使用FBWebdialogs发布给朋友墙

我使用下面的代码在Facebook上发布 ，在Params词典中input所有必需的细节，并添加到FBWebDialogs ，但post不显示在朋友墙上。

NSDictionary *params = @{ @"name" :[NSString stringWithFormat:@"%@",[Data_Dict objectForKey:@"name"]], @"caption" : @"", @"description" :[Data_Dict objectForKey:@"desc_title"], @"picture" : str_link, @"link" : @"", }; [FBWebDialogs presentFeedDialogModallyWithSession:nil parameters:params handler: ^(FBWebDialogResult result, NSURL *resultURL, NSError *error) { if (error) { //NSLog(@"Error publishing story."); [self.indicator stopAnimating]; } else { if (result == FBWebDialogResultDialogNotCompleted) { //NSLog(@"User canceled story publishing."); } else { //NSLog(@"Story published."); } }}]; } }]; 

期待解决这个问题的想法。
