title: How to detect button on which cell was exactly selected
body: <p>Suppose that I have a custom <code>UITableViewCell</code> contains <code>UIButton</code> control. When the user presses the button it should present another view controller with the appropriate info according to which cell was chosen (to be more precise, I have an array of objects used to represent information in the <code>UITableView</code> and I want to transfer this info to the next view controller). The question is how can I detect button on which cell was exactly selected?</p>
  
  <p>Thanks in advance.</p>
