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]];



cell addSubview

if (cell==nil)

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.

var tblArray:[Any] = [""]

Hope this anyone who is looking for Swift answer.

Happy coding.
