title: Can't get values from text fields from UITableView
body: <p>I have a <code>UITableView</code> that I used for username/password enter.
  But I have problem to get values when I click on button.
  This is how I make table:</p>
  
  <pre><code>- (UITableViewCell *)tableView:(UITableView *)table cellForRowAtIndexPath:(NSIndexPath *)indexPath {
  
      static NSString *kCellIdentifier = @"Cell";
  
      UITableViewCell *cell = [self.tableView dequeueReusableCellWithIdentifier:kCellIdentifier];
      if (cell == nil) {
          cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault
                                         reuseIdentifier:kCellIdentifier];
          cell.accessoryType = UITableViewCellAccessoryNone;
  
          if ([indexPath section] == 0) {
              UITextField *playerTextField = [[UITextField alloc] initWithFrame:CGRectMake(110, 10, 185, 30)];
              playerTextField.adjustsFontSizeToFitWidth = YES;
              playerTextField.textColor = [UIColor blackColor];
              if ([indexPath row] == 0) {
                  playerTextField.placeholder = @"example@gmail.com";
                  playerTextField.keyboardType = UIKeyboardTypeEmailAddress;
                  playerTextField.returnKeyType = UIReturnKeyNext;
              }
              else {
                  playerTextField.placeholder = @"Required";
                  playerTextField.keyboardType = UIKeyboardTypeDefault;
                  playerTextField.returnKeyType = UIReturnKeyDone;
                  playerTextField.secureTextEntry = YES;
              }
              playerTextField.backgroundColor = [UIColor whiteColor];
              playerTextField.autocorrectionType = UITextAutocorrectionTypeNo;
              playerTextField.autocapitalizationType = UITextAutocapitalizationTypeNone;
              playerTextField.textAlignment = NSTextAlignmentLeft;
              playerTextField.tag = 0;
  
              playerTextField.clearButtonMode = UITextFieldViewModeNever;
              [playerTextField setEnabled: YES];
  
              playerTextField.backgroundColor = [UIColor clearColor];
  
              cell.selectionStyle = UITableViewCellSelectionStyleNone;
  
              [cell addSubview:playerTextField];
  
          }
      }
      if ([indexPath section] == 0) { // Email &amp; Password Section
          if ([indexPath row] == 0) { // Email
              cell.textLabel.text = @"Email";
          }
          else {
              cell.textLabel.text = @"Password";
          }
      }
      return cell;
  }
  </code></pre>
  
  <p>And this is what I have tried in button tap:</p>
  
  <pre><code>...
  for (UITableViewCell* aCell in [self.tableView visibleCells] ) {
          UITextField* aField = (UITextField *)[aCell viewWithTag:0];
          NSLog(aField.text);
      }
  ..
  </code></pre>
  
  <p>This prints me just: Email Password (labels not data that I entered).
  How to get entered values here?</p>
