NSString *filePath = [[NSBundle mainBundle] pathForResource:@"shareMedia" ofType:@"mp4"];
NSURL *fileURL = [NSURL fileURLWithPath:filePath];
FBSDKShareVideo *vedio = [[FBSDKShareVideo alloc] initWithVideoURL:fileURL previewPhoto:nil];

FBSDKShareVideoContent *vc = [[FBSDKShareVideoContent alloc] init];
vc.video = vedio;

// shareMedia.mp4 is a local video file imported into my project.

We've attempted to use the Photos framework to obtain a PHAsset and it works. However, it requires manually creating the user interface, which is not our preference.

PHFetchOptions *options = [[PHFetchOptions alloc] init];
options.predicate = [NSPredicate predicateWithFormat:@"mediaType = %d", PHAssetMediaTypeVideo];
PHFetchResult *assetsFetchResult = [PHAsset fetchAssetsWithOptions:options];
[assetsFetchResult enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) {
    PHAsset *asset = (PHAsset *)obj;
}];

We prefer to use PHPickerViewController. Unfortunately, it doesn't seem to work as expected. Instead of receiving a PHAsset type, we only obtained a file URL. The same error as mentioned below occurred: "FBSDKErrorDeveloperMessageKey=Must refer to an asset file".

PHPickerConfiguration *configuration = [[PHPickerConfiguration alloc] initWithPhotoLibrary:[PHPhotoLibrary sharedPhotoLibrary]];
configuration.selectionLimit = 1;
configuration.filter = [PHPickerFilter videosFilter];
PHPickerViewController *picker = [[PHPickerViewController alloc] initWithConfiguration:configuration];
if (@available(iOS 14, *)) {
    picker.delegate = self;
} else {
    // Fallback on earlier versions
}
[self presentViewController:picker animated:YES completion:nil];

//delegate
- (void)picker:(PHPickerViewController *)picker didFinishPicking:(NSArray<PHPickerResult *> *)results {
    [picker dismissViewControllerAnimated:YES completion:nil];

    for (PHPickerResult *result in results) {
        if (@available(iOS 14, *)) {
            NSItemProvider *itemProvider = result.itemProvider;
            NSString *assetIdentifier = result.assetIdentifier;
            [itemProvider loadFileRepresentationForTypeIdentifier:@"public.movie" completionHandler:^(NSURL * _Nullable url, NSError * _Nullable error) {
                NSLog(@"Selected video URL: %@", url);
                dispatch_async(dispatch_get_main_queue(), ^{
                    FBSDKShareVideo *vedio = [[FBSDKShareVideo alloc] initWithVideoURL:url previewPhoto:nil];
                    FBSDKShareVideoContent *vc = [[FBSDKShareVideoContent alloc] init];
                    vc.video = vedio;
                    
                    FBSDKShareDialog *dialog = [FBSDKShareDialog dialogWithViewController:self withContent:vc delegate:self];
                    dialog.mode = FBSDKShareDialogModeNative;
                    [dialog show];
                });
     
            }];
        } else {
            // Fallback on earlier versions
        }
    }
