One of my app is to upload video to facebook account. I checked on web, but found that most of solution are old or removed. Is there any updated solution?

Welcome any comment

Context

Before you can publish onto Facebook, you must get publish (write) permissions, using either native integration or the Facebook SDK, the rule is you must first acquire read permissions before write permissions.

Thus, make sure that before you attempt to upload a video, you should have requested basic info (email for example), then, once you have this, you can request write permissions. The permission necessary for uploading videos is publish_stream.

Using iOS 6 native Facebook integration

Using the native iOS 6 Facebook integration, you should use the requestForServiceType:requestMethod:URL:parameters: method of SLRequest, as follows:

- (void)upload{
    NSURL *videourl = [NSURL URLWithString:@"https://graph.facebook.com/me/videos"];

    NSString *filePath = [[NSBundle mainBundle] pathForResource:@"me" ofType:@"mov"];
    NSURL *pathURL = [[NSURL alloc]initFileURLWithPath:filePath isDirectory:NO];
    NSData *videoData = [NSData dataWithContentsOfFile:filePath];

    NSDictionary *params = @{
                            @"title": @"Me being silly",
                            @"description": @"Me testing the video upload to Facebook with the new system."
                            };

    SLRequest *uploadRequest = [SLRequest requestForServiceType:SLServiceTypeFacebook
                                                  requestMethod:SLRequestMethodPOST
                                                            URL:videourl
                                                     parameters:params];
    [uploadRequest addMultipartData:videoData
                           withName:@"source"
                               type:@"video/quicktime"
                           filename:[pathURL absoluteString]];

    uploadRequest.account = self.facebookAccount;

    [uploadRequest performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) {
        NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
        if(error){
            NSLog(@"Error %@", error.localizedDescription);
        }else
            NSLog(@"%@", responseString);
    }];
}

Here it's important to note that the video data does not go into the parameters dictionary, it must be added to the SLRequest object using the addMultipartData:withName:type:filename: method.

Also note that the filename is very important when adding the videos data. Here I am just using the full path of the file.

Using Facebook SDK 3.1 library

If you must support iOS versions earlier then iOS 6 or you wish to use the Facebook SDK 3.1 for any other reason, uploading a video is a little different.

You must use a FBRequest object and a NSDictionary that contains the videos details. The method I recommend using is requestWithGraphPath:parameters:HTTPMethod:, I've used this method out of preference although you should be able to use some of the other methods to create your request object.

The following code works with Facebook SDK 3.1 to upload a video:

- (void)upload{
    if (FBSession.activeSession.isOpen) {
        NSString *filePath = [[NSBundle mainBundle] pathForResource:@"me" 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);
        }];
    }
}

Here as you can see, we add the videos data into the parameters dictionary unlike the previous solution, it's there along with title and description (which are 2 optional parameters). Also note that here there is no key source, as specified by the Facebook documentation. The key's name is the filename of the video. I don't know why this shouldn't be source, but using source results in a com.facebook.sdk error 5.

The bug I mentioned I filed with Facebook, you can see this report on this link - unless I'm mistaken in my interpretation of the documentation. Please try out that bug and report if you can reproduce it. Thanks !


publish_stream is not enough to upload(read), you need to ask for "video_upload" permission.
