Question

I am making a test app through that I want to post video on facebook. I am using latest sdk of facebook. But I am not able to post it on facebook.

My code is as below.

NSDictionary *parameters = [NSDictionary dictionaryWithObject:videoData forKey:@"CareAppDemo.mov"];

FBRequest *request = [FBRequest requestWithGraphPath:@"me/videos" parameters:parameters HTTPMethod:@"POST"];

[request startWithCompletionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
                NSLog(@"result: %@, error: %@", result, error);
            }];

Please help me to post video on facebook via my app.

Answer 1

You need to download FacebookSDK first and then add following framework into your project

 FacebookSDK.framework, FBSDKLoginKit.framework, FBSDKShareKit.framework, Bolts.framework,FBSDKCoreKit.framework 

import them, and write followin code

if(![FBSDKAccessToken currentAccessToken])
    {
        FBSDKLoginManager *login1 = [[FBSDKLoginManager alloc]init];

        [login1 logInWithPublishPermissions:@[@"publish_actions"] handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) {

            FBSDKShareVideo *video = [[FBSDKShareVideo alloc] init];

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

            [FBSDKShareDialog showFromViewController:self withContent:content delegate:nil];




        }];
    }
    else {
        FBSDKShareVideo *video = [[FBSDKShareVideo alloc] init];
        video.videoURL = videoAssetURL;
        FBSDKShareVideoContent *content = [[FBSDKShareVideoContent alloc] init];
        content.video = video;

        [FBSDKShareDialog showFromViewController:self withContent:content delegate:nil];




    }

The video URL videoURL must be an asset URL. You can get a video asset URL eg from UIImagePickerController.

or for recording video you can take as follow

ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
[library writeVideoAtPathToSavedPhotosAlbum:[NSURL URLWithString:[[NSHomeDirectory() stringByAppendingPathComponent:@"Library/Caches"] stringByAppendingFormat:@"/current.mov"]] completionBlock:^(NSURL *assetURL, NSError *error)
 {

     videoAssetURL =assetURL;

 }];

for more detail you can use https://developers.facebook.com/docs/sharing/ios

        }
}

I GOT Error In first time of App runs:

 The operation couldn’t be completed. (com.facebook.sdk error 5.)

It happens when facebook is being inited. Next time i open my app, it works fine, its always the first time. Tried everything in app, but it seems to be on the Facebook SDK side.

Few causes for seeing com.facebook.sdk error 5 :

• Session is is not open. Validate.
• Facebook has detected that you're spamming the system. Change video name.
• Facebook has a defined limit using the SDK. Try a different app.
• Wrong publish permission. Give publish_actions a spin.
• many more....

Best Example to upload video on Facebook Check it

Download from below link that's only iPhone

Answer 4

Get the publish permission

NSArray* permissions = [[NSArray alloc] initWithObjects:
                            @"publish_stream", nil];
    [facebook authorize:permissions delegate:self];
    [permissions release];

Try this

- (void)fbDidLogin {
    NSString *filePath = [[NSBundle mainBundle] pathForResource:@"sample" ofType:@"mov"];
    NSData *videoData = [NSData dataWithContentsOfFile:filePath];
    NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                   videoData, @"video.mov",
                                   @"video/quicktime", @"contentType",
                                   @"Video Test Title", @"title",
                                   @"Video Test Description", @"description",
                       nil];
    [facebook requestWithGraphPath:@"me/videos"
                         andParams:params
                     andHttpMethod:@"POST"
                       andDelegate:self];
}

This is the old thread but for all the future readers coming, here is how to do it with the currently latest facebook SDK ( v3.24.0 - September 10th 2015 ).

- (IBAction)bntShareOnFacebookAction:(id)sender {

    if ([[FBSDKAccessToken currentAccessToken] hasGranted:@"publish_actions"]) {
        [self shareVideoOnFacebook];
    } else {
        FBSDKLoginManager *loginManager = [[FBSDKLoginManager alloc] init];
        [loginManager logOut];  //very important line for login to work
        [loginManager logInWithPublishPermissions:@[@"publish_actions"]
                handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) {
                        if(!error) {
                            [self shareVideoOnFacebook];
                        } 
                    }];
    }
}

- (void) shareVideoOnFacebook {

    NSString *videoPath = @"/Documents/.../movie.mov";
    NSData *videoData = [NSData dataWithContentsOfURL:[NSURL fileURLWithPath:videoPath]];

    NSMutableDictionary *params = [NSMutableDictionary dictionaryWithCapacity:3L];

    [params setObject:videoData forKey:@"video_filename.MOV"];
    [params setObject:@"Title for this post." forKey:@"title"];
    [params setObject:@"Description for this post." forKey:@"description"];

    [[[FBSDKGraphRequest alloc] initWithGraphPath:@"/me/videos" parameters:params HTTPMethod:@"POST"]
     startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
         if (!error) {
             //video posted
         }
     }];
}

IF you want to Upload/Video sharing you must need to pass the Assets Library URL for the original version of the picked item.

URL e.g assets-library://asset/asset.MOV?id=18BC70A0-208A-4F03-A207-7D57C8863425&ext=MOV

If you are using

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info 

Then you must need to pass

NSURL *url = [info objectForKey:UIImagePickerControllerReferenceURL];

If you using Document Directory Path then first you need to save video into library. You must need to create url link Assets Library URL.

[[PHPhotoLibrary sharedPhotoLibrary] performChanges:^{

    [PHAssetChangeRequest creationRequestForAssetFromVideoAtFileURL:videoURL];

} completionHandler:^(BOOL success, NSError * _Nullable error) {

    if (success) {

        // Fetch Last saved video.
        PHFetchOptions *fetchOptions = [[PHFetchOptions alloc] init];
        fetchOptions.sortDescriptors = @[[NSSortDescriptor sortDescriptorWithKey:@"creationDate" ascending:false]];

        // Get video url.
        PHAsset *fetchResult = [PHAsset fetchAssetsWithMediaType:PHAssetMediaTypeVideo options:fetchOptions].firstObject;
        NSString *assetID = [fetchResult.localIdentifier substringToIndex:(fetchResult.localIdentifier.length - 7)];
        NSURL *assetURL = [NSURL URLWithString:[NSString stringWithFormat:@"assets-library://asset/asset.MOV?id=%@&ext=MOV", assetID]];

        // Share Video.
        FBSDKShareVideo *video = [[FBSDKShareVideo alloc] init];
        video.videoURL = assetURL;

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

        FBSDKShareDialog *shareDialog = [[FBSDKShareDialog alloc] init];
        shareDialog.shareContent = content;
        shareDialog.delegate = (id)self;
        shareDialog.fromViewController = self;
        NSError * error = nil;
        BOOL validation = [shareDialog validateWithError:&error];
        if (validation) {
            dispatch_async(dispatch_get_main_queue(), ^{
                [shareDialog show];
            });
        } else {
            NSLog(@"%@", error.localizedDescription);
        }

    }

}];
