FBSDKShareVideo *video = [[FBSDKShareVideo alloc] init];
video.videoURL = videoURL;
FBSDKShareVideoContent *content1 = [[FBSDKShareVideoContent alloc] init];

Thank you for your valuable time

Answer 1

The video cannot be uploaded from document directory. You can achieve this by making video an asset and than give the url of asset to Facebook and on completion handler call delete that video asset from gallery. This is a trick but not a good solution as when you make video an asset of galley it will visible in savedPhotos.

Like Shoaib said, you'll need to make the video into an asset first. Be sure to include #import <AssetsLibrary/AssetsLibrary.h> in your class.

    ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];

    ALAssetsLibraryWriteVideoCompletionBlock videoWriteCompletionBlock = ^(NSURL *newURL, NSError *error) {
        if (error)
        {
            NSLog( @"Error writing image with metadata to Photo Library: %@", error );
        }
        else
        {
            NSLog(@"Wrote image with metadata to Photo Library %@", newURL.absoluteString);

            FBSDKShareVideo* video = [FBSDKShareVideo videoWithVideoURL:newURL];

            FBSDKShareVideoContent* content = [[FBSDKShareVideoContent alloc] init];
            content.video = video;

            [FBSDKShareAPI shareWithContent:content delegate:self];
        }
    };

    NSURL *videoURL = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"demo-video-high-quality" ofType:@"mov"]];

    if ([library videoAtPathIsCompatibleWithSavedPhotosAlbum:videoURL])
    {
        [library writeVideoAtPathToSavedPhotosAlbum:videoURL completionBlock:videoWriteCompletionBlock];
    }

You should first save the video to your Library, then get the correct PHAsset and generate the correct URL:

guard let schemaUrl = URL(string: "fb://") else {
            return //be safe
}
if UIApplication.shared.canOpenURL(schemaUrl) {
    PHPhotoLibrary.requestAuthorization({ [weak self]
        (newStatus) in
        guard let strongSelf = self else {
            return
        }
        if newStatus ==  PHAuthorizationStatus.authorized {
            strongSelf.saveVideoToCameraRoll(url: assetURL, completion: { (result, phAsset) in
                phAsset?.getURL(completionHandler: { (url) in
                    if let url = url {
                        dispatchAsyncOnMainQueue {
                            let video = FBSDKShareVideo()
                            video.videoURL = url
                            let content = FBSDKShareVideoContent()
                            content.video = video
                            dialog.shareContent = content
                            dialog.show()
                        }
                    }
                })
            })                        
        } else {
            //unauthorized
        }
    })
} else {
    //facebookAppNotInstalled
}


...

func saveVideoToCameraRoll(url: URL, completion:@escaping (Bool, PHAsset?) -> ()) {
    PHPhotoLibrary.shared().performChanges({
        PHAssetChangeRequest.creationRequestForAssetFromVideo(atFileURL: url)
    }) { saved, error in
        if saved {
            let fetchOptions = PHFetchOptions()
            fetchOptions.sortDescriptors = [NSSortDescriptor(key: "creationDate", ascending: false)]
            fetchOptions.fetchLimit = 1
            let fetchResult = PHAsset.fetchAssets(with: .video, options: fetchOptions).firstObject
            completion(true, fetchResult)
        } else {
            completion(false, nil)
        }
    }
}

...

extension PHAsset {    
    func getURL(completionHandler : @escaping ((_ responseURL : URL?) -> Void)){
         if self.mediaType == .video {
            let options: PHVideoRequestOptions = PHVideoRequestOptions()
            options.version = .original
            let nameParts = self.localIdentifier.components(separatedBy: "/")
            if nameParts.count > 0 {
                let assetFormatString = "assets-library://asset/asset.MP4?id=%@&ext=MP4"

                let name = nameParts[0]
                let urlString = String(format: assetFormatString, name)
                if let url = URL(string: urlString) {
                    completionHandler(url)
                } else {
                    completionHandler(nil)                    
                }
            }

        }
    }
}

You just try below code may it's help to you.

- (void)upload{
    if (FBSession.activeSession.isOpen) {
        NSString *filePath = [[NSBundle mainBundle] pathForResource:@"demo-video-high-quality" ofType:@"mov"];
        NSURL *pathURL = [[NSURL alloc]initFileURLWithPath:filePath isDirectory:NO];
        NSData *videoData = [NSData dataWithContentsOfFile:filePath];

        NSDictionary *videoObject = @{
                                      @"title": @"FB SDK 3.1", 
                                      @"description": @"hello there !", 
                                      [pathURL absoluteString]: videoData
                                     };
        FBRequest *uploadRequest = [FBRequest requestWithGraphPath:@"me/videos"
                                                        parameters:videoObject
                                                        HTTPMethod:@"POST"];

        [uploadRequest startWithCompletionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
            if (!error)
                NSLog(@"Done: %@", result);
            else
                NSLog(@"Error: %@", error.localizedDescription);
        }];
    }
}
