videoURL and save the video to the user's camera roll.
The best I have done is this:
UISaveVideoAtPathToSavedPhotosAlbum(videoPath: String!, completionTarget: AnyObject!, completionSelector: Selector, contextInfo: UnsafeMutablePointer<Void>)
While I'm not even sure if this will work or not, I can't figure out how to convert videoFile:NSURL into a videoPath.
Any help is appreciated on this.
Edit:
The following is unsuccessful:
UISaveVideoAtPathToSavedPhotosAlbum(videoURL.relativePath, self, nil, nil)

Answer 1

AssetsLibrary is deprecated
1: import Photos
import Photos
2: Use this code to save video from url to camera library.
PHPhotoLibrary.sharedPhotoLibrary().performChanges({
PHAssetChangeRequest.creationRequestForAssetFromVideoAtFileURL(nsUrlToYourVideo)
}) { saved, error in
if saved {
let alertController = UIAlertController(title: "Your video was successfully saved", message: nil, preferredStyle: .Alert)
let defaultAction = UIAlertAction(title: "OK", style: .Default, handler: nil)
alertController.addAction(defaultAction)
self.presentViewController(alertController, animated: true, completion: nil)
}
}
Swift 3 & Swift 4
PHPhotoLibrary.shared().performChanges({
PHAssetChangeRequest.creationRequestForAssetFromVideo(atFileURL: urlToYourVideo)
}) { saved, error in
if saved {
let alertController = UIAlertController(title: "Your video was successfully saved", message: nil, preferredStyle: .alert)
let defaultAction = UIAlertAction(title: "OK", style: .default, handler: nil)
alertController.addAction(defaultAction)
self.present(alertController, animated: true, completion: nil)
}
}

The accepted answer no longer works with Swift 3.0 & iOS 10.
First, you need to set the following permission in your app's plist file:
Privacy - Photo Library Usage Description
Provide a string that is presented to the user explaining why you are requesting the permission.
Next, import photos:
import Photos
Finally, here is the updated code for Swift 3.0:
PHPhotoLibrary.shared().performChanges({
PHAssetChangeRequest.creationRequestForAssetFromVideo(atFileURL: fileURL)
}) { saved, error in
if saved {
let alertController = UIAlertController(title: "Your video was successfully saved", message: nil, preferredStyle: .alert)
let defaultAction = UIAlertAction(title: "OK", style: .default, handler: nil)
alertController.addAction(defaultAction)
self.present(alertController, animated: true, completion: nil)
}
}

To save video from NSURL to user camera roll
func video(videoPath: NSString, didFinishSavingWithError error: NSError?, contextInfo info: AnyObject)
{
if let _ = error {
print("Error,Video failed to save")
}else{
print("Successfully,Video was saved")
}
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
if let conversationField = self.conversation {
if (mediaType?.isEqual((kUTTypeMovie as NSString) as String))!
{
let theVideoURL: URL? = (info[UIImagePickerControllerMediaURL] as? URL)
if (UIVideoAtPathIsCompatibleWithSavedPhotosAlbum((theVideoURL?.path)!))
{
UISaveVideoAtPathToSavedPhotosAlbum((theVideoURL?.path)!, self, #selector(ConversationDetailsViewController.video(videoPath:didFinishSavingWithError:contextInfo:)), nil)
}
}
self.dismiss(animated: true, completion: nil)
}

Answer 4

Try this instead for saving video in photo library in swift 4.2 and above
func requestAuthorization(completion: #escaping ()->Void) {
if PHPhotoLibrary.authorizationStatus() == .notDetermined {
PHPhotoLibrary.requestAuthorization { (status) in
DispatchQueue.main.async {
completion()
}
}
} else if PHPhotoLibrary.authorizationStatus() == .authorized{
completion()
}
}
func saveVideoToAlbum(_ outputURL: URL, _ completion: ((Error?) -> Void)?) {
requestAuthorization {
PHPhotoLibrary.shared().performChanges({
let request = PHAssetCreationRequest.forAsset()
request.addResource(with: .video, fileURL: outputURL, options: nil)
}) { (result, error) in
DispatchQueue.main.async {
if let error = error {
print(error.localizedDescription)
} else {
print("Saved successfully")
}
completion?(error)
}
}
}
}
Use of function
self.saveVideoToAlbum(/* pass your final url to save */) { (error) in
//Do what you want
}
Don't forgot to import Photos and add Privacy - Photo Library Usage Description to your info.plist

Answer 5

deprecated as of iOS 9
1: import AssetsLibrary
import AssetsLibrary
2: Use this code to save video from url to camera library.
ALAssetsLibrary().writeVideoAtPathToSavedPhotosAlbum(outputFileURL, completionBlock: nil)

Answer 6

Just use it and paste your video's url:
PHPhotoLibrary.sharedPhotoLibrary().performChanges({ () -> Void in
let createAssetRequest: PHAssetChangeRequest = PHAssetChangeRequest.creationRequestForAssetFromVideoAtFileURL(NSURL(string: /* your url */)!)!
createAssetRequest.placeholderForCreatedAsset
}) { (success, error) -> Void in
if success {
//popup alert success
}
else {
//popup alert unsuccess
}
}
