How to know who isFirstResponder?

Question

Very beginner obj-c question.

Is it a possibility to ask about who is first responder at the moment? I have a tableView with four custom cells and with textfield in every cell. Link

I tagged textFields from 1 to 4. And I need to realise the possibility of switching between textfields with buttons 'Next' and 'Previous' . So ,for example, in code of button 'Next' I need something like this:

    if ([[txtfld.tag == 1] isFirstResponder) 
    {
     [[txtfld.tag == 2] becomeFirstResponder];
    }

But this code isn't worked because I don't know how to call textField from method where it's not visible. Is it a right way of thinking to resolve this problem, or maybe there is a better approach?

Thanks, Alex

You will need to get reference to your UITableViewCell and then you can use the -viewWithTag method. For example UITextField *textField = (UITextField *)[cell viewWithTag:1];

Then you can check [textField isFirstResponder];

What do you mean to get reference? To set property or set delegate? – Olex Oct 31 '12 at 18:20
