title: How to get other control value from UITableViewCell?
body: <p>I have one doubt that how to get other control's value when we select a row or tap on button while having custom tableViewCell. 
  Suppose I have a TableView Cell with a TextField, a Slider and button. Button has action using:</p>
  
  <pre><code>btn.tag = indexPath.row;
  [btn addTarget:self action:@selector(buttonTapped:) forControlEvents:UIControlEventTouchUpInside];
  </code></pre>
  
  <p>Now I can get button on its action method. I need to get textField's value and slider's value on button tap.</p>
  
  <p>The one option is I create a array and store values for these two control in that array and manage this. But I don't think this is correct way to manage it.</p>
  
  <p>Please navigate me to the currect way to get value of UITableViewCell's subview's value.</p>
  
  <p>Thanks</p>
