  <p>// this is how I manipulate every cell height</p>
  
  <pre><code>- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath{
      // How do I set the height here, whats the best approach for this. with autolayout BTW
  }
  
  - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
  // I initialize every cell here with my ArrayContainer, nothing much to refer here.
  }
  </code></pre>
