Save gif to iOS Photo Library in Swift

问题:

I'm traing to save a GIF image located in temp file already created with Regift code.

Regift: https://github.com/matthewpalmer/Regift

The thing is that after saving with PHPhotoLibrary the GIF become a still image.

In other questions there's answers that refeer AssetsLibrary but this has been deprecated by Apple and doesn't work for iOS 10.

Gif can be save through Activity ViewController. Give url in activity controller and save through that you will get gif in camera roll [https://www.youtube.com/watch?v=-DdXUIjuAk0&feature=youtu.be]

let activityViewController = UIActivityViewController(
        activityItems: [url],
        applicationActivities: nil)

    activityViewController.popoverPresentationController?.sourceView = view
    activityViewController.popoverPresentationController?.sourceRect = view.frame
    present(activityViewController, animated: true, completion: nil)

You can save GIF via PHPhotoLibrary.

PHPhotoLibrary.shared().performChanges({
    let request = PHAssetCreationRequest.forAsset()
    request.addResource(with: .photo, fileURL: 'YOUR_GIF_URL', options: nil)
}) { (success, error) in
    if let error = error {
        print(error.localizedDescription)
    } else {
        print("GIF has saved")
    }
}
