Question

I have a UITextField in a custom section header. There are multiple sections using this style of header, and therefore multiple UITextFields.

I have implemented the UITextFieldDelegate. When I edit one of these UITextFields, it calls the delegate method textFieldDidEndEditing. How do I determine which section header this UITextField was in? I need to save the value to core data in the appropriate NSManagedObject for that section.

Many thanks in advance

EDIT: Several people have suggested using a tag of the section number when creating the cell, which would work perfectly. However, I have already assigned the UITextField a tag to distinguish it as a ‘header’ textfield as opposed to a cell textfield or a ‘footer’ textfield. There are a whole lotta textfields on this table!!

Further EDIT: Using in indexPath has been suggested. This would be my preferred solution if I can get it to work. Does anyone know if headers and footers have indexPaths?

You could use tags to identify UITextField instances. Since you’re already setting tags in UITextField instances, set the tags on the section views itself:

- (UIView *) tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
  UIView *sectionView = ... // your section view instance

  // assign the section index as the tag
  sectionView.tag = section; 

  return sectionView;
}

In the textfield delegate, get the section index from the sender’s parent:

- (void) textFieldDidEndEditing:(UITextField *)textField; 
{
  NSInteger theSectionIndex = textField.superview.tag;
  // your custom logic here
}
