Here's what I did:

Created a delegate protocol with these methods:

- (void)textFieldInCellDidReturn:(UITableViewCell*)cell;
- (void)textFieldInCellDidBeginEditing:(UITableViewCell*)cell;
- (void)textFieldInCellDidEndEditing:(UITableViewCell*)cell;

In the cell:

-(BOOL)becomeFirstResponder
{
    return [self.inputTextField becomeFirstResponder];
}

-(void)textFieldDidBeginEditing:(UITextField *)textField
{
    if ([self.delegate respondsToSelector:@selector(textFieldInCellDidBeginEditing:)])
    {
        [self.delegate textFieldInCellDidBeginEditing:self];
    }
}
-(void)textFieldDidEndEditing:(UITextField *)textField
{
    if ([self.delegate respondsToSelector:@selector(textFieldInCellDidEndEditing:)])
    {
        [self.delegate textFieldInCellDidEndEditing:self];
    }
}
-(BOOL)textFieldShouldReturn:(UITextField *)textField
{
    if ([self.delegate respondsToSelector:@selector(textFieldInCellDidReturn:)])
    {
        [self.delegate textFieldInCellDidReturn:self];
    }
    return NO;
}

In the view controller and table view delegate, declare the iVar NSIndexPath* indexPathOfFirstResponder and adopt the delegate

- (void)textFieldInCellDidBeginEditing:(UITableViewCell *)cell
{
    indexPathOfFirstResponder = [self.theTable indexPathForCell:cell];
}

-(void)textFieldInCellDidReturn:(UITableViewCell *)cell
{
    NSIndexPath* indexPathForCell = [self.theTable indexPathForCell:cell];
    if(indexPathForCell.row < [self.theTable numberOfRowsInSection:indexPathForCell.section]-1)
    {
        NSIndexPath* nextIndexPathInSection = [NSIndexPath indexPathForRow:indexPathForCell.row+1 inSection:indexPathForCell.section];
        UITableViewCell* nextCellInSection = [self.theTable cellForRowAtIndexPath:nextIndexPathInSection];
        if (nextCellInSection)
        {
            [nextCellInSection becomeFirstResponder];
        }
        else
        {
            indexPathOfFirstResponder = nextIndexPathInSection;
            [self.theTable scrollToRowAtIndexPath:nextIndexPathInSection atScrollPosition:(UITableViewScrollPositionMiddle) animated:YES];
        }
    }
    else
    {
        [self.theTable endEditing:YES];
    }
}

-(void)textFieldInCellDidEndEditing:(UITableViewCell *)cell
{
    indexPathOfFirstResponder = nil;
}

-(void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath
{
    if ([indexPath isEqual:indexPathOfFirstResponder])
    {
        [cell becomeFirstResponder];
    }
}

Set sequential tag for the textField e.g. 0,1,2..... Import textField delegate method textFieldDidEndEditing. Whenever return key is pressed, this method gets called.

Use something like this:

-(void)textFieldDidEndEditing:(UITextField *)textField{
   if(textField.tag == currentTextFieldTag+1){
    [textField becomesFirstResponder];
}
}

in your cell for row function use this code

cell.textField.tag = indexPath.row;

Now implement a UITextFieldDelegate Method

-(void)textFieldDidEndEditing:(UITextField *)textField
{
    NSIndexPath *indexPath = [NSIndexPath indexPathForRow:textField.tag+1 inSection:YOUR_SECTION];

UITableViewCell* cell = [yourTable cellForRowAtIndexPath:indexPath];
[cell.textField becomesFirstResponder]; 


 // if you need  [yourTable reloadRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationAutomatic];
     }

I hope this will help.Thankyou
