ios - 有没有办法将实时照片保存到照片库？

Question

我将存储的图像和视频文件传递给:PHLivePhoto.requestLivePhotoWithResourceFileURLs 并获取可以在 PHLivePhotoView 中显示的 PHLivePhoto 对象。但我想知道，一旦我有了 PHLivePhoto，是否有办法将它保存到照片库？

    NSURL *photoURL = ...;
    NSURL *videoURL = ...;   

    [[PHPhotoLibrary sharedPhotoLibrary] performChanges:^{
            PHAssetCreationRequest *request = [PHAssetCreationRequest creationRequestForAsset];


            //These types should be inferred from your files

            //PHAssetResourceCreationOptions *photoOptions = [[PHAssetResourceCreationOptions alloc] init];
            //photoOptions.uniformTypeIdentifier = @"public.jpeg";

            //PHAssetResourceCreationOptions *videoOptions = [[PHAssetResourceCreationOptions alloc] init];
            //videoOptions.uniformTypeIdentifier = @"com.apple.quicktime-movie";

            [request addResourceWithType:PHAssetResourceTypePhoto fileURL:photoURL options:nil /*photoOptions*/];
            [request addResourceWithType:PHAssetResourceTypePairedVideo fileURL:videoURL options:nil /*videoOptions*/];

        } completionHandler:^(BOOL success, NSError * _Nullable error) {
            NSLog(@"success? %d, error: %@",success,error);
        }];
