FB目标c共享

Question

我正在尝试与Facebook分享视频但由于某种原因没有任何共享。我之前用图像尝试了它并且它有效但当我尝试视频时它没有用。除非是在网络服务器上，否则你不能分享视频给Facebook吗？

目标代码：

NSString *filePath = [[NSBundle mainBundle] pathForResource:@"sample_movie" ofType:@"mov"];
NSData *videoData = [NSData dataWithContentsOfFile:filePath];



NSMutableDictionary<FBOpenGraphObject> *object = [FBGraphObject openGraphObjectForPost];
object.provisionedForPost = YES;

// for og:title
object[@"title"] = @"Roasted pumpkin seeds";

// for og:type, this corresponds to the Namespace you've set for your app and the object type name
object[@"type"] = @"namespace:video.other";

object[@"video"] = videoData;

代码：

-(void)ShareFB {


[FBRequestConnection startWithGraphPath:@"/me/permissions"
                      completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
                          if (!error){
                              NSDictionary *permissions= [(NSArray *)[result data] objectAtIndex:0];
                              if (![permissions objectForKey:@"publish_actions"]){
                                  // Permission hasn't been granted, so ask for publish_actions
