title: Get the row of UITextField inside UITableViewCell
body: <p>I have two <code>UITextFields</code> inside a custom cell of a <code>UITableView</code>.
  I need to edit and store values of the textFields.
  When I click inside a <code>UITextField</code> I have to know the row it belongs to in order to save the value to the correct record of a local array.
  How can I get the row index of the textField?
  I tried :</p>
  
  <pre><code>-(void)textFieldDidBeginEditing:(UITextField *)textField
  {
  
       currentRow = [self.tableView indexPathForSelectedRow].row;
  
  
  }
  </code></pre>
  
  <p>But the currentRow does not change when I click inside the UITextFieldRow.It changes only when I click (select) the entire row...</p>
