copied!<p>First of all replace </p> <pre> [record setValue:[UIImage imageWithData:imageData] forKey:@"actualImage"]; with [record setObject:[UIImage imageWithData:imageData] forKey:@"actualImage"]; </pre> <p>and your code should work. Since the dictionary is always empty it always goes to else block. Print NSMutableDictionary and you will realize this.</p> <p>This is not the way caching is done. It's not only about memory but also about coding practices. </p> <p>Please use a clean approach like NSCache or <a href="https://github.com/rs/SDWebImage" rel="nofollow">SDWebImage</a></p> <p>SDWebImage takes care of caching as well. Use NSOperation to make request rather than GCD. to avoid nested blocks and concerrency issues. Here is how a clean code looks like</p> <pre> - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"cell"; NewsCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath]; NewsItem *item = [newsItemsArray objectAtIndex:indexPath.row]; cell.newsTitle.text = item.title; // category from library [cell.imageView setImageWithURL:newsItem.imageURL]; if ([item needsRefresh] ) { cell.newsTitle.text = item.title; NewsOperation *operation = [[NewsOperation alloc] initForNewsItem:newItem completion:^(NewsItem *newsItem, NSError *error) { if (newsItem) { [tableView reloadRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationNone]; } }]; [[self newsItemQueue] addOperation:operation]; } return cell; } </pre>
