UPDATE FOR SWIFT 4

Instead of reloading the whole table you can use beginUpdate and endUpdate here.

Add target to the cell button(You can use view tag or create new TableviewCell class).

    cell.addBtn.tag = indexPath.row
    cell.addBtn.addTarget(self, action: #selector(self.addTextField(_:)), for: UIControlEvents.touchUpInside)
    cell.txtField.tag = indexPath.row

Then implement this method:

@objc func addTextField(_ sender:UIButton) {

    let indexPath = IndexPath(row: sender.tag, section: 0)

    if let cell = tblView.cellForRow(at: indexPath) as? TableCell {
        tblArray.append(cell.txtField.text!)
    }

    let newRow = IndexPath(row: sender.tag + 1, section: 0)
    tblView.beginUpdates()
    tblView.insertRows(at: [newRow], with: .left) 
    tblView.endUpdates()
}

Do not forget to put var tblArray:[Any] = [""] at start.

Hope this anyone who is looking for Swift answer.

Happy coding.

This pseudocode might be a starting point:

// define an NSMutableArray called fields

- (IBAction)addField:(id)sender {
    // create a new text field here and add it to the array
    // then reload data
}

- (IBAction)save:(id)sender {
    for(UITextField *textField in fields) {
        // whatever you have to do
    }
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    // you have as many rows as textfields
    return [fields count];
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    static NSString *CellIdentifier = @"Cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
    }
    // Set up the cell...
    // For row N, you add the textfield N to the array.
    [cell addSubview:(UITextField *)[fields objectAtIndex:indexPath.row]];
}
