i m trying load UIImages from server asynchronously in UITableViewCell.
My code worked fine in simulator but not on device. My code as follows,

- (UITableViewCell *)tableView:(UITableView *)tableView
     cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
 IScopeCustomTableCell *cell = (IScopeCustomTableCell *)[tableView dequeueReusableCellWithIdentifier:CellClassName];

if (!cell){
    NSArray *topLevelItems = [cellLoader instantiateWithOwner:self options:nil];
    cell = [topLevelItems objectAtIndex:0];
}

cell.delegate = self;
cell.videoTitle.text = [[videoDataArray objectAtIndex:indexPath.row] objectForKey:@"VideoTitle"];
cell.videoLink = [[videoDataArray objectAtIndex:indexPath.row] objectForKey:@"VideoLink"];
cell.videoThumbnailImageLink = [[videoDataArray objectAtIndex:indexPath.row] objectForKey:@"VideoThumbnail"];
cell.videoThumbnail.tag = indexPath.row;
cell.tag = indexPath.row;
[cell.activityIndicator startAnimating];
NSInvocationOperation *operation = [[NSInvocationOperation alloc]
                                    initWithTarget:self
                                    selector:@selector(loadImage:)
                                    object:cell];
[queue addOperation:operation];
return cell;
}

- (void)loadImage:(IScopeCustomTableCell *)cell {
NSLog(@"Image link :- %@", cell.videoThumbnailImageLink);

//NSData* imageData = [[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:cell.videoThumbnailImageLink]];
NSData* imageData = [NSData dataWithContentsOfURL:[NSURL URLWithString:cell.videoThumbnailImageLink]];
UIImage* image = [UIImage imageWithData:imageData];

cell.videoThumbnail.image = image;
[cell.activityIndicator stopAnimating];
[cell.activityIndicator removeFromSuperview];

//[self performSelectorOnMainThread:@selector(displayImage:) withObject:image waitUntilDone:NO];
}

The above code fine on simulator but not on device, becoz, UIImage *image get (0X0)null in even though NSData loadImage method containing appropriate data.
