Posting an image to facebook in iPhone

Hi I am using this piece of code to post an image to facebook

UIImage *image_LocalSharePhoto = [[UIImage alloc]initWithData:sharedSingleton.dataResultImage];
NSDictionary* attachment = [NSDictionary dictionaryWithObjectsAndKeys:
                            @"Put Captions On Pics", @"name",
                            @"Put Captions On Pics", @"caption",
                            image_LocalSharePhoto,@"picture",
                            @"I created this fun photo using a FREE app http://bit.ly/CapsPics. #PutCapsOnPics via @PutCapsOnPics", @"description",
                            nil];

NSString *attachmentStr = [jsonWriter stringWithObject:attachment];

NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                               @"532872463436844", @"api_key",
                               @"Share on Facebook",  @"user_message_prompt",
                               attachmentStr, @"attachment",
                               nil];

[facebook dialog: @"feed" andParams:params andDelegate:self];

It opens up facebook page but do not show anything to share or post. Can some one help. Thanks!

if you are using old facebook Method you can wall post like bellow Methid:-

NSArray* permissions = [NSArray arrayWithObjects:@"publish_stream", @"user_photos", nil];
    [facebook authorize:permissions];

now to Post image At your Button Click or your logic like:-

 -(IBAction)ActionPostWallPhoto
    {

         NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                               ImageView.image, @"picture",
                                               nil];

        [[objAppdele facebook] requestWithGraphPath:@"me/feed" andParams:params andHttpMethod:@"POST" andDelegate:self];

    }

and if you are using new facebook API then you can use bellow Method:-

 NSMutableDictionary *postTest = [[NSMutableDictionary alloc]init];
        [postTest setObject:[NSString stringWithFormat@"Your message"] forKey:@"message"];
        [postTest setObject:@"" forKey:@"picture"];
        [postTest setObject:@"" forKey:@"name"];
        [postTest setObject:@"APPID" forKey:@"app_id"];
        NSString *userFBID =[NSString stringWithFormat:@"%@",[allInfoDict objectForKey:@"Friends facebook ID "]];

        [FBRequestConnection startWithGraphPath:[NSString stringWithFormat:@"%@/feed?access_token=%@",userFBID,[appDelegate.mysession accessToken]]
                                     parameters:postTest
                                     HTTPMethod:@"POST"
                              completionHandler:^(FBRequestConnection *connection,
                                                  NSDictionary * result,
                                                  NSError *error) {
                                  if (error) {

                                      NSLog(@"Error: %@", [error localizedDescription]);

                                  } else {
                                      // Success

                                  }
                              }];

        [postTest release];

// aryFetchedImages = Array of images which needs to be posted on Facebook
NSMutableDictionary* params = [[NSMutableDictionary alloc] init];
for (int i = 0; i < aryFetchedImages.count ; i++)
{
        [params setObject:UIImageJPEGRepresentation([aryFetchedImages objectAtIndex:i], 50.0f)  forKey:@"picture"];
        [FBRequestConnection startWithGraphPath:@"me/photos"
                                     parameters:params
                                     HTTPMethod:@"POST"
                              completionHandler:^(FBRequestConnection *connection,
                                                  id result,
                                                  NSError *error)
         {
             if (error)
             {
                 //showing an alert for failure
                #ifdef DEBUG
                    NSLog(@"Unable to share the photo please try later - Fail %@",error);
                #endif
             }
             else
             {
                 //showing an alert for success
                #ifdef DEBUG
                    NSLog(@"Photo %@ uploaded on Facebook Successfully",UIImageJPEGRepresentation([aryFetchedImages objectAtIndex:i], 50.0f));
                #endif

             }
         }];
}
