title: check UItextfield name
body: <p>I am accessing textFieldShouldReturn to check if the textfield equals the initalized type, however I am not sure how to do it.</p>
  
  <p>This is what my textFieldShouldReturn method looks like.</p>
  
  <pre><code>- (BOOL)textFieldShouldReturn:(UITextField *)textField
  {
      [[self.view viewWithTag:textField.tag+1] becomeFirstResponder];
      // this means there has been a change in the UItextfield
      NSLog(@"%@", selectedItemDictionary);
      if ([textField isEqual:cell.widthTextField]) {
  
  //..
  </code></pre>
  
  <p>And then cell.widthTextField is a subclassed UITableViewCell with several UITextFields in it. Once of which is called widthTextField.</p>
  
  <p>So my question is, how do you know which textField you are actually in?</p>
