推荐答案

PHPhotoLibrary.sharedPhotoLibrary().performChanges({ () -> Void in

        let createAssetRequest: PHAssetChangeRequest = PHAssetChangeRequest.creationRequestForAssetFromVideoAtFileURL(NSURL(string: filePath)!)!
        createAssetRequest.placeholderForCreatedAsset

        }) { (success, error) -> Void in
            if success {

                //popup alert success
            }
            else {
