Question

I am currently loading my table with a left-sided thumbnail, title and subtitle using this code:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

    if (cell == nil) {

        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
    }

    NSDictionary *post           = [posts objectAtIndex:indexPath.row];

    cell.textLabel.text       = [post objectForKey:@"post_text"];
    cell.detailTextLabel.text = [post objectForKey:@"post_author_name"];

    NSString *postpictureUrl = [post objectForKey:@"picture"];
    NSData   *data           = [NSData dataWithContentsOfURL:[NSURL URLWithString:postpictureUrl]];

    cell.imageView.image = [UIImage imageWithData:data];

    return cell;
}

Of course this will not work in production due to the synchronous loading I am doing here.

What is your suggestion for asynchronous loading of images in a situation like this?

I’ve found AF Networking (haven’t used it yet) but wonder if there’s a more lightweight approach to this issue.

AsyncImageView is your friend, check it out here.

Just set the imageURL and you are good to go.
